Agents

Anthropic's agentic coding tool. Lives in the terminal, reads and edits your repo directly, and takes instructions from a CLAUDE.md file you write.

OpenAI's open-source terminal agent. Runs locally in a sandbox, with cloud delegation for longer tasks.

A VS Code fork built around AI. Inline completion, chat over your codebase, and a background agent — all in one editor.

The incumbent. Completion, chat and an agent mode across VS Code, JetBrains, Visual Studio and github.com.

Open-source pair programming in your terminal. Git-native: every change lands as a commit.

Open-source autonomous agent inside VS Code. Plan mode first, then act — with approval on every step.

An agentic editor built around Cascade — a flow that keeps working across files without being re-prompted each step.

Google's open-source terminal agent, with a notably generous free tier for individual developers.

Open-source autonomous software engineer. Runs in a container, can be self-hosted entirely.

A fully autonomous agent you assign tickets to. It works in its own cloud environment and opens PRs.

Sourcegraph's agent, built on the assumption that unlimited reasoning beats careful token budgeting.

Block's open-source, on-machine agent. Extensible through MCP, works with any model.

An open-source VS Code agent with custom modes — you define the personas and what each may touch.
