Axtary vs PreFlight

Axtary 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.

Axtary

Axtary sits beside the agent and evaluates each tool call against deterministic policy before the underlying provider is called. Routine actions — ones that clear the policy rules — pass automatically. Higher-risk actions pause for a human to review the normalized payload, and the approval is cryptographically tied to that specific hash. If anything changes after sign-off, the adapter catches the mismatch and blocks execution. Every attempt, pass, and rejection lands in a verifiable ledger. The self-hosted path keeps provider credentials local, which matters for teams that cannot route credentials through a third-party service.

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.

Pros	Payload hash binding ties every human approval to the exact diff or message reviewed, so a payload altered after sign-off is rejected at the adapter before the provider is called — eliminating the attack surface where approval covers a summary rather than the literal content. Deterministic policy evaluation on routine actions means low-risk tool calls clear automatically, so human reviewers only see the calls that actually warrant attention rather than approving every agent action manually. Self-hosted policy enforcement keeps provider credentials local, so teams under data-residency or credential-exposure constraints can run authorization checks without routing sensitive tokens through a third-party service. A verifiable ledger records every decision, pass, execution result, and trace reference, so teams facing a post-incident audit have a timestamped, tamper-evident record of what the agent was authorized to do and what actually ran. ActionPass artifacts carry normalized action records — actor, intent, resource, constraints, and policy version — structured for consumption across SDKs and MCP wrappers, so teams can integrate authorization evidence into existing tooling without custom log parsing.	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	The hash-binding guarantee only holds for connectors that implement the adapter-side verification step. Teams whose agents call tools outside the documented connector set — anything not in the GitHub, Slack, Linear, AWS/GCP, MCP, or document-search list — must write and maintain their own adapter verification before Axtary's core security property applies to those calls. Axtary enforces policy on proposed actions; it does not generate, plan, or sequence agent tasks. Teams that need an authorization layer bundled with agent orchestration — where the same system routes tasks and enforces rules — will hit this ceiling immediately and look at platforms that combine both concerns. The product is in access-request stage with a small documented connector surface, which means teams with production timelines that cannot absorb an integration build or a waitlist delay will default to a more established policy enforcement tool rather than waiting for connector coverage to expand.	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

PreFlight is open source. Choose based on which difference matters most for your workflow.
