Blink is a self-hosted platform for building and running custom, in-house AI agents.
# Add to your Claude Code skills
git clone https://github.com/coder/blinkBlink is a self-hosted platform for running AI agents that your team can talk to in Slack, GitHub, and a web UI. It includes Scout, an agent built for coding tasks and codebase research, which you can customize with new tools and prompts. You can also build entirely new agents in TypeScript with the Blink SDK.

npm install -g blink-server
blink-server
Open the Blink web UI in your browser and create your first agent. Alternatively, you may run the server with Docker.
Understanding complex codebases - ask questions about how a repo works, how parts connect, or where to start when the code is unfamiliar.
Coding partner in Slack - discuss ideas, open GitHub issues, or handle small coding tasks directly in Slack without breaking the conversation.
Customer support in shared channels - let your customers ask technical questions in shared Slack channels and get answers backed by citations from your codebase and documentation.
And more - Blink lets you build custom agents for any use case.

Agents are HTTP servers that respond to events. The Blink Server deploys them as Docker containers, routes messages from Slack/GitHub/web UI, and manages conversation state - your agent just defines how to respond.
import { convertToModelMessages, streamText } from "ai";
import * as blink from "blink";
const agent = new blink.Agent();
agent.on("chat", async ({ messages }) => {
return streamText({
model: "anthropic/claude-opus-4.6",
messages: convertToModelMessages(messages),
system: "You are a helpful assistant.",
});
});
agent.serve();
The on("chat") handler processes incoming messages. For tool calls, the server automatically loops back to your agent until the response is complete.

We've been using Blink at Coder for a few months now. We built in-house agents that:

That being said, Blink is still in early access. You may encounter bugs and missing features. If you do, please file an issue.
