When to choose Logixlysia
- You want Pino performance with Elysia-native
store.loggerergonomics. - You need file logging and rotation without wiring a separate drain.
- You prefer incremental context (
mergeContext) plus automatic access logs instead of migrating to a wide-event-only API.
When to consider evlog
- You need a logger that spans more than Elysia: evlog also covers Nuxt, Nitro, Next.js, and Hono.
- You want evlog’s CLI and observability scoring built in.
- You want evlog’s error catalog and client/browser logging.
- You rely heavily on
evlog/aiandevlogauth integrations out of the box.
Benchmarks
Run the monorepo benchmark package:
bun run benchThe benchmark package has three request-path suites: an overhead floor (all sinks disabled — measures plugin dispatch cost only), a structured sink run (no-op transport/drain — measures log assembly and dispatch), and a file sink run. Compare like with like: the floor numbers contain no logging work by design. Results vary by machine — use them for regression tracking, not absolute rankings.
