Duration Labs provides developer tools, APIs, and infrastructure for building time-aware applications — from scheduling to analytics to real-time coordination.
Features
A complete toolkit for developers who need precision, reliability, and simplicity when working with temporal data.
Durations, intervals, windows, and ranges as first-class types. Compose, compare, and transform time values without boilerplate.
Resolve conflicts, find free windows, and handle recurring events across timezones with a single API call.
Ingest, aggregate, and query temporal data streams with sub-second latency. Built for dashboards and monitoring.
Every operation is timezone-aware by default. No more `Z` vs local confusion. IANA database backed.
Full TypeScript support with exhaustive types. Catch temporal bugs at compile time, not in production.
Coordinate distributed events with causal ordering, vector clocks, and wall-clock reconciliation.
How It Works
Three steps to add time-aware capabilities to any application.
Add our lightweight SDK to your project. Zero dependencies, tree-shakeable, runs everywhere — Node, Deno, edge, browser.
Declare schedules, windows, and constraints using our declarative API. Type-safe, timezone-aware, conflict-free.
Deploy with built-in observability, automatic DST handling, and high-availability SLA. Focus on your product, not edge cases.
Free tier includes 10K API calls/month. No credit card required. Deploy your first temporal app in under 5 minutes.
