slack-summarizer
Reads a day of messages from a public Slack channel and posts a digest written by an OpenAI model. You supply the API key, so the model calls are billed to you.
Runs on Slack
Every listing whose runtime names Slack. Derived from the records on this site, not curated.
slack-ruby-client
A Ruby client for Slack's Web and Events APIs, with a command-line tool alongside it. It is a client library, not a bot.
slack-cli
A Slack command-line client written in bash: post richly formatted messages, upload files, and pipe output straight into a channel. A CLI, not a bot.
slack-bot
A Slack bot for development teams: start a Jenkins job, watch a Jira ticket or a pull request, and run your own macros and cron commands from chat.
secret-santa
Draws Secret Santa names for a Slack, Discord or Webex channel and messages each person their match. The authors run it as a hosted service; this is the code behind it.
sactive-bot
A chat bot framework descended from Hubot, with adapters for Slack, Microsoft Teams, Mattermost and WeChat. It is a framework, not a bot.
response
Monzo's incident-response tool: a Slack bot opens a channel for an incident, tracks who is doing what, and turns the whole thing into a written report afterwards.
replbot
Gives a Slack or Discord channel a live shell or language REPL, each session running in its own container. Handing chat members a shell is exactly as dangerous as it sounds.
open-source-slack-ai
A Slack bot that summarises a channel or a thread on demand, self-hosted. Its own README gives the reason: the official Slack AI product has limited access and add-on pricing. It calls a hosted model, so the token bill is yours.
myGPTReader
A Slack bot that reads a web page, a PDF or a YouTube transcript you hand it and answers questions about the contents through OpenAI's API. You supply the API key, and the model calls are billed to you.
langchain-experiments
A set of Jupyter notebooks working through LangChain: a YouTube-transcript search index, FAISS similarity queries, and a Slack bot built on top. Teaching material, not a product.
jbot
A Java framework for writing Slack and Facebook Messenger bots: it supplies the event plumbing and conversation handling, and you write the replies. It is a framework, not a bot.
hubcommander
A Slack bot Netflix built for running GitHub organisation chores from chat — repository creation, permissions, org membership — behind its own approval steps.
goclaw
A Go rewrite of OpenClaw: one binary that fronts many LLM providers and runs teams of agents across Discord, Slack and other channels, with tenants kept apart in Postgres.
dsh-im
Puts a DeepSeek Harness agent behind your chat accounts: a message arriving in Feishu, WeChat, DingTalk, QQ, Slack, Telegram, Discord or WhatsApp is handed to the agent you are already running, and the reply comes back in the same thread. It connects an agent you supply; it is not the agent.
dorabot
A macOS desktop app that runs a long-lived AI agent with its own IDE workspace and connects it to WhatsApp, Telegram and Slack.
Openaibot
A chat bot that puts GPT-class models behind Telegram, Discord, Slack and Kook accounts, with tool calls and a plugin system. Its README says “This project is not abandoned, just no new features are planned”, which we read on 2026-09-13.
LangBot
A self-hosted platform for putting an LLM behind a chat account on many networks at once — Discord, Slack, Telegram, LINE, QQ, Feishu, DingTalk, WeChat, Matrix — with plugins and a knowledge base. Most of its documentation is in Chinese.
