It plans the stack, prices it at your scale, and hands back package names, environment variables and docs. Your assistant writes the code.
Then keep going in the same chat. Pick up a saved project, price a change before it is built, track setup step by step, and ask why the bill went up.

VS CodeI’m building a booking app for yoga studios with sign-in, payments and email reminders. What should it run on, and what will it cost at 20,000 users?
recommend_stack, the tool your assistant calls, at today’s prices.Stacks read from each product’s public code.
No vendor pays to be listed or ranked higher, and there are no referral links.
Every price change is public: who changed what, when and why.
One startup at a time: what it makes and the services it runs on, read from its public code and linked to their prices.
Point it at your files, repository or website to see what to keep and what to change. Then bring in what you actually pay, next to what you estimated.
Sign-in required for billing and saved stacks.
Import a CSV, upload a text-based PDF, paste an invoice or enter an amount. Recurring subscriptions add completed months automatically.
Supported OpenAI, Anthropic, Vercel, Stripe, AWS and DigitalOcean connections sync completed months nightly. Billing access depends on the provider; personal Claude API keys cannot read organization costs.
When receipt forwarding is enabled, send receipts to your private billing address and review the service, month and amount in Billing. It reads the email body, not attachments; upload PDFs separately.
Save a stack or audit and enable alerts for price changes, approaching cost jumps, expiring credits and bills above estimates. Checks run daily using saved usage assumptions and require a confirmed email.

Reads its manifests and config files.
Reads hosting from its response headers and the scripts it loads (payments, analytics, errors). It can't see databases or back-end services, so add files too if you can.
Your AI coding app can already see the codebase. Connect Kong Reviews, then ask:
Audit this app's stack with Kong Reviews: detect what it runs on, then audit it for 10,000 users growing to 50,000.It reads the project, calls detect_stack and audit_stack, and shows the report in the chat.
Your audit appears here: a grade, what to change first, and what each service costs as you grow.
What kinds of app are built with, and what they cost at three stages: MVP (about 100 users), Growth (about 10,000) and Scale (about 100,000). Every price comes from the cost engine with today's checked prices.
Stacks and audits you saved here or from your AI assistant. Turn on alerts to hear when prices, cost jumps or credits change one, or press Check to re-run it with today's prices.
What your services actually charged, next to what we estimated.
Every developer service we've looked at. Those priced in full have every plan, what each includes and the cost as you grow; the rest show the free tier and lowest paid price from their pricing page.
Credits and lock-in come from the cost engine, so only services priced in full have them.
Products startups have built, with the stack each one runs on, read from its public code. Filter by what it is and what it's built with, then see what a stack like it costs.
Add one address to Claude, ChatGPT, Cursor or VS Code. Your assistant can then plan the stack, price a change before it writes the code, keep setup on track and explain your bill, with the source and date behind every price.
Every change to a price, plan or limit is public. Trusted contributors' changes go live once their quote checks out; the rest are settled by votes and moderators. Read the moderation log, follow the change feed, or download the whole catalogue.

We may add paid plans later, for things like tracking real bills and team accounts. Nothing is for sale today.
It scopes what you build next, a new product or a feature for the app you already have: which services to use (hosting, database, sign-in, email, payments, analytics and more), how to set them up, and what they will cost now, as you grow and after startup credits. Use it on this website with a free account, or from your AI assistant over MCP each time you plan a feature.
From each vendor's own pricing page. 70 of the 70 vendors in the cost engine were checked against their pricing pages in October 2026; any others are marked unverified. The other services on Vendors were read in October 2026 for their free tier and lowest paid price; the ones we couldn't read are marked Not Priced Yet. Both keep growing: we add vendors and services as we research them. Every answer lists its sources and the date each price was checked, and a price counts as out of date after 14 days. Check the vendor's page before you commit to anything.
