Coding / Reason

Reason

Autonomous coding agent that connects to GitHub, takes an issue, and opens evidence-backed pull requests with logs and screen recordings. Positions itself as cheaper per solved task than Codex while still usable from Mac, web, terminal or Slack.

If Reason isn't right

• Cursor in coding

  The editor most builders end up in: codebase-aware edits that actually land.

  Free tier; Pro from $20/mo

• Claude in coding

  My pick for anything long: contracts, big codebases, a messy brief. It reads carefully and says when it isn't sure.

  Free tier; Pro from $20/mo

• GitHub Copilot in coding

  Safe default for teams already on GitHub; strong autocomplete, solid chat.

  Free tier; Pro $10/mo

• Devin Desktop in coding

  Was Windsurf; Cognition rebranded it as Devin Desktop. Same IDE, now the command center for local and cloud coding agents. Update in-app and your settings stay put.

  Free tier; Pro from about $20/mo (legacy Windsurf plans carry over)
