I didn't believe the TypeScript 7 speed claims. So I benchmarked it on my own production app — not a toy repo.
1,358 source files. 260K+ lines. The live codebase behind lokerdollar.com.
One change: tsc → tsgo (TS7, rewritten in Go). Same tsconfig, same tree, --noEmit.
Cold type-check: 77.1s → 11.6s. 6.6× faster. −85% wall-clock.
Then the part most "10× faster" posts skip — I checked whether it still catches bugs. Seeded 4 classic type errors. Byte-identical diagnostics: same codes, same line and column. The speed isn't bought by missing errors.
But I'm not putting it in your CI yet — and here's the honest reason:
— It's a release candidate
— The native binary drops the JS typescript API, so typescript-eslint type-aware rules, ts-morph, ts-node and ts-jest break
— Custom transformers and incremental builds are still maturing
My call: run it now as a fast local / pre-PR check, and keep tsc as the authoritative CI gate until 7.0 ships stable. You get a 6.6× tighter local loop with zero risk to the pipeline.
The ~$190/year in saved runner minutes is rounding error. The real return is nobody waiting on a turtle.

React Bits & Lovable. Just try this cool stuff! 👍
#prototyping #uiux #nocode
Love this stack Alona! React Bits + Lovable is such a powerful combo for rapid prototyping. No-code/low-code but still keeping that custom UIX feel - that's the sweet spot! Have to try this cool stuff indeed. Great share! 👍
Health check fails at 2am. Left wakes a human and holds the rollback until someone acks. Right rolls back on its own in 41 seconds and you read about it at 9.
Same pipeline, same failure, drawn in the style of my CapCut World LA film.
Which one would you let touch production, and what would you need to see in the logs before trusting it?
