DeepSource
DeepSource is an AI code review platform combining over 5,000 deterministic static analysis rules with AI review agents, covering security, quality, complexity and coverage. It includes SAST, SCA, IaC security and Autofix, and the site states DeepSource has joined Harness.
- Hybrid design uses each method where it is strong instead of picking a side
- Deterministic rules give a gate that can be trusted to be consistent
- AI agents catch reasoning defects no pattern can express
- False positives named as the explicit enemy rather than an accepted cost
- Cannot find runtime, load-dependent or integration defects at all
- No visibility into business logic correctness, only into code correctness
- Architectural problems remain invisible to file-level inspection
Sourcery
Sourcery is an AI code-review tool that reviews every pull request in minutes, catching bugs, edge cases and security issues with one-click fixes, plus codebase security scanning, with a strong stance on keeping your code private.
- Takes the first-pass review off a stretched team
- Explains findings and writes committable fixes
- Adds lightweight security scanning beyond the diff
- Clear, auditable code-privacy posture
- Not a replacement for human review judgement
- Early false positives need tuning out
- Most valuable at real PR volume, not for solo use
