Deterministic synthetic traffic

Model the data.
Control the traffic.

Generate realistic, related, stateful event streams in readable YAML — then send them to Kafka, PostgreSQL, HTTP, files, or cloud. Runs on your machine, not as a hosted platform.

Get started How it works

Send generated events to

Local Synthstudio

Edit on your machine.
Same engine as the CLI.

Synthstudio is a local editor with Monaco, ST diagnostics, sample timeline, and run — not a hosted workspace. Your scenarios stay on disk.

  • No hidden scripting
  • Unknown fields rejected
  • Same seed, same data
  • Runs locally only
