Each one stands alone. Each shows its own progress.
Built for the people actually shipping.
Cafiyn Pulse is a free suite of pre-launch tools for anyone taking a real app from prototype to production, without the enterprise-security team, the DevOps consultant, or the finance department.
Vibe coders
You shipped in a weekend with Lovable, Bolt, Replit, or v0. It works. Now you need it to keep working when real users find it.
- Lovable app
- v0 to production
- Replit deploy
- Bolt.new launch
Small engineering teams
Two-to-ten-person teams shipping to real users, with no dedicated security or SRE hire yet. You want a checklist, not a lecture.
- seed-stage startup
- engineering leadership
- production readiness
- pre-Series-A
AI builders
You are shipping an AI product and every provider price feels arbitrary. Model the real bill before it lands.
- AI cost calculator
- LLM pricing
- token cost estimator
- Claude vs GPT
Freelancers and agencies
You hand off client sites weekly. Your reputation is on the checklist you follow before the invoice.
- client handoff
- agency workflow
- launch checklist template
- go-live process
Mobile app makers
React Native, Flutter, Expo. App-store rejections cost you a week. Catch them before you upload.
- App Store submission
- Play Store checklist
- Expo production build
- crash reporting
Why this matters
Most apps fail on the boring stuff.
Missing rate limits melt your OpenAI bill in a weekend. Unverified webhooks let strangers mark themselves as paid customers. Un-tested backups turn a bad migration into a business-ending event. Cafiyn Pulse is the pre-launch security audit, AI cost calculator, and go-live checklist you would hire a consultant to build for you: free, opinionated, and grounded in what actually breaks in production for solo founders and small teams.
Whether you are a technical founder validating your first SaaS, a vibe coder shipping a weekend project to real users, an agency handing off client work, or an engineering lead preparing for a Series-A due-diligence review, the three modules give you the exact next step for every gap they find.
