About TraceRN
TraceRN started as a fix for our own problem: every crash tool was either too heavy, too expensive, or treated React Native as an afterthought. So we built the one we wanted — small enough for indie apps, solid enough for production teams.
What we believe
A ~13 KB SDK with no native modules for core logging. Monitoring should never be the heaviest thing in your app.
Every public SDK method is internally try-caught. If TraceRN fails, it fails silently — your users never notice.
A free tier that hard-caps instead of surprise-billing. Paid tiers priced for indie teams, not enterprise procurement.
Built around Hermes, Metro, Expo, and offline-first mobile reality — not a web tool with a mobile wrapper.
The story
Shipping React Native apps and watching crashes vanish into the void — or into enterprise tools priced for someone else.
tracern-sdk published to npm: batched logging, offline queueing, and automatic JS error capture in one tiny package.
Live logs, crash grouping, release health with session heartbeat, source maps CLI, team orgs, and alerts — free tier included.
Native crash capture and deeper mobile insights — shaped by what early teams actually ask for.
TraceRN is built in the open — the SDK is published as tracern-sdk and the monorepo lives on GitHub.
Free plan: 10k logs/mo, hard-capped. Install the SDK, paste your key, watch events land — then upload source maps from CI when you go paid.
