Heliox IDE

Design agents.
Run them anywhere.

The open-source dashboard for designing agentic flows on a visual canvas. Compile them from a sentence, verify them with a benchmark that actually executes, and export to a portable format that runs identically on TypeScript, Java, and Python. No framework lock-in. No cloud lock-in.

Design System
Security Role

Arrange your mind.
And your code.

Most AI coding tools are chat windows bolted onto editors. Heliox provides a Figma-inspired spatial workspace where every panel is a draggable, resizable window on an infinite desktop.

  • Infinite Pannable Desktop

    Pan and zoom with trackpad gestures. Snap alignment guides help you position windows perfectly.

  • Visual Connections

    Draw visual arrows between related windows. Drag roles and constraint modifiers onto sessions like a design tool.

  • Multi-Project Kanban

    Keep your backlog visible on the canvas alongside your code, parsed directly from local markdown files.

Mods system

Attach behavioral modifiers to sessions to control quality gates, safety constraints, and execution boundaries.

Portable across
every runtime.

Every flow exports to a single, vendor-neutral .flow.json — no proprietary format, no hidden state. Drop it into the TypeScript, Java, or Python SDK and it runs identically: Heliox is conformance-verified across TypeScript, Java, and Python for DAG order, text output, typed-output rule, tool-calling, and contract/model round-trip; loop parity proven in TS + Java.

  • One portable artifact

    The full DAG — steps, roles, mods, contracts — compiles to one JSON file. No framework-specific glue code required to run it elsewhere.

  • Three conformant runtimes

    The TypeScript, Java, and Python SDKs are conformance-tested against the same matrix — not just API-compatible, provably identical.

  • Two ways to integrate

    Serve it over HTTP with heliox serve (/run, /flow, /health, Bearer auth), or expose it as an MCP server so N8N and other tools can call it directly.

Verification by execution.

Not lint rules. Not vibes. Every run is proven by actually executing it — and every model earns its place on the leaderboard before you trust it with one.

The Performance Frontier runs the artifact.

No linting. No opinions. Every candidate boots a real Express server, runs real vitest suites, and gets scanned with axe-core — scored with statistical confidence intervals by a self-calibrating judge, not a single noisy sample.

No Vendor Lock-in.

Bring your own key. Save encrypted connection profiles to any OpenAI- or Anthropic-compatible endpoint — local or hosted. Your code, your infra, your keys.

Benchmarked, not guessed.

The Arena runs models head-to-head on real tasks and ranks them on a leaderboard. A model only earns the “Benchmarked” seal once it has proven itself there — and that seal feeds smart model routing, so Heliox recommends the right model per step with data, not opinion.
