AI orchestration

Build AI agents you can actually follow

Connect any model. Inspect every decision. Keep humans in the loop. Every prompt, response, token count, and timing is captured in the execution trace.

Any provider, one canvas

OpenAI, Anthropic, and Google Gemini — all routed through OpenRouter. Swap models without rebuilding workflows.

Structured outputs

Force JSON responses, tune temperature, and reference any node's output with {{nodeId.output}} templating.

Inspect every execution

See the exact prompt, the raw response, and what happened next — per node, in real time.

Code when you need it

Other tools make you choose between a visual builder or code. With FluX you get both — a JavaScript Code node drops in anywhere, with inputs and outputs visible right next to the settings.

// transform the payload
return items.map(x => {
...x,
flagged: x.score > 0.8,
});

Move fast. Break nothing.

Short feedback loops that keep you in the flow — from first draft to production traffic.

Test with real data

Run a single node or the whole workflow with live payloads.

Durable waits

Pause for minutes or months — state persists, then resumes exactly where it left off.

Live execution map

Watch each node fire in real time, with inputs, outputs, and errors per step.

Fail loud, recover fast

Error-handler branches and retry logic, not silent dead ends.

Enterprise-ready

Reliable. Scalable. Secure.

Security and governance baked into the engine — so you can automate in production without losing control.

Auth gates

Require valid API keys or credentials before a workflow proceeds.

Idempotency guards

Prevent duplicate processing when webhooks fire twice.

SSRF protection

Private network targets are blocked unless you explicitly opt in.

Database policy

Raw queries are scoped and internal tables are off-limits.

Human approval

Pause for sign-off before sensitive actions run.

Distributed mode

Scale across workers over Kafka, or run everything in-process.

Simple enough to see.
Powerful enough to ship.

Join the teams building automation they can actually explain.
