Researches the exact, current cost to build and run a website or app — hosting (Vercel, Netlify, Cloudflare), database (Neon, Supabase), domain, email, payments fees (Stripe, Mercado Pago, Pix), auth, storage — compares free and paid options and recommends the best value. Use when the user asks "quanto custa", "qual o valor", "qual é mais barato", "custo-benefício", "precisa pagar?", or before choosing where to host a project.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

Cost estimator
Prices change. Never answer from memory — fetch each provider's official pricing page today and cite it. If a page can't be fetched, say so and mark that number as "não confirmado".
1. Understand the project (ask only what you can't infer)
- Type: landing page, site with booking/agenda, online store, game, app with login.
- Commercial or personal? (Matters: e.g. Vercel Hobby is non-commercial only — a client's business site needs Pro or another host that allows commercial use on free tier.)
- Expected traffic (visits/month), storage (images/videos), need for login, database, payments, email, custom domain.
2. Price every layer (official pages)
| Layer | Check at least |
| Hosting | Vercel, Netlify, Cloudflare Pages/Workers |
| Database | Neon, Supabase (free tier limits: storage, compute hours, pausing) |
| Domain (.com.br / .com) | Registro.br, Cloudflare Registrar, Porkbun — first year and renewal |
| Email transactional | Resend, Brevo |
| Payments | Stripe, Mercado Pago, Pix — % fee + fixed fee per transaction, payout time |
| Auth / storage / other | Only if the project needs it |
For each: free tier limits, first paid tier, what triggers the jump, overage cost.
3. Calculate
- Convert USD → BRL with today's rate (fetch it; state the rate and date). Mention IOF on international card charges (check the current percentage).
- Show setup cost, monthly cost and yearly cost for: (a) cheapest viable, (b) recommended, (c) growth scenario.
- Payments: show the fee on an example ticket (e.g. R$ 80 haircut → fee R$ X → she receives R$ Y).
4. Answer format (Portuguese)
- One-line answer: "Dá para começar com R$ X/mês" (or "de graça, com estes limites…").
- Table per scenario with sources (link per row).
- Recommendation and why, including the gotchas (commercial-use rules, sleeping free databases, renewal price higher than first year).
- Date of the research.
Optional: if the user uses Notion, add the table as a page/database there (Notion MCP).
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
