Tutorials
Hands-on walkthroughs to deepen your understanding of the framework and get up and running quickly.
Tutorials
Start with Getting Started and work through each tutorial in order. The path is intentionally small: learn the flow model, then see how it stretches into service boundaries and live model-backed workloads.
ObzenFlow is a durable execution runtime in Rust, built on event sourcing with deterministic replay. Start with one concrete example, then continue into tutorials and pillars when you are ready.
Use the piggy bank example to see how ObzenFlow fits into a real write-side service: HTTP commands in, journal-backed facts through the flow, and a projection out the other side.
Use the Hacker News digest example to see how ObzenFlow wraps live HTTP data and model inference in deterministic flow structure, durable journals, and replayable evidence.
What these tutorials cover
Each walkthrough focuses on a real-world pattern.
Journal-backed bank transactions with joins and read models
Live AI inference with accumulation and replay
How flows compose into real services with durable evidence
Replayable journals and auditable execution traces
After the tutorials
Once the examples feel natural, read the philosophy with a much more concrete mental model in hand.
