Contribution Guide

This is the contribution guide for developers wanting to help out with Revolt.

Please first read our GitHub contributors guidance.

Backend (Rust)

The backend can be quite demanding at times, it is recommended that you have:

  • A modern multi-core CPU for Rust compilation.

  • About 30gb of free disk space to ensure everything can be installed and built.

    Tip: run cargo clean semi-frequently to delete old build artifacts.

  • At least 4gb of free memory.

    • Roughly half a gigabyte to run the Revolt stack
    • Betweeen 2-12gb to run Visual Studio Code with rust-analyzer
    • About 1gb to run a browser

You need the following prerequisites:

  • Rust (ideally through rustup)
  • Docker
  • Git
  • mold (optional but recommended, see mold)
  • If you'd like to run revite:
    • Node.js (v16 at minimum)
    • Yarn (enable corepack)

Please refer to the technical documentation found here.

Now you are ready to follow the development guide.

Frontend (Typescript)

You need the following prerequisties:

Please refer to the technical documentation found here.

Now you are ready to follow the development guide.

You should aim to test your changes on:

  • A Chromium browser (e.g. Chrome or Edge)
  • A WebKit browser (e.g. Safari or Epiphany)
  • Firefox

Other ways to help

You can contribute to Revolt in a variety of ways:

1. Feedback

The easiest, but most important, way to contribute to Revolt is to voice your opinion and give us feedback. We want to hear what you think and appreciate and await your feature suggestions, bug reports and general opinions on everything Revolt has to offer.

Within the Revolt app, you can navigate to the feedback tab, or you can open an issue on the relevant GitHub repo.

2. Translate

Revolt is used by users all around the world; as such, it's more accessible if the user interface is available in a variety of languages. You can contribute translations through Weblate.

3. Donate

Revolt is not backed by a big company, is not currently monetised (for example, via a subscription service) and does not serve you advertisements; as such, Revolt currently relies entirely on donations. You can learn more about donating here - if you want to make a larger donation, please consult me first.

Frequently Asked Questions

This page includes several frequently asked questions and explanations.

All of these answers are written from the perspective of the project owner.

Last Update: 10th May 2024

Why another project?

I think this is best explained with a bit of history:

  • Revolt started as a passion project
  • It grew way beyond any of our expectations
  • We might as well keep going since there is an interest in this space

Beyond that:

  • Revolt has been a great learning experience, including development, management, and running the infrastructure for a large project. Revolt has also taught me a lot about different concepts and programming languages, and really, that's how developers learn. We make cool projects to try to better how we work, it doesn't matter if someone has done it before as long as you can attempt to do the same. Reinventing the wheel is part of the process.
  • At the time, there was also a relative void of competition in this specific genre of chat platforms. There were Guilded, Discord, and Matrix but these are all either closed-source or cater to a different audience.

PS. I've had a few people say, 'why not just contribute to X?', the answer is quite simple, I just didn't know about any of these projects (i.e. Matrix).

How are we funded?

Revolt is entirely funded through donations, we have amassed a significant amount of money from donations alone. (financial transparency reports coming soon :tm:)

The month-to-month income of Revolt covers our operational costs and leaves enough spare to cover yearly expenses and the occassional one-time expense, such as for additional hardware.

We have monetisation plans lined up for the future, however it is not our intention to paywall existing features, instead where possible we intend to pass down costs such as for file storage or voice bandwidth.

'X' feature when?

Please take a look at our roadmap on GitHub.

If you find something is not listed, it could be being worked on somewhere or have been requested as a feature.

Does Revolt have federation?

As of right now, Revolt does not feature any federation and it is not in our feature roadmap.

However, this does not necessarily mean federation is off the table, possible avenues are:

  • Implement our own federation protocol
  • Implement a promising up and coming federation protocol, polyproto
  • Implement the Matrix protocol (unlikely, obtuse and unstable)
  • Implement the XMPP protocol (battle-tested and stable)

Any federation that is implemented MUST exercise caution in:

  • Preventing spam and abuse: moderators should be able to block malicious actors
  • Protecting user data: users should be able to redact all of their information and messages

What can I do with Revolt and how do I self-host?

In general:

  • The Revolt branding is used to represent the platform,
  • You may use the branding as-is to promote the platform and your community on the platform.
  • You should not use the branding in order to appear as if you are associated with the Revolt team.
  • Please make explicit distinctions between Revolt (the platform, "") and the Revolt software.
  • The Revolt software is unbranded and only associated by name.

If you have any concerns or questions, please liase with us at

As a third-party platform:

  • You must provide correct attribution in line with our software licenses:

    If you are using official images (GitHub Packages / Docker Hub), attribution is included. If you are modifying the software and using it in production, you must publish the changes to the source publicly in line with AGPLv3. (In addition to providing attribution back to the original project.)

  • You are solely responsible for whatever happens on your third party instance, we provide no warranty or liability for what happens on 3rd party instances.

  • You must not appear to associate with Revolt / unless if granted explicit written permission. In regards to custom clients, provide a warning of any potential risks or clear it with us.

  • You may not use any of the Revolt branding or brand assets to advertise or promote your third party instance.

You can self-host Revolt by:

Can you verify my server/bot?

Currently, you can only apply to verify servers given that you have a valid reason to believe verification is necessary for your community. Verification is intended to provide protection for server owners from copy cats and to provide authenticity to users as such we are not just giving it out to anyone because that would defeat the purpose.

However if you would like to get a server verified, you should satisfy one of the following criteria:

  • Official community for a well-established open source project

  • Official community for any other well-established product, service, or person

  • Large and active distinct pre-existing community

    Distinct means the community is unique and well-known (& has an active presence) off platform. This means we are not currently verifying generic servers that centre around a topic unless if it meets one of the first two criteria. Though in special circumstances, well known on platform communities may also be considered.

Server verification also comes with a vanity invite, so please have one ready if you want to apply. To apply, drop an email at

We also periodically prune verification from servers that have fallen into disrepair and / or otherwise are no longer active.

For questions about the Revolt platform, you may want to go to our knowledge base:


You can connect to the API on the following URLs:

https://api.revolt.chatProductionPrimary API endpoint endpoint for old client endpoint for new client

You can connect to the events server on the following URLs:

wss://ws.revolt.chatProductionPrimary events endpoint endpoint for old client endpoint for new client


To authenticate with the API, you must first acquire a bot token or user token:

  • Bot: create one from user settings in the client
  • User: copy one from client or authenticate manually through API

Then you may provide these through either:


When dealing with an authenticated route.

Rate Limits

Revolt uses a fixed-window ratelimiting algorithm:

  • You are given a set amount of calls per each named bucket.
  • Any calls past this limit will result in 429 errors.
  • Buckets are replenished after 10 seconds from initial request.


There are distinct buckets that you may be calling against, none of these affect each other and can be used up independently of one another.



There are multiple headers you can use to figure out when you can and cannot send requests, and to determine when you can next send a request.

X-RateLimit-LimitnumberMaximum number of calls allowed for this bucket.
X-RateLimit-BucketstringUnique identifier for this bucket.
X-RateLimit-RemainingnumberRemaining number of calls left for this bucket.
X-RateLimit-Reset-AfternumberMilliseconds left until calls are replenished.

Rate Limited Response

When you receive 429 Too Many Requests, you will also receive a JSON body with the schema:

interface Response {
  // Milliseconds until calls are replenished
  retry_after: number;


Revolt's permission system works by sequentially applying allows then denies.

Flow Chart

Below are the high-level steps taken to determine both server and channel permissions (click to view).

If you are looking to implement permissions in a library, I highly recommend reading either revolt.js or delta source code since all the routines are well commented and should be relatively easy to understand.


The following permissions are currently allocated:

ManageChannel11 << 0Manage the channel or channels on the server
ManageServer21 << 1Manage the server
ManagePermissions41 << 2Manage permissions on servers or channels
ManageRole81 << 3Manage roles on server
ManageCustomisation161 << 4Manage emoji on servers

Uploading Files

File uploads work by first sending a file to the server and then using the ID provided.

You can find out what kinds of files you can upload by visiting This may depend on your instance, so you should determine the endpoint from the root API response.

To upload a file, pick the desired tag then send a POST to {endpoint}/{tag} along with a multipart/form-data body with one field file that contains the file you wish to upload.

You will receive the following JSON response:

  "id": "0"

You can use the ID wherever a file is required in the API.

Serving images

For caching purposes, use the following URL templates for file previews:


Parameters may be forced in the future. Missing URLs to be added.


You can find the API changelog on the releases page on GitHub!

Legacy Changelog

Gap in data

This is missing stuff between the one above and the one below.

20230120-1: New Account Events

This update adds two new events:

  • UserPlatformWipe { user_id: String; flags: Int; }
  • Auth { event_type: 'DeleteSession' | 'DeleteAllSessions'; [..] } (see Auth)

It also adds a new user flag of value 8 which represents a user who has been flagged and removed as spam.

It also adds one REST routes:

  • GET /users/<user_id>/flags: Fetch user flags

If your account is disabled, login will no longer throw an error, instead it will return Disabled { user_id: String } with status code 200.

You must now also specify a list of reactions when enabling restrict reactions.

20220903-1: Changes to role colours, masquerades, members and user timeouts

Role colours now support most valid CSS gradients and colours up to 128 characters and which satisfy the following Regex:

(?i)^(?:[a-z ]+|var\(--[a-z\d-]+\)|rgba?\([\d, ]+\)|#[a-f0-9]+|(repeating-)?(linear|conic|radial)-gradient\(([a-z ]+|var\(--[a-z\d-]+\)|rgba?\([\d, ]+\)|#[a-f0-9]+|\d+deg)([ ]+(\d{1,3}%|0))?(,[ ]*([a-z ]+|var\(--[a-z\d-]+\)|rgba?\([\d, ]+\)|#[a-f0-9]+)([ ]+(\d{1,3}%|0))?)+\))$

You can now also masquerade role colours per-message, simply include the colour property matching the properties above.

All members now include a joined_at property which indicate when the timestamp at which they joined a certain server.

All members now also have a timeout property which can be changed by PATCH /servers/<server_id>/members/<user_id>, users will not be able to interact with the server until the time expires. A visual indicator will also display on the user's end as well as for others in chat:

Timeout UI

20220901-1: Reactions Update

This update adds support for message reactions, including the following REST routes:

  • PUT /channels/<id>/messages/<id>/reactions/<emoji>: Add reaction to message
  • DELETE /channels/<id>/messages/<id>/reactions/<emoji>: Remove reaction from message
  • DELETE /channels/<id>/messages/<id>/reactions: Remove all reaction from a message

It adds a new permission React with value 536870912.

It adds three new events:

  • MessageReact { id: String; channel_id: String; user_id: String; emoji_id: String; }
  • MessageUnreact { id: String; channel_id: String; user_id: String; emoji_id: String; }
  • MessageRemoveReaction { id: String; channel_id: String; emoji_id: String; }

20220707-1: Emoji Update

This update adds support for server emojis, including the following REST routes:

  • GET /custom/emoji/<id>: Get an existing emoji
  • PUT /custom/emoji/<id>: Create a new emoji (uses Autumn id)
  • DELETE /custom/emoji/<id>: Delete an emoji
  • GET /server/<id>/emojis: Fetch all emoji in a server

It adds a new permission ManageCustomisation with value 8.

It includes a new field in the Ready payload: emojis?: Emoji[].

It adds two new events:

  • EmojiCreate(Emoji)
  • EmojiDelete { id: String }

20220608-1: Friends API v2

To accomodate the new Unicode usernames, the existing add friend route is being split into two different routes:

  • PUT /users/{target}/friend: Accept friend request where {target} is an ID
  • POST /users/friend: Send friend request (with body { username: string })

The old route will stop accepting usernames in a week, see 20220608-2.

20220608-2: 'Send Friend' Deprecation

The PUT /users/{target}/friend route will stop accepting usernames in place of {target}.

Establishing a connection

To get started, you should have:

  • A WebSocket URL, which is found from the API root.
  • A valid session or bot token.

You may authenticate in one of two ways:

You should listen out for Error events to find out if your credentials are incorrect or if something goes wrong here.

After authenticating, the server will respond with Authenticated then it will send a Ready event containing useful data.

The server will now start sending relevant events as they come in.

You should Ping the server every 10 to 30 seconds to prevent your connection being dropped.

Query Parameters

The Bonfire service supports additional query parameters:

versionDescribes the protocol version in use.1No †
formatIn what format to send packets, default is JSON.json, msgpackNo
tokenSession token for authenticating the connecting user.No

version may become compulsary in the future, please set it to 1 if you can.

You may specify these in the connection URL: wss://


This page documents various incoming and outgoing events.

Help Wanted: we should adopt AsyncAPI to properly document the protocol!

Plugin API


This page documents the old Revite Plugin API (manifest v1), it will be replaced in the new client.


The Plugin API is very powerful. Tread carefully.

Zero guarantees or sandboxes are provided. Your code is run as-is.

This document details the very experimental plugin API available in Revite.

This is more or less a proof of concept but can be used to achieve some simple client modifications.

Plugin Manifest

Below is the specification for revision 1 of the plugin API. The format parameter is not currently enforced but you should set it to 1 to avoid future breakage.

type Plugin = {
   * Plugin Format Revision
  format: 1;

   * Semver Version String
   * This is the version of the plugin.
  version: string;

   * Plugin Namespace
   * This will usually be the author's name.
  namespace: string;

   * Plugin Id
   * This should be a valid URL slug, e.g. cool-plugin.
  id: string;

   * Entrypoint
   * Valid Javascript code. It must be a function which returns a object.
   * ```typescript
   * function (state: State) {
   *   return {
   *     onUnload: () => {}
   *   }
   * }
   * ```
  entrypoint: string;

   * Whether this plugin is enabled.
   * @default true
  enabled?: boolean;

An example plugin:

    format: 1,
    version: "0.0.1",
    namespace: "insert",
    id: "my-plugin",
    entrypoint: `(state) => {
        console.log('[my-plugin] Plugin init!');
        return {
            onUnload: () => console.log('[my-plugin] bye!')

Using the Plugin API

To begin, you can load plugins using the global plugin manager at state.plugins.

Open the developer console and run:

state.plugins.load({ ... });
// ...where [...] is your plugin manifest as described above.

Plugin API

A plugin's entrypoint is required to return an object which is referred to as the instance:

interface Instance {
  onUnload?: () => void;

The Plugin API (state.plugins) exposes the following methods:

interface PluginAPI {
   * Add a plugin
   * @param plugin Plugin Manifest
  add(plugin: Plugin);

   * Remove a plugin
   * @param namespace Plugin Namespace
   * @param id Plugin Id
  remove(namespace: string, id: string);

   * Load a plugin
   * @param namespace Plugin Namespace
   * @param id Plugin Id
  load(namespace: string, id: string);

   * Unload a plugin
   * @param namespace Plugin Namespace
   * @param id Plugin Id
  unload(namespace: string, id: string);

   * Reset everything
