See your requests move
Open the built-in dashboard, send a request and watch the target function wake. Follow asynchronous work through a queue, observe job executions, and inspect replicas as they start and stop.
The Guided Tour takes you through the core features with copyable cURL commands and an executable Bruno collection. Each step explains the expected result and what to look for in the UI.
Build with the features you need
| Your application needs to… | Start with |
|---|---|
| Call an HTTP service and wait for its response | Synchronous functions |
| Accept work now and process it later | Asynchronous functions and callbacks |
| Notify ready subscribers | Events |
| Execute a task once or on a schedule | Jobs |
| Store small state, counters or temporary artifacts | Data Sets and Data Files |
| Reduce idle replicas or scale out under load | Autoscaling |
| Connect a worker over WebSocket | Official clients |
| Wake consumers from Kafka lag | Kafka connector |
| Show a wake-up experience in a frontend | Planet Saver |
Understand and operate SlimFaas
SlimFaas is an HTTP proxy with orchestration workers and a replicated SlimData store. It can manage Kubernetes workloads, Docker containers or native local processes. The deployment model changes; application routes stay familiar.
Read How It Works, look up a route in the API Reference, configure the dashboard, or export telemetry with OpenTelemetry. For measured performance and reproducible commands, use Benchmarks.
Open source, built together
SlimFaas was originally created by AXA France. Contributions, reproducible bug reports and documentation improvements are welcome.
