Codacy
Codacy combines static analysis, SAST, SCA, secret scanning, IaC checks and test coverage in one platform, and has repositioned around AI-assisted engineering — detecting AI policy violations and unapproved model calls, with Codacy Guardrails embedding checks inside agentic workflows.
- Correctly identifies that automated review becomes the primary control once agents write the code
- Unapproved model call detection is a genuinely new and obviously necessary check
- One platform and one findings list beats four scanners developers have learned to ignore
- Guardrails catches problems while an agent works rather than after it commits
- Supported languages are not enumerated anywhere on the pages we read
- No false positive rates are published, and noisy inline warnings get disabled permanently
- More automated checks mean more findings, which is how teams learn to ignore them
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
