-
Screen recorder that writes bug reports
Vague bug reports burn developer hours; a recorder for non-technical teammates that captures clicks, console, and network, then writes the repro steps.

Analytics for documentation sites
Docs teams fly blind on what readers can't find; lightweight analytics surfaces failed searches, dead-end pages, and the articles you should write next.

Dead code cleanup for AI-built codebases
AI coding sessions leave orphan files and duplicate components everywhere; this maps the dead weight in a repo and opens deletion PRs.

Image size diffs on every pull request
Docker images balloon a layer at a time; a CI comment shows the size diff on every PR and names the layer that caused it.

CI that keeps docs code samples working
Docs code samples rot until users hit errors; this extracts every snippet, runs it in CI, and fails the build when examples break.

Stale feature flag cleanup bot
Stale feature flags rot into dead branches nobody dares touch; this finds flags at 100% rollout and opens the cleanup PR for you.

CI cost overlay inside the GitHub UI
CI minutes burn money invisibly; this overlays dollar costs and cache-miss warnings on every workflow run right in the GitHub UI.

Missing translation catcher for locale files
Shipping with missing translation keys embarrasses you in every locale; CI catches drift between locale files and drafts the gaps.

Hosted license keys for indie software sellers
Selling a desktop app or plugin means building license keys from scratch; a hosted API issues, validates and revokes keys with Stripe sync.

Token cost breakdown per feature and customer
Your OpenAI bill is one opaque number; a drop-in proxy tags every call so you see token spend per feature, per customer, per deploy.

Uptime and schema drift monitor for MCP servers
MCP servers fail silently and agents just get dumber; uptime checks plus tool-schema drift alerts for the servers your team depends on.

Turn real API traffic into MSW mocks
Writing API mocks by hand is tedious guesswork; record real traffic in DevTools and export ready-to-use MSW handlers and fixtures.

Breaking change alerts for third-party APIs
Third-party APIs break your integration without warning; this watches their OpenAPI specs and alerts you before deprecated fields hit prod.

Dangerous migration linter as a GitHub app
A single ALTER TABLE can lock production for minutes; this GitHub app flags dangerous Postgres migrations in the PR before they merge.

Before and after screenshots on every PR
Reviewers can't see UI changes in a diff; this shoots before/after screenshots of changed pages on every PR via your preview deploys.

Anonymized production clones for staging
Staging needs prod-shaped data but not real PII; nightly clones your Postgres with names, emails and cards scrubbed but relations intact.

Local setup checker for onboarding developers
New hires lose day one to broken local setups; a checker CLI verifies versions, env vars and services against your repo's manifest.

PII redaction proxy for LLM API calls
Teams in healthcare and legal can't send raw client text to LLM APIs; a drop-in proxy strips PII before the call and restores it in the response.

Tax ID validation API for SaaS billing
SaaS billing teams hand-check EU VAT and UK company numbers at signup; one API validates tax IDs, applies reverse-charge logic, and logs proof.

Changelog writer that reads your merged PRs
Connect a repo, get a user-facing changelog drafted from merged pull requests every week. Devs hate writing changelogs; users notice when they stop.
