An AI pair-programmer in your terminal.

Free and open source CLI coding assistant written in Go, powered by MiniMax-M2.5 via the opencode.ai API. Set OPENCODE_API_KEY, run apollo, and start delegating — get going in a minute.

• Interactive CLI: prompt, think, act — a tight terminal loop with ANSI colors
• Tool execution: the agent runs shell commands itself, chaining calls automatically — how tools work
• Built-in tools: ls, read, bash, edit — run manually anytime with a / prefix
• Diff previews: edits show a colorized unified diff before anything is applied
• Skills: /skill:<name> loads reusable agent workflows — how skills work
• Tab completion: autocomplete filenames mid-command, shell-style
• Markdown rendering: formatted answers via glamour, not raw dumps
• Debug mode: apollo -d prints the raw API request JSON
• One binary: go install and you are done — install guide
• Open source: MIT-licensed, source on GitHub — why it exists

• Install & run: go install github.com/HimanshuSardana/apollo@latest, set OPENCODE_API_KEY, run apollo — full quickstart
