Pulse is free.
Period.
Not a free plan. Not a trial. The product.
You pay the day one machine isn't enough.
Build with Pulse.
Scale with StreamFlow.
Two verbs. Two products. One progression.
Laptop
Canvas, CLI, SDK — the whole engine, embedded.
Production
One node, real traffic, your data. Ship it.
High availability
Multi-node, quorum durable, automatic failover.
Distributed mesh
Partitioned across nodes & regions, operated centrally.
Same runtime. Same application. You never rewrite — you only scale.
The transition is architectural, not functional. You start on one machine. You move to a managed, distributed control plane only when your operational needs require it.
No feature you build ever gets locked. The line isn't your tenth pipeline or your fifth user — it's the moment your architecture changes.
What changes when one node becomes many.
Enterprise
The dashed line is the frontier — everything above it is free forever; everything below needs StreamFlow Enterprise.
Free means self-hosted. You run Pulse on your own machine — $0, your data, your infra.
Rather we operate it for you? That's managed hosting — a separate, usage-metered option. Talk to us →
Read it, and trust it won't be taken away.
Read, fork, extend, embed in your own products — no strings.
Source-available today; each release auto-converts to Apache 2.0 on its change date. Terms only ever relax — never the reverse.
Build everything. Keep everything. Pay only when the architecture changes.
See it work in 3 minutes — no install, no signup. Then self-host when you're ready.
