Who this is for
We built Cafiyn Pulse for the people shipping real products without a big team. If one of these is you, it is for you.
Solo founders
You are the CEO, the engineer, the ops team, and marketing at once. A $50k audit is out of reach, and skipping one is not really an option either.
Vibe coders
You shipped in a weekend with Lovable, Bolt, Replit, or v0. Now it has to hold up in front of real users.
Small engineering teams
Two to ten people shipping to real users, with no dedicated security or SRE hire yet. You want a checklist, not a lecture.
AI builders
You are shipping an AI product and every provider price feels arbitrary. See the real bill before it arrives.
Freelancers and agencies
You hand off client work every week. Your reputation rides on the checklist you run before the invoice goes out.
Mobile app makers
React Native, Flutter, Expo. A store rejection costs you a week. Catch the reasons before you upload.
What Cafiyn Pulse actually does
Three tools, one login, ten seconds to sign up, and free forever. Here is what each one does.
Stack Grader
A security and reliability audit across ten categories, with tiered scenarios and a prioritized fix plan.
OpenCost Comparator
Live pricing math across more than forty AI models, on your own usage numbers.
OpenLaunch Checklist
A go-live checklist that adapts to your stack. Every item says why it matters, what to do, and how to check.
OpenStack Grader: the categories that matter
The ten categories where small teams most often lose points once real users arrive.
Cost Comparator: the model roster
More than forty models across five categories, checked against public pricing every week.
Launch Checklist: the stacks we support
Pick your stack and the checklist tailors itself to it.
Why not a scanner or a spreadsheet
Why we chose guided self-assessments and live calculators over noisy scanners and stale spreadsheets.
Frequently asked questions
The questions builders ask us most, answered straight.
?Is Cafiyn Pulse really free?
Yes, and for good. It is free forever: no credit card, no trial clock, no upsell. We built it so builders can reach production quality without paying for a consultant.
?Which AI providers does the Cost Comparator support?
The Cost Comparator supports 40+ models across five categories: text (Claude, GPT, Gemini, DeepSeek, Grok, Mistral, Llama, Cohere, Perplexity), text-to-speech (ElevenLabs, OpenAI, Google, Deepgram, Azure), speech-to-text (Whisper, Deepgram, AssemblyAI, Google, Azure), image (DALL-E, Stable Diffusion, Flux, Ideogram, Recraft), and video (Runway, Pika, Luma, Kling, Sora).
?What stacks does the Launch Checklist support?
Lovable, Bolt.new, Replit Agent, v0 (Vercel), Next.js custom, React Native and Expo, Flutter, WordPress, Shopify, Webflow, or a custom stack. Each item explains why it matters, what to do, and how to verify.
?Do you sell my data?
Never. We do not sell, rent, or share your data, and you can export or permanently delete everything from your profile whenever you want.
?How is the Stack Grader different from a security scanner?
A scanner reads code or URLs and hands you noise. The Stack Grader asks ten plain-English questions about the things that actually take small teams down, then gives you a tiered, personalized fix plan.
?Who is Cafiyn Pulse for?
Solo founders, vibe coders using Lovable, Bolt, Replit, or v0, small engineering teams pre-Series-A, AI builders, freelancers and agencies, and mobile app makers preparing for App Store or Play Store submission.
?Does Cafiyn Pulse work with mobile apps?
Yes. Both React Native with Expo and Flutter are supported stacks in the Launch Checklist, with mobile-specific items like crash reporting and app-store asset preparation.
?Do I need an account to use Cafiyn Pulse?
You can try the tools without signing up. An account lets you save your progress, revisit a checklist or grade later, and export or delete your data, but nothing is gated behind a paywall. There is no credit card and no trial clock at any point.
?How is Cafiyn Pulse related to the Cafiyn products?
Pulse is a free suite of builder tools: the Cost Comparator, Launch Checklist, and Stack Grader. It is separate from the paid Go-To-Market Engine, Cafiyn Lens and Cafiyn FlyWheel. Pulse helps you ship a product to production quality; the engine helps you find demand and win the market once it is live. You can use either without the other.
?How often are the tools and model data updated?
Regularly. The Cost Comparator tracks 40+ models and is updated as providers change pricing or release new models, and the Launch Checklist and Stack Grader are revised as best practices and platform requirements move. Because the tools are free and web-based, you always get the current version with no upgrade step.
Free forever. Ready in ten seconds.
No credit card, email verification only, and you can export or delete everything whenever you want.
