About Banana Code
Banana Code is a mobile AI coding agent. Pick a GitHub repo, describe the changes you want in plain English, choose any LLM model, and get a pull request with working code. All from your phone. HOW IT WORKS 1. Connect your GitHub account 2. Select a repository (public or private) 3. Type what you want changed ("Add error handling to the payment module") 4. Pick a model (ANY model!) 5. Watch the agent work in real time 6. Review the PR and merge when ready The agent clones your repo, creates a branch, makes changes across multiple files, and opens a pull request. Sessions run on a dedicated server, so you can close the app and come back later to get your PR. BRING YOUR OWN KEY Unlike tools that lock you into one model at $20+/month, Banana Code lets you use your own API key from OpenRouter, Anthropic, or OpenAI. Sign in with your ChatGPT subscription and use models you already pay for. The app is just $5/month. FEATURES - Any LLM model via OpenRouter (hundreds of options with live pricing) - Real-time streaming so you can watch the agent think and code - Full GitHub integration: clone, branch, commit, push, and PR creation - Attach screenshots to give the agent visual context - Session history with full conversation logs - Supabase integration (beta): run SQL, inspect schemas, write migrations - Dark theme with zero distractions YOUR CODE STAYS YOURS Repos are cloned to a temporary workspace and deleted after each session. API keys are encrypted at rest using device-level secure storage. You can revoke GitHub access or delete your account and all data at any time from Settings. AI-generated code should always be reviewed before merging. Banana Code is a tool for developers, not a replacement for code review. REQUIREMENTS - GitHub account (free) - API key from OpenRouter, Anthropic, or OpenAI (pay-per-use, typically pennies per session) - Internet connection required SUBSCRIPTION - $5/month after a 3-day free trial - Cancel anytime from Settings or your Apple ID subscriptions - Payment charged to Apple ID account at confirmation of purchase - Subscription auto-renews unless cancelled at least 24 hours before the end of the current period Privacy Policy: https://bananacode.ai/privacy Terms of Service: https://bananacode.ai/terms
