Devin and Fixa.dev are both AI tools that automatically handle coding tasks, but at very different scales and price points. Fixa.dev automatically detects and fixes code quality issues as an automated pipeline step. Devin is a fully autonomous AI software engineer that handles complete development tasks from reading an issue to opening a pull request. One automates code quality; the other automates the full engineering workflow.
Devin
Devin is Cognition AI's autonomous AI software engineer. It reads GitHub issues, plans solutions, writes code across files, runs tests, browses documentation, and opens PRs in an isolated sandbox - all without supervision. It is priced at $500/mo for engineering teams that want to delegate complete development tasks to an autonomous AI agent.
Fixa.dev
Fixa.dev uses AI to automatically detect and fix bugs and code quality issues across multiple programming languages. It integrates into development workflows as an automated improvement layer - scanning code and applying fixes without requiring manual review of each problem. A free tier is available; detailed pricing is not clearly published.
Key Differences
- Scope: Devin handles complete software engineering tasks from issue to PR. Fixa.dev handles code quality fixes within existing code.
- Cost: Devin starts at $500/mo. Fixa.dev has a free tier.
- Autonomy type: Devin plans and builds new functionality autonomously. Fixa.dev automatically fixes quality issues in existing code.
