Tinybench is a simple, lightweight JavaScript benchmarking library for running benchmark tasks and measuring latency and throughput with timing based on Web APIs (process.hrtime or performance.now). It provides statistically analyzed results such as percentiles and margin of error, and supports concurrency and event-style notifications (EventTarget-compatible).
Project status
- Actively maintained, with an upstream GitHub push as recent as 2026-10-02 and multiple tagged updates in early September 2026.
- Update cadence appears fairly steady, with updates on 2026-09-04, 2026-09-05, 2026-09-09, and then another upstream activity on 2026-10-02 (suggesting ongoing development rather than a long pause).

Recent updates
v6.2.0
tinybench v6.2.0 primarily documents a new option, `overriddenIterationCost`, intended to decouple the time budget from the sampling/iteration cost. The provided code diff excerpts focus on regenerated documentation output (version stamping and updated TypeDoc “Defined in” commit references), and do not show any runtime or API implementation changes.
Featuresv6.1.6
Release v6.1.6 is a small bug fix focused on TypeScript typing support for non-DOM runtimes. The release notes specifically call out improvements to the project’s type declarations to work outside browser environments.
v6.1.5
v6.1.5 is a small bug fix release focused on improving compatibility with Bun by guarding how Bun.version is accessed and preserving the existing version fallback behavior. The release notes only mention these two runtime detection fixes.
v6.1.4
v6.1.4 is presented as a small bug fix release. The release notes claim a change in the TypeScript types around preserving EventTarget listener fallbacks.
v6.1.3
v6.1.3 is described as a small bug fix release, focused on enforcing an optional hook signature. The provided diff, however, shows mostly generated documentation updates plus a type-level change introducing a new HookMode alias.
Featuresv6.1.2
v6.1.2 is a small maintenance release focused on type exports and numeric formatting behavior in table output and time conversion. The release notes mention exporting HookMode and TimestampProviderName, rendering rme via formatNumber, and making mToNsBigint accept fractional milliseconds.
v6.1.1
Release v6.1.1 performs a version bump and makes a small CI workflow change related to publishing documentation. The only code changes in this diff are in the GitHub release workflow and package.json version.
v6.1.0
v6.1.0 adds timer overhead correction to reduce measurement inflation from timestamp provider call cost, along with timer saturation detection that can dispatch warning events. It also exposes a per-task resolution diagnostic (Task.detectedResolution) and ships new public helpers for calibrating and classifying timer behavior.
BreakingFeaturesv6.0.3
v6.0.3 is described as a small bug fix release. The release notes mention a documentation export fix (mToNs for a README console.table example) and a CI workflow conditional tweak.
v6.0.2
Release v6.0.2 documents only linting-related changes, specifically updating the ESLint configuration and adding a JSDoc rule. The provided code diff, however, largely shows regeneration or re-bundling of the documentation website (many docs HTML files) rather than application or API logic changes.
