Skeptical, then convinced
I went in skeptical — most tools in this space overpromise. It actually delivers on locale management and synchronization, and keeps translations in sync with code caught me off guard. Primarily aimed at JavaScript developers is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Use it every day
Honestly didn't expect to like it this much. Framework integrations (Next.js, React, Vue) is exactly what I needed, and keeps translations in sync with code. I do wish primarily aimed at JavaScript developers, but I reach for it almost every day now and it just clicks.
Solid for our team
We rolled this out across the team last quarter and aI-assisted translation across many languages. AI-powered translation generation fits neatly into how we already work, and typeScript support and autocompletion removed a step we used to do by hand. AI translations may need human review, which is the main caveat, but it has held up under daily use.
Years in this space
I've evaluated a lot of these over the years. What stands out here is framework integrations (Next.js, React, Vue) — handled better than most — and keeps translations in sync with code. Primarily aimed at JavaScript developers is my one real gripe. Worth the time if this is your use case.
