Both fix what they find. Only one tests the fix.
DeepSource pairs 5,000+ static rules with Autofix AI. Codeward verifies suggested fixes in an isolated sandbox before showing them.
Unlike traditional AI review tools that spam pull requests with unverified comments, Codeward executes real tests inside isolated Firecracker microVMs before opening a fix. Only verified, non-breaking code reaches your repository (86.3% merge acceptance rate).
Use DeepSource if you want a polished, affordable code-health platform with unlimited one-click Autofix and support for GitHub, GitLab and Bitbucket. Use Codeward if you want sandbox-verified fixes, multi-agent analysis and the option to self-host for free.

DeepSource is a good value, widely supported across hosts, and its autofix is smooth. It is the safer choice if you use GitLab or Bitbucket today.
Codeward's differentiator is verification and breadth. If autofix suggestions that break tests worry you, a sandbox run before the suggestion appears matters.
DeepSource: restructured in Feb 2026 to a free Open Source plan, Team at about $24 per user per month with unlimited Autofix, and custom Enterprise. Codeward: open source.
No. DeepSource has more individual rules. Codeward has 122 checks that mostly use AI reasoning and real tools.
DeepSource claims under 5%. Codeward suppresses low-confidence findings with a deterministic policy and only blocks on high-confidence criticals. Test both on your repo.
There is no automated migration. Install both and compare on a live PR.
Autofix you can trust, because it was tested.
