ComplyEdge vs PreFlight

ComplyEdge and PreFlight are both guardrails & safety tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

ComplyEdge

ComplyEdge is an open-source compliance engine that runs on every production request your AI agent processes, enforcing EU AI Act Article 5 prohibitions and emitting structured audit trails instead of opaque scores. The decorator-based Python SDK wraps agent entry points with a single annotation, so enforcement is tied to the code path rather than bolted on downstream. TrustLint, the companion CLI tool, moves the same rule set into CI/CD so violations surface before deployment. The ceiling appears when you need jurisdictions beyond EU or rule sets beyond Article 5 — the repo shows EU coverage, and teams with broader regulatory scope will find themselves extending the rule library themselves. With three GitHub stars and zero open issues at time of writing, production battle-testing is still accumulating.

PreFlight

PreFlight installs via npm and runs as a pre-commit gate, scanning AI-generated code for security vulnerabilities in auth flows, database logic, and SQL patterns — then offering deterministic or AI-assisted patches inline. It integrates with VS Code, Cursor, and MCP clients, so the scan happens in the environment where the AI code was written. The free tier caps patches at ten, which is sufficient for evaluation but stops short of daily use on an active codebase. Teams that exceed that ceiling without a pro key lose the fix-application step and are left with scan output only. The repo is open-source and self-hosted, so the scan never phones home.

Platforms	Python	CLI, npm, VS Code, Cursor
Pros	Explicit rule ID and article citation on every blocked request, so your audit trail holds up to regulatory scrutiny rather than requiring post-hoc interpretation of a score. Decorator-based enforcement wraps agent functions at the code level, which means compliance logic travels with the function through refactors and deployments rather than depending on a separate sidecar being configured correctly. TrustLint CLI enables offline compliance scanning in CI/CD pipelines, so Article 5 violations are caught before deployment rather than discovered when a production request gets blocked. Apache-2.0 license and self-hosted execution mean no request data transits a third-party service, which removes a class of data-handling objections from security reviews in regulated industries. Provider and rules directories are structured as separate extension points, so teams can add custom rule files without forking the core engine — though that means writing and maintaining rule logic in-house.	Runs entirely locally with no cloud dependency for scanning, so code never leaves the machine during the security check — which matters for teams under data-residency or compliance constraints. Pre-commit integration means vulnerabilities surface before they enter the repository rather than at PR review, so the team avoids the back-and-forth of post-commit security findings. RLS and SQL safety checks are explicitly scoped, so the specific class of vulnerability that AI tools most often miss in database logic gets dedicated coverage rather than a generic lint pass. MCP client support lets other tools and editor workflows invoke the scanner directly, so the security gate can be embedded in automated flows without requiring a separate manual step. Open-source codebase allows teams to audit the scan rules themselves, so trust in the tool does not depend solely on vendor claims about what it detects.
Cons	Rule coverage confirmed in the repo is EU AI Act Article 5. Any team with compliance obligations that extend to GDPR, CCPA, the EU AI Act's Articles 6-51, or sector-specific frameworks has to author and maintain the additional rule files themselves — at which point ComplyEdge becomes rule infrastructure, not a compliance solution. The Python SDK is the only documented language binding. Teams running agents in Node.js, Go, Java, or any other runtime have no supported integration path and would need to implement REST or subprocess wrappers around the engine, adding a maintenance layer with no upstream support. With three GitHub stars and no community-contributed rules or issues in the public repo, the rule library reflects the maintainer's interpretation of Article 5 rather than one tested across adversarial inputs from a broad user base. Teams in high-stakes regulatory environments will want independent legal review of the rule definitions before relying on them in filings — and any team that needs a vendor-supported, contractually backed compliance guarantee will move to a commercial compliance platform instead.	The free tier caps patch application at ten — once that limit is hit, the tool continues to surface findings but stops applying fixes. A team using AI coding tools daily will exhaust this on a single feature branch, forcing a licensing decision before they have enough production signal to evaluate the tool's accuracy. The scanner is scoped to auth, database, and SQL vulnerability classes. Teams that need coverage across a broader attack surface — dependency vulnerabilities, secret detection, SSRF, or injection beyond SQL — will need a separate tool running in parallel, which means maintaining two scan configurations and reconciling their output. The project shows a single star and no forks on GitHub at the time of curation, with an open issue logged. Teams evaluating this against established SAST tools with large community rule sets and documented false-positive rates will find precious little external evidence of production use — which is the condition under which a security-conscious team switches to a competitor with a longer track record.

Bottom line

Only ComplyEdge exposes a public API. Choose based on which difference matters most for your workflow.
