Boosthis measures TTI, FID, and TTFF on every screen and route, rates them against shared budgets, and helps you find and fix what's slow — all without leaving your machine.
Runtimes
Boosthis ships a first-class performance pack for each runtime — same scoring model, same strict PII guard, same AI tool surface across all six.
Drop useBoosthis("ScreenName") into any screen for
instant, on-device performance ratings — every screen measured,
regressions caught early, and nothing ever leaves the device.
A built-in dashboard tab shows the full meter page, and your AI
assistant can read it too.
Add @track_perf("route") to any function.
One extra line — boosthis.mount(app) — mounts a live
dashboard at /_boosthis/ on your existing Flask or
FastAPI port. Run boosthis serve without a web app for
the same dashboard at localhost:7787.
Catches the runtime-specific problems that actually slow Python
services down — with a concrete fix for each, all local.
Add the boosthis() Express middleware and optionally
mount(app) for the live /_boosthis/
dashboard. Catches the runtime-specific problems that actually slow
Node services down — with a concrete fix for each, all local,
no cloud dependency.
Call startWebVitals() once at page load for real
browser Web Vitals per page, rated against the same shared budgets.
Catches the browser-specific problems that hurt real-user
experience — with a concrete fix for each, all in the browser,
nothing leaves the page by default.
Wrap any com.sun.net.httpserver handler with
BoosthisHandler, or any framework route with the generic
Wrap helper, for per-route ratings against the same
shared budgets. Catches the runtime-specific problems that actually
slow JVM services down — with a concrete fix for each, zero
dependencies, JDK stdlib only.
Wrap any http.Handler with
boosthis.Middleware for per-route ratings against the
same shared budgets. Catches the runtime-specific problems that
actually slow Go services down — with a concrete fix for each, zero
dependencies, pure stdlib.
Scoring model
Every runtime is rated against the same shared budgets and distilled into a single 0–100 score, so you can compare performance across RN screens, Python routes, and Node.js handlers side-by-side — no per-tool guesswork.
Ratings are fully local — timings and labels never leave your machine unless you explicitly join the invite-only telemetry program.
How it works
Detection runs entirely on-device; clear fix guidance is delivered inside your dashboard and AI tools exactly when an issue is detected.
React Native: useBoosthis("ScreenName").
Python: @track_perf("route").
Node.js: app.use(boosthis()).
No account required for local measurement.
Boosthis computes TTFF, TTI, and FID on every interaction, rates them against shared budgets, and detects known performance issues entirely on-device — nothing leaves the process.
Connect your AI assistant to give it read-only access to the full live meter page, per-screen diagnosis, session summary, and fix suggestions.
We help you find and fix your project's performance issues — clear guidance, delivered right in your dashboard and AI tools. Nothing sensitive ever leaves your system: your source code, timings, and screen names stay on your machine.
Pricing
Billed monthly in Saudi Riyal (SAR), and the price you see is the final amount charged — inclusive of any applicable taxes, with no hidden fees. Major cards are accepted, and if you pay from abroad your bank converts automatically. Boosthis is invite-only: a plan activates inside your dashboard once you have an invitation.
Your first project, fully instrumented.
Full toolkit: tracing, full telemetry, unlimited AI connections.
Room for a small team shipping several projects.
No project cap — run everything on Boosthis, with priority support.
Plans renew automatically each month until cancelled. Cancel anytime — you keep your plan until the end of the paid month, and a lapsed plan never deletes your data. Fees are prepaid for the month and non-refundable except where the law requires — full details in the Refund & Cancellation Policy.
Privacy
Boosthis was designed so that nothing sensitive can leave your app, even if you misconfigure it.
