CodeAnt AI scans for quality and opens fixes. Codeward executes and validates every patch in a sandbox.
CodeAnt AI is an automated code review and security autofix platform. Codeward provides an 8-agent guardian pipeline that executes PRs in sandboxes and verifies fixes before suggesting 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 CodeAnt AI if you want proprietary automated code quality and security scanning with automatic remediation PRs. Use Codeward if you want a 100% open-source, sandbox-verified platform that prevents diff hallucinations, detects flaky tests via 10× reruns, and enforces 122+ AST-based security, debt, and compliance rules.

CodeAnt AI focuses on automated quality and autofixing code smells. For teams wanting an out-of-the-box SaaS scanner to find known patterns and open automated pull requests, it provides a clean workflow.
The risk with unverified autofixes is hallucinated fixes that look correct on paper but fail tests or introduce subtle regressions at runtime. Codeward solves this with isolated sandbox execution: every patch is built and tested in a microVM before a diff is ever recommended to developers.
Furthermore, Codeward is fully open-source under Apache 2.0, giving engineering leaders complete data privacy and freedom from vendor lock-in.
CodeAnt AI: Proprietary SaaS pricing with custom tiers. Codeward: Free self-hosting under Apache 2.0; managed cloud with free tier at codeward.cloud.
Codeward executes code in real microVM sandboxes, verifies that fixes actually pass tests before proposing them, detects flaky tests, and is 100% open-source.
Yes. Codeward generates suggested diffs and fixes, but unlike unverified AI tools, Codeward tests the fix inside an ephemeral sandbox first to ensure it doesn't break your build.
Yes. Because Codeward is open source, you can deploy the orchestrator, API, and sandboxes inside your own infrastructure.
Don't guess if a fix works. Verify it.
