What is Blocks?

Blocks is a platform that brings coding agents into your development workflow and external tools such as Slack, GitHub, and Linear. Mention @blocks and coding agents of your choice will help you with:
  • Writing and reviewing code
  • Fixing bugs and implementing features
  • Analyzing codebases and answering questions
  • Creating documentation
  • Managing tasks across multiple repositories
  • Creating projects and tickets
  • Status updates across GitHub, Slack, and Linear
  • And much more

​
How It Works

  1. Mention @blocks in any GitHub issue, PR, Slack message, or Linear ticket
  2. Describe what you need in natural language
  3. Get instant help from coding agents that understand your codebase
  4. Track progress through real-time updates and links to the Blocks dashboard
Blocks automatically understands the context of your request, accesses the relevant repositories, and provides intelligent assistance.

​
Key Features

Multi-Platform

Works seamlessly across GitHub, Slack, and Linear—mention @blocks anywhere your team collaborates.

Multiple Coding Agents

Choose from multiple agents including Claude Code, Codex, OpenCode, and Sisyphus. Each agent has unique strengths.

Multi-Repo Support

Plan Mode

Collaborate with AI on implementation plans before code changes are made.

Custom Commands

Create reusable prompts and workflows for common tasks your team performs.

Serverless Execution

No infrastructure to manage—everything runs automatically in response to your mentions.

​
Quick Workflow Example

Here’s a typical workflow with Blocks: 
You in GitHub: "@blocks fix the authentication bug in the login flow"
Blocks: 👀 (acknowledges your request)
Blocks: [Dashboard Link] I'm investigating the authentication issue...
Blocks: Found the issue in src/auth/login.ts:45 - the token validation is incorrect
Blocks: [Creates PR] Fixed authentication bug by updating token validation logic

​
