The free coding agent
Is freebuff safe? Promising trust profile, but some evidence still deserves review.
Compare freebuff
How does it stack up against its Coding Agents neighbours?
Pick any agent to compare →In detail: freebuff scores 56.3/100 (Grade C), ranked #812 of 1374 tracked open-source AI agent projects, on evidence coverage C (2 of 5 independent signal types). The public evidence: no package-provenance attestation found; OSSF Scorecard rates its supply-chain practices 3.4/10; recent commits are unsigned; last pushed 2026-11-05. Every point is earned from checkable signals — never paid placement. How scoring works →
What freebuff can reach, and who runs it
Checked 2026-10-06, each with its source. PUBLISHER is the company's or project's own statement, which we haven't verified; CHECKED is something we observed ourselves. These facts describe the product. They don't change its score.
Who runs it
- PUBLISHER Run by Freebuff, Inc., which also operates Codebuff.
Where your data goes
- PUBLISHER It collects prompts, code, files and repository data, which are processed by its own systems and by AI model providers.
- PUBLISHER It shows ads: prompts and messages may be analysed to select and measure them, including by deriving general interest categories.
- PUBLISHER It doesn't train models on your prompts or project data unless it says so before you use that model or feature.
Security practice
- CHECKED freebuff.com's security.txt lists [email protected]. The repository has a SECURITY.md; GitHub private vulnerability reporting is off.
How freebuff could raise its score
Each line changes one public signal and recomputes with the live scoring function. The gains don't add up exactly, because the score is capped near the top.

Chain of custody
Scanners check what the code says. This traces who ships freebuff and whether that has changed: from the source repository, through how changes are reviewed and released, to the code you run. These are the checks for OWASP ASI04 Agentic Supply Chain Vulnerabilities.
-
Source Unsigned
github.com/CodebuffAI/freebuff, Apache-2.0, last pushed 2026-11-05. None of the last 100 commits carry a verified signature, so no change traces to a verified identity.

Verify this score yourself
Every build re-issues freebuff’s score as an Ed25519-signed credential, valid for 7 days. You can check it offline against HVTracker’s published key; if anyone changes a number after signing, verification fails.
What this score doesn’t check
It covers who ships the code, not what the code does. It doesn’t read tool descriptions or prompts for injected instructions, watch runtime behaviour, or find bugs nobody has disclosed yet. For that, run a content scanner before you connect it, such as Cisco MCP Scanner or Snyk Agent Scan.

Quick Trust Read
How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade C reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage C is separate — it grades how many independent signal types back the score (2 of 5), so a high score on thin evidence stays visible. Full methodology →

Are freebuff's commits signed?
Not a safety endorsement. HVTracker describes what public signals show, not whether a project is safe for your use case. Run your own security review before adopting in production.

MCP, providers, tool surface
These runtime-trust fields — detected from public repo docs and manifests — contribute a bounded adjustment to this project's HVTrust score alongside supply-chain evidence.

Detected changes to freebuff's runtime surface and supply-chain posture, from daily public-signal snapshots. A change here means our detectors see something different — a genuinely changed capability, or better evidence of an existing one.
Maintain freebuff?
For maintainers
HVTrust scores freebuff from public signals only — we never contact maintainers first. If a signal is wrong, stale, or missing (provenance you publish, a Scorecard you run, signed releases), tell us and we'll review it. Corrections are public and tracked on GitHub.
