Instances

About This Search Engine

This search engine for Mastodon instances is based on a database that gets updated by our crawler every night (CET).

Instances are considered new for 30 days after they are discovered.

When an instance has not responded to our daily checks for more than 30 days it is no longer considered in statistics and searches and it gets checked only on the first of the month, rather than daily, until it possibly responds again, or until its last succesful check is one year old; in this latter case, from that moment it gets checked only on the first day of each year.

“Random ordering” of results varies daily.

Default search criteria reflect our fondness for a decentralized and egalitarian Fediverse and our attempt to exclude instances accepting fascist, racist, sexist, ableist, sovereignist, pro-nuclear and pedopornographic contents by marking them as noxious.

To report any issue, technical or non-technical, or to suggest instances to exclude according to the above criteria, please contact us at our e-mail address, masthelp[at]insicuri.net.

Important Notes for Instance Administrators

If you don’t want your instance to show up here, please e-mail us at masthelp[at]insicuri.net.

If your instance is behind a web firewall such as Anubis or Cloudflare, and you want it to be listed here, you must configure the firewall to allow our bot, which makes no more than a dozen HTTP requests per day, to connect to your instance, by whitelisting it by User-Agent and/or IP address. Our bot’s User-Agent is mastodon.help; the IP address from which it makes requests is the same as this site’s, 65.108.133.80.

As of today, Tuesday, July 14, 2026, there is a flaw in the bot code: if a new instance fails to respond to the bot’s first check attempt (it’s rare, but can happen), it will never be checked again; therefore, it will never appear in search results here, unless we add it “manually” (i.e., force a certain script to check it). So, if you’ve launched a new instance and want it listed here, but you notice that it still isn’t showing up a few days after, or later, please e-mail us at masthelp[at]insicuri.net, and we will add it “manually” – until we fix the issue, which should be quite soon.

We currently count 9,703 Mastodon instances, with 10,583,490 users (851,320 active during last month) and 1,110,195,983 published statuses. [Show Threads moderation statistics]

這是一個以中文交流為主、同時歡迎全球使用者加入的 Mastodon 社群。在去中心化的世界裡,我們保留一點距離,也分享一點真實。Even when stories end, conversations can still continue.
Long description
fAiry.iD 是一個獨立的中文 Mastodon 聯邦節點,自 2022 年 02 月穩定運行至今,專注於建立一個安靜、克制、反戾氣的交流空間。

在去中心化的世界裡,人們跨越不同站點與地點相遇。
資訊流動,對話展開。
有時圓潤,有時尖銳。
我們保留距離,也分享真實。

Here, people are always present — across different sites and places. Information flows, conversations unfold. Sometimes it takes smooth wit, sometimes sharp edges. You can hold on or let go, speak sincerely or watch in silence. In this decentralized world, everyone holds a piece of truth, and keeps a piece of distance.

這裡是一些你需要瞭解的內容……

fAiry.iD pledges to follow the Mastodon 'Server Covenant', in addition to our own moderation 'Server Rules'.All are welcome here!

  • 互聯網將無數遠在天邊的人們連接在一起,另一端也是一個與你一樣擁有複雜內心世界的人。請謹慎行事!
  • 請考慮你的帖子可能會傳播很遠,如果內容可能讓某些人不適,請標註相關標籤。
  • 這裡不容許任何形式的騷擾和霸凌行為,遵守服務器規則。
  • 你奢望大眾,所有人去同意你的意見,或者同意你的表達,或者讚賞你的作品,這是一個非常法西斯的思維。
  • 唯有眾聲喧嘩、百花齊放,多年後人們才能從歷史的不同面向和各異表述之中,辨證並取回不會湮沒於時間洪流中的共同記憶。

這裡適合誰?

  • 希望遠離演算法與流量操控的人
  • 想在喧囂之外保有一塊穩定角落的人

如果你重視長期存在,而非短暫熱度,這裡可能適合你。

社群網路,還權予您。歡迎來耍!

分享你的想法從未如此方便。發佈任何你想要的東西:鏈接、圖片、文本、視頻。所有的這些都在一个能够遠離大財團和無廣告的平臺上,你甚至可以取回賬戶數據或者銷燬它。
嘟文 1984 字數上限(1984 Word limit),你可以用焦點調整你的圖片的縮略圖。也可以使用自定義的表情符號,把東西藏在警告標籤(CW)後面,並選擇誰才能看到你的發言。
本站不使用 Cloudflare 等大型 CDN 服務!(not use large CDN services such as Cloudflare.)

  • 圖片與媒體大小限制上限 20MB/200MB (Expanded maximum image and media size limits respectively)
  • 媒體分辨率上限 3840×2160 (Image resolution enhancement)

我們關心基礎設施,也關心對話本身。
在這個去中心化的世界裡,
每個人都握有一部分真實,也保留一部分距離。
歡迎來到這裡!

Short description
This instance is intended to be a non-sectarian space for leftist discussion, along the lines of hexbear.net, but in a federated micro-blogging format.
Long description
Matapacos.dog is an anti-sectarian leftist (read: anti-capitalist, anti-imperialist, above all else) instance, established to welcome discussion of the full spectrum of anti-capitalist tactics and theoretical perspectives in good faith.

Historically, this instance was created as an offshoot of Hexbear.net to dip our toes into the Fediverse (when Lemmy compatibility with the microblogging neighborhood of the Fediverse was even worse than it is today), but it is still best described as "unofficial, Hexbear-adjacent" thing since it was launched and (still is) administered unilaterally by a single person.

Account creation currently requires approval. You don't need to write an elaborate biography or "prove your worthiness" or anything, this is mainly a counter-measure against bots. I do my best to check these once or twice a week.

This instance is a member of the FediPact (https://fedipact.online/). This instance is running Mastodon "Glitch Edition" (https://glitch-soc.github.io/docs/), a fork with a number of cool experimental features, but fewer guarantees of stability. The post character limit has been increased to 2000 characters. Most of the time, full text search and LibreTranslate are also available.
Instance rules
  1. No bigotry or discrimination. It's on sight. If you're being a bigot ironically, you will be removed "ironically."
  2. No sectarianism. If somebody makes a fool of themself, take issue with them and their position. Do not do the Ben Shapiro / Jesse Waters shtick where you fish for insignificant cranks to discredit broad movements. Friendly ribbing is OK.
  3. Apply content warnings to any graphic nudity, drug use, gore (including of animals), suicide, sexual violence, hate crimes, slurs, etc. Allow people to opt-in to these discussions instead of forcing them to opt-out.
  4. We do not reject violence on principle. Our adversaries will not be pacified by rhetoric. Be mindful about the legal implications of what you say though. Explicit threats against living people and organizations will be removed.
  5. Be aware of the visibility and context of your posts. Mastodon is a federated network and different instances have different rules. If users from this instance regularly violate the rules of other instances, we will be de-federated.
  6. Reactionaries are not welcome. Liberals will be made fun of until we grow bored.
  7. Don't get arrested. Don't get me arrested. 😎

It seems like this instance’s server thumbnail’s URL points to a non existent file. This is usually easily fixable by the instance’s admin(s) by uploading again the image to their server. Note that the change won’t be displayed here before the nightly automatic update of this instance’s infos occurs.

About Mastodon

Mastodon is a distributed social media platform, similar to Twitter. There are hundreds of different Mastodon sites in the Fediverse, and you can make an account on any of them and then follow and interact with users across all the different instances. It has easy apps for your phone too! This is a great guide to Mastodon that goes over what it is and will answer many questions you might have.

For using this server, the main things I would advise (which are all in that guide) are:

  • This is a small server, but you don't need more people to join this server to have fun. Think of this like your email host. It doesn't matter if all your friends are here, because you can follow each other anyway and send Toots to each other. Just pick the server you like, post up there, and follow people from other servers.
  • Find your friends from Twitter and follow them
  • Find people and Mastodon instances you like, and follow them. Their posts will appear in your feeds, and posts from their Mastodon instance will appear on your Federated feed.
  • Tell your friends to follow you on Mastodon. Give them our profile URL, or your username of [username]@leftist.network

About Us

leftist.network is a Mastodon server specifically geared towards those with Leftist politics -- though your posts aren't restricted to politics! While you're welcome to follow people from this server if your politics don't fall considerably on the left side of the spectrum, we'd strongly suggest making your Mastodon account elsewhere. This is meant to be a space where Leftists feel welcome, and our Code of Conduct is stricter than other instances.

Lack of Donations

At this time Leftist.Network is small enough that hosting costs are very little, and moderation is quite easy. Currently the admin considers running this part of his donation to the Mastodon community, and if anything would like to support other servers. If there is someday a need for financial support, that will be communicated long before it is truly necessary.

Lack of Privacy

Please remember that public toots made on this instance are public! If you wish to only share your posts with friends, we recommend both:

  1. Setting the privacy of your toots as Followers Only when posting. You can set this as the default under Posting Privacy in the Other section of Preferences
  2. Choose Lock Account in the Profile -> Appearance section of your Preferences (which will only allow accounts to follow yours with approval.)

Even then, as with all other Mastodon instances, your posts and Direct Messages are not encrypted, are still subject to subpoena (for this instance in the United States), and should not be considered secure. You're encouraged to use secure messaging for confidential communications, and we have recommendations below.

Code of Conduct

The following guidelines are not a legal document, and final interpretation is up to the administration of leftist.network; they are here to provide you with an insight into our content moderation policies.

Given that leftist.network will be more restrictive than other Mastodon instances, we've separated out the Code of Conduct into 2 sections:

  • Common Code of Conduct (lifted in almost entirely from mastodon.social, the first mastodon instance)
  • Extended Code of Conduct, with new requirements for leftist.network.

Remember that both apply, and if you're not comfortable with the extended Code of Conduct, we recommend creating your account elsewhere and limiting interactions with accounts on this instance. If posts or messages break either sets of Code of Conduct, users are encouraged to report them.

Common Code of Conduct

  1. The following types of content will be removed from the public timeline:

    1. Excessive advertising
    2. Uncurated news bots posting from third-party news sources
    3. Untagged nudity, pornography and sexually explicit content, including artistic depictions
    4. Untagged gore and extremely graphic violence, including artistic depictions

  2. The following types of content will be removed from the public timeline, and may result in account suspension and revocation of access to the service:

    1. Racism or advocation of racism
    2. Sexism or advocation of sexism
    3. Casteism or advocation of casteism
    4. Discrimination against gender and sexual minorities, or advocation thereof
    5. Xenophobic and/or violent nationalism

  3. The following types of content are explicitly disallowed and will result in revocation of access to the service:

    1. Sexual depictions of children
    2. Content illegal in Germany and/or France, such as holocaust denial or Nazi symbolism
    3. Conduct promoting the ideology of National Socialism

  4. Any conduct intended to stalk or harass other users, or to impede other users from utilizing the service, or to degrade the performance of the service, or to harass other users, or to incite other users to perform any of the aforementioned actions, is also disallowed, and subject to punishment up to and including revocation of access to the service. This includes, but is not limited to, the following behaviors:

    1. Continuing to engage in conversation with a user that has specifically has requested for said engagement with that user to cease and desist may be considered harassment, regardless of platform-specific privacy tools employed.
    2. Aggregating, posting, and/or disseminating a person's demographic, personal, or private data without express permission (informally called doxing or dropping dox) may be considered harassment.
    3. Inciting users to engage another user in continued interaction or discussion after a user has requested for said engagement with that user to cease and desist (informally called brigading or dogpiling) may be considered harassment.


These provisions notwithstanding, the administration of the service reserves the right to revoke any user's access permissions, at any time, for any reason, except as limited by law.

Extended Code of Conduct

Leftist.network is meant to be a space where Leftists feel welcome to discuss their politics, beliefs, and lives openly, without fear of constant criticism or argument. This service is only a vehicle for debate if the users in question have been clear in being open to it.

The following conduct is disallowed and is grounds for removal from this platform:

  • As noted in Common Code of Conduct, continuing to engage in conversation or debate with a user that has specifically requested to stop discussion
  • Sea-Lioning users, a type of harassment where one repeatedly asks someone to give evidence for all their opinions and generally insists on a bad faith debate
  • Mansplaining diatribe responses. If you plan to respond to a post in a way which naturally begins with some form of "Well actually", "To be fair" or similar, don't.
  • Playing Devil's Advocate. If a user wishes to have an argument based on the other side not believing what they are arguing, there are plenty of other avenues for doing so. Unless a Vatican Council opens an account here and requests public dialogue regarding someone's Beatification, your Devil's Advocate arguments are unnecessary. Have debates only based on your actual viewpoint.

Secure Communications

As noted above, neither leftist.network nor any other Mastodon instance should be considered secure communications. We recommend meeting other Leftists here, and then connecting via secure platforms if you wish to have a private discussion.

Text Communications

Main Recommendation: Briar

Briar is a secured End to End Encrypted messaging application for Android phones. It's available on Google Play Store, F-Droid, or directly.

Why Briar specifically? Because it offers decentralized messaging with or without internet. We strongly recommend reading their How it Works page

  • If you have internet access, Briar can connect directly to other users via the TOR internet anonymizing network
  • If you do not have internet, Briar can connect to local users via wifi or bluetooth
  • If you have a message for someone not locally available, Briar can send the message to others in your private group, and those messages can be couriered to the other person when your friend gets into their area

It works great for messaging each other currently, and will still work if you later find yourself trying to communicate with others without internet access, such as at a protest. Besides private messages, Briar supports private group messages, forums, and blog posts. Briar is essentially a better version of Firechat, the distributed messaging Hong Kong protesters used to communicate with each other. If you plan to communicate with others using Briar for a protest, it's recommended to have a copy of the apk to be able to give to others to install, such as connecting to each other's phones via USB, or passing it on a USB flash drive.

Secondary Recommendation: Signal

Signal is also encrypted messaging, and a secure platform for messaging. Unlike Briar, which is only available for Android, Signal is available for iPhone and Android. The reason Briar has our main recommendation is that it works both with and without internet, while Signal requires internet. If Briar doesn't entirely fit your needs, we recommend installing both Briar and Signal, and falling back to Signal when needed.

Video/Audio Communications: Jitsi Meet

Jitsi Meet is Open Source hosted videoconferencing software. On your laptop or desktop you can videoconference using only your browser with no extensions or installation. For mobile there is an easy app available for Android and iPhone

Note that while it is easy to have client to server encryption for Jitsi, using normal https ssl connections and the built-in encryption of WebRTC video, Jitsi calls are not End to End Encrypted. They are only as secure as the server being used for them, and how much you trust the owners of that server. While there is a Public Jitsi Server available, for confidential chats we'd recommend setting up your own server or using the server of someone you trust. It's extremely easy to setup, either from your house or a cheap web host.

  • Adding descriptive text to images

This instance has very much been inspired by and aims to follow the path of mastodon.social and their guidelines, which have been incorporated below:

  1. The following types of content may be removed without warning from the public timeline:

    3. Untagged nudity, pornography and sexually explicit content, including artistic depictions
    4. Untagged gore and extremely graphic violence, including artistic depictions

  2. The following types of content will be removed from the public timeline, and may result in account suspension and revocation of access to the service:

    1. Racism or advocation of racism
    2. Sexism or advocation of sexism
    3. Discrimination against gender and sexual minorities, or advocation thereof
    4. Xenophobic and/or violent nationalism

  3. The following types of content are explicitly disallowed and will result in revocation of access to the service, with or without notice, and any identifying information may be shared with the relevant authorities:

    1. Sexual depictions of children
    2. Content illegal in Germany and/or France, such as holocaust denial or Nazi symbolism
    3. Conduct promoting the ideology of National Socialism

  4. Any conduct intended to stalk or harass other users, or to impede other users from utilizing the service, or to degrade the performance of the service, or to harass other users, or to incite other users to perform any of the aforementioned actions, is also disallowed, and subject to punishment up to and including revocation of access to the service. This includes, but is not limited to, the following behaviors:

    1. Continuing to engage in conversation with a user that has specifically has requested for said engagement with that user to cease and desist may be considered harassment, regardless of platform-specific privacy tools employed.
    2. Aggregating, posting, and/or disseminating a person's demographic, personal, or private data without express permission (informally called doxing or dropping dox) may be considered harassment.
    3. Inciting users to engage another user in continued interaction or discussion after a user has requested for said engagement with that user to cease and desist (informally called brigading or dogpiling) may be considered harassment.
