AI tech stack generator
A stack designed around your budget, scale and compliance.
Describe what you’re building and what you’re working with. StackPrism picks each part with a reason, draws the architecture, checks every technology against today’s data and writes the brief your coding agent builds from.
How it works
Three short steps on your side, then the diagram, its health check and the hand-off. Most stacks take about a minute to design.
Describe the idea
A sentence or two about what it does and who uses it. You don’t need technical terms: “card payments” is enough, unless you already know you want Stripe.Set your constraints
Optional chips for budget, expected scale, time to launch, where your users are, compliance, what you know, what you already use and how you feel about lock-in. Each pick later says which of these it’s based on.Answer a few questions
Only where there’s a real choice, such as which sign-in provider or how buyers and sellers message each other. Anything your idea or constraints already settle isn’t asked again, and you can skip them all to take the defaults.Get a diagram with a reason for every pick
Components grouped by where they run, how they connect, and why each one is there. Select any part to see what it does, or what stops working if it goes down.See its health today
Stack Pulse checks every technology against live data: support dates from endoflife.date, licence changes, unmaintained projects and vendor status pages. Once there’s code, each pinned dependency is checked against OSV.dev and CISA’s list of vulnerabilities attackers are using.Hand it to your coding agent
Copy a build brief written for Claude Code (STACK_BRIEF.md), Codex (AGENTS.md) or Cursor, or connect your agent through the MCP server so it fetches the brief and checks packages itself.
What you can tell it
The constraints step, as you’ll see it. Pick any that apply, leave the rest, and add your own must-haves such as “No AWS”.

What you need
Designing a stack uses AI, so it needs a free account. Everything else on this page, including the examples, is open.
No account
Designing a new stack needs a free account
- Open any example stack in the editor, with its live health
- See what breaks if a part goes down
Free account
Sign in with Google, no card
- A monthly AI allowance: roughly 25 stack designs or 100 Prism Agent messages
- Save your stacks and come back to them
- Ask Prism Agent for changes: you see the diff before anything moves

Questions
Is the tech stack generator free?
Yes. A free account comes with a monthly AI allowance of roughly 25 stack designs, and Pro gives you 10 times that. Example stacks open in the editor without using any of it.
What does it ask me?
Your idea first. Then an optional constraints step (budget, scale, time to launch, where your users are, compliance, skills, providers you already use, lock-in), then a few questions about choices that are still open.
Every answer is optional. Skip them and you get sensible defaults for the kind of app you described.
How is this different from asking ChatGPT or Claude for a stack?
A chat model answers from training data that stops at its knowledge cutoff, so it can suggest a framework version that’s out of support or a service that changed its licence. StackPrism checks each pick against today’s data, draws where every part runs and how it connects, and keeps the result as a project you can change and hand off.
Your coding agent then builds from that plan instead of picking its own stack as it goes.
Will it tell me what the stack costs?
No. StackPrism has no pricing data, so it doesn’t quote prices. Your budget answer still shapes the picks, for example starting on free tiers or choosing managed services over ones you’d run yourself.
Can I change the stack afterwards?
Yes. Ask Prism Agent for a change, such as “replace Auth0 with Clerk” or “add a cache in front of the database”. It plans the change and shows you the diff before anything moves, and you can undo it. Prism Agent needs a free account.
How do I give the stack to Claude Code, Cursor or Codex?
Use Hand off in the editor. It writes a build brief with the stack in build order, how the parts connect, install commands, environment variables, a production checklist and any live findings, plus the exact steps for your agent. Or connect the agent once through the MCP server and it can fetch the brief itself.
I already have code. Can it work from my repo?
Yes: map your GitHub repo instead and you get the diagram of the stack it really runs on. To check its dependencies without signing up, use the dependency check.
