What’s the single stack decision that doubled your shipping speed this year?

Hey Product Hunt! 👋

Shipping in public has completely evolved. Ideas that used to take months to build and deploy can now be built and shipped in days.

While building several full-stack AI web apps recently, I noticed a massive shift in developer velocity when moving from heavy server infrastructure to client-side WASM & edge computing.

Here are 3 stack decisions that cut our dev cycles by 80%:

1️⃣ In-Browser WASM Databases (sql.js): Storing vector embeddings in WASM SQLite eliminated external DB subscriptions, setup time, and gave sub-5ms queries.
2️⃣ Lightweight Edge APIs: Using serverless endpoints + fast LLM inference APIs (Nemotron / Gemini) instead of complex microservice boilerplate.
3️⃣ Automated CLI Verification: Running local standalone test runners to stress-test edge cases before every production push.

I’d love to hear from fellow makers & engineers:
• What is the single tool, framework, or workflow hack that accelerated your shipping speed recently?
• Are you leaning towards client-heavy WASM architectures or cloud serverless?
