DeepSource vs Hostile Review
An honest comparison. Automated code quality with AI autofix meets adversarial AI auditing with 108 hostile agents.
DeepSource is an automated code quality platform — 5,000+ deterministic rules plus an AI review agent that catches bugs, anti-patterns, and security issues, then auto-generates multi-file fix PRs. Trusted by 3,700+ companies.
Hostile Review is an adversarial code audit — 108 specialized AI agents that assume your code is broken and prove where. Broader scope, deeper hostility, on-demand.
| DeepSource | Hostile Review | |
|---|---|---|
| Approach | 5,000+ rules + AI review agent + autofix | Adversarial multi-agent AI audit |
| AI Agents | 1 AI reviewer + deterministic rules | 108 specialized across 14 categories |
| Auto-Fix | ✓ Multi-file PRs via Autofix | Remediation guidance (no auto-PRs) |
| When It Runs | Every commit, continuous | On-demand scans |
| Pricing | Free (public repos) + ~$15–19/user/mo | Pay per scan, no seats |
| Free Tier | ✓ Public repos free | ✓ Demo scans (20 files) |
| Git Integration | GitHub, GitLab, Bitbucket, Azure DevOps | GitHub repos, zip upload, paste |
| Languages | 10+ (Python, JS, Go, Java, C++, Rust...) | Any (AI-reasoned) |
| Scope | Code quality + security + performance | 14 categories including compliance, AI, a11y, cloud |
- Hybrid detection — 5,000+ deterministic rules for precision plus an AI agent for nuanced review. Best of both approaches
- Autofix PRs — automatically generates multi-file pull requests that fix detected issues, not just flag them
- Zero CI dependency — can analyze repos without requiring CI pipeline changes. Connect and scan
- Continuous scanning — every commit is analyzed automatically. Issues are caught the moment they're introduced
- Multi-repo dashboard — unified view of code health across all your repositories
- Developer-friendly — free for public repos, fast setup, clean interface. Built for developers, not security teams
- Performance detection — catches anti-patterns, dead code, and performance issues alongside security and quality
- 108 specialized agents vs 1 — each agent attacks from a different angle, then findings are deduplicated and consensus-ranked
- 14 review categories — goes far beyond quality and security: compliance (GDPR/HIPAA/PCI), AI security, accessibility, i18n, cloud infrastructure, data pipelines
- Cross-file attack chains — finds vulnerabilities that span multiple files and components, where the issue isn't in any single file
- Business logic vulnerabilities — catches flaws in application logic that no deterministic rule can detect
- Adversarial mindset — agents assume hostile intent. They're trying to break your code, not improve it
- No per-seat pricing — one scan costs the same whether you have 2 developers or 200
- Granular control — choose which agents, which quality tier, which files. See the cost before you scan
