  • 10+ providers supported
  • Switch models instantly
  • Bring your own API keys
  • Local models via Ollama

AI edits right in your code

See proposed changes as red/green inline decorations. Accept, reject, or modify each change individually. Never leave your editor.

  • Red/green diff decorations
  • Accept/reject per hunk
  • Streaming diffs in real-time
  • Works with any file type

Let AI handle the heavy lifting

QCoder's agent mode autonomously reads files, writes code, executes commands, and iterates until the task is complete. Like having a junior developer who never sleeps.

  • Multi-step task execution
  • File read/write operations
  • Terminal command execution
  • Iterative problem solving

Why QCoder

QCoder gives you full control over your AI-assisted development workflow. No middlemen, no subscriptions, no data you didn't choose to share.

Bring Your Own API Key

QCoder does not provide AI model access. You bring your own API keys from OpenAI, Anthropic, Google, or any other provider. That means unlimited usage at your own cost, with zero vendor lock-in. Switch providers any time without losing your workflow.

Run Local Models for Free

Connect to Ollama or LM Studio and run models entirely on your own hardware. No API key required, no data leaves your machine, and it costs nothing beyond the electricity. Perfect for offline work or sensitive codebases.

Free and Open Source, Not a Subscription

QCoder is free and open source under the MIT License. No monthly fees, no per seat pricing, no surprise bills. Read the code, build it yourself, and keep it forever.

Self-Hosted and Air-Gapped Ready

Your code never leaves your machine unless you explicitly send it to an API you control. Deploy on-premises, run behind a firewall, or operate in a fully air-gapped environment. QCoder works wherever your security policy demands.
