💳 Stripe Webhook & Checkout Doctor

by JustHandled Labs

$25

Diagnose why Stripe Checkout, the Billing Portal, or your webhooks aren't working: missing signature verification, raw-body mistakes, no idempotency, test/live key mix-ups, broken success and cancel URLs, and subscription lifecycle gaps. Works across Next.js, Express, FastAPI, and serverless, with severity, evidence, and copy-paste fixes for each finding.

♿ a11y Regression Test Generator

by JustHandled Labs

$15

Generate runnable accessibility regression tests, not just a findings report. Detects a11y issues, missing alt text, unlabeled controls, keyboard and focus gaps, in your routes, components, or HTML, then emits Playwright + axe-core spec files with targeted assertions and remediation tickets for each. Previews the tests first and writes them only on your confirmation.

Landing Page & Conversion Copy Gate

by PubsProToolkit

$16

An adversarial reviewer for landing pages and conversion copy. It flags an unclear value proposition, a weak or buried call to action, missing social proof, funnel friction, and unsupported claims, then returns a PUBLISH / REVISE / HOLD verdict — before the page goes live.

📏 Handle Rules Linter

by JustHandled Labs

$9

Check a desired handle against every platform's username rules and find the form that works everywhere. Flags handles that break a platform's length limits, use a disallowed character (like a period on YouTube or TikTok), or start with a disallowed character, and recommends the safe consistent form (4 to 15 lowercase alphanumeric). Covers X, Instagram, TikTok, YouTube, Twitch, GitHub, and Bluesky. It checks the rules, not availability.

🧭 Doc Drift Detector

by JustHandled Labs

$13

Catch documentation that drifted from your code. Flags functions and methods named in your docs that are gone from the source, CLI flags documented but missing from the arg parser, env vars the docs mention but the code never reads, example imports of modules that no longer exist, and npm scripts or Make targets your docs reference but the project does not define. Cross-references your README and docs against Python and JS/TS source.

🧰 Tool Schema Linter

by JustHandled Labs

$12

Lint the function-calling tool definitions your agent exposes. Flags tools with no description, parameters missing a description or a type, overlapping or near-duplicate tools, too many tools for reliable selection, an unsafe tool exposed without a guard, required parameters missing from the schema, and free-form parameters that should be bounded with an enum. Cleaner tool schemas mean an agent that picks the right tool.
