What does deterministic scoring mean?

No randomness. Your constraints go through a 6-layer pipeline evaluating 180+ technologies against Performance, DX, Ecosystem, Maintainability, Cost, and Compliance. Same input, same output.

Deterministic scoring engine

Scored tech decisions.
Not opinions.

Q: How is this different from asking ChatGPT?

ChatGPT gives different answers every time you ask. StacksFinder produces identical scores for identical inputs. Every risk flag is sourced from documented production incidents.

Q: Is there a free plan?

Yes. The free tier includes 3 reports per month, markdown export, and 30-day history. No credit card required.

Q: What technologies are covered?

180+ technologies across frontend, backend, databases, hosting, auth, payments, ORMs. Each scored manually against 6 criteria with sourced data.

Q: What is the MCP Server?

A Model Context Protocol server that gives AI coding assistants direct access to deterministic tech scoring. The only MCP server for tech recommendation.

Every project starts with "what stack should we use?" and every answer is someone's opinion. StacksFinder replaces opinions with scored, sourced, reproducible data for 180+ technologies.

You asked "what framework should I use?"

Here's what you got back.

The opinion

What frontend framework should I use for a SaaS dashboard?

AI Assistant I'd recommend React with Next.js! It's the most popular framework with a huge ecosystem. Many companies use it successfully...

But what about Vue or Svelte?

AI Assistant Actually, Vue is also a great choice! It's easier to learn and has excellent documentation. You could also consider Svelte...

Why trust a score?

Deterministic

No randomness. No model temperature. Same project constraints produce the same scores. Today, tomorrow, next year. You can audit every output.

Sourced

Versioned

Every scoring dataset is versioned. When scores change, you know what changed and why. Full transparency — no black box.

"We went from spending a full day on proposals to sending three before lunch. The deterministic scoring gives our clients confidence we're not just picking favorites."
