Cafiyn Pulse
Free for everyone building

Whoever you are, whatever you are building, the boring parts are the same.

Cafiyn Pulse is free tools for anyone shipping software into the world: vibe coders on Lovable / Bolt / v0 / Replit, solo founders who are also the ops team, indie hackers bootstrapping revenue, stealth teams with three people and an NDA, side-project builders squeezing hours between meetings and dinner. The launch, the AI bill, and the production readiness look identical from all five vantage points. So do the tools.

Common questions

FAQ.

Who is Cafiyn Pulse for?

Anyone building anything. Specifically: vibe coders shipping with Lovable / Bolt.new / v0 / Replit, solo founders who are the whole company, indie hackers building bootstrapped revenue, stealth teams launching to a small circle first, and side-project builders shipping on nights and weekends. If you are moving code or content into the world and have a launch date coming, the tools apply to you.

Do I need to pick a persona?

No. The tools are the same for everyone. The persona pages exist so you can see how the tools apply to your specific working style, and read guidance written for how you actually build (part-time, in stealth, at a solo bench, or on Lovable) rather than for a mythical startup with a team of ten.

What if I do not fit any of the personas cleanly?

Most people fit two or three. A stealth founder shipping on nights and weekends who uses Lovable is all four of vibe coders, stealth builders, side projects, and solo founders. Pick whichever page reads closest to your day-to-day. All roads lead to the same three tools.

Are the tools different per persona?

No. The Stack Grader, Cost Comparator, and Launch Checklist are the same product regardless of who you are. The persona pages are a lens on the same tools with different examples, different fears, and different phrasing.
