Five IDEs.
One platform.
Every joule.
A desktop IDE with built-in AI that works offline. When you need more, the cloud is there, and you only pay the energy cost. Physics, not tokens or seats.
IDEs don't know what anything costs.
You can see lines of code, test coverage, and deployment status. But the one thing that matters most, how much energy your software burns, is invisible.
The right IDE for every workflow.
Five specialized environments. One shared platform. All energy-metered.
Lux
Replaces the entire HTML/CSS/JS/TS ecosystem with a single language. Ships native + WASM at 398 KB. Every component, every render, every route. All measured in picojoules.
Joule
Systems language with formal verification built in. Kani proofs, energy budgets per function, and WebGPU compute. All native. The language for firmware, kernels, and real-time systems.
Arc
Every programming language. Python, Rust, Go, C++, Java, TypeScript, COBOL, Fortran, Ada. All with energy metering and the Lift engine to migrate code when you're ready.
Data
Notebooks with energy receipts per cell. Python, R, Julia, SQL, and GraphQL with ML pipeline metering. Know the joule cost of every model train, every query, every visualization.
DevOps
Terraform, Kubernetes, Docker, Ansible, CI/CD. All stored as a queryable infrastructure graph. Pipeline energy metering, drift detection, container analysis, and compliance reporting.
One engine. Five projections.
Every JoulesPerBit IDE shares the same core: a purpose-built database for storage, a refined AI model, and picojoule energy metering. Learn one, know them all.
Purpose-Built Storage
A database engine designed for developer tooling. SQL, graph queries, full-text search, and vector similarity. Unified in a single embedded store with crash recovery, WAL protection, and energy metering built in.
Local-First Intelligence
An embedded AI model ships with every install and handles most tasks locally. No cloud, no cost. When your work needs frontier-class AI, the cloud is there. You only pay for what leaves your machine.
Picojoule Precision
Real energy measurements for every function call, every database query, every network request. Measured and receipted.
Migrate Any Language
Built into every IDE variant. Converts Python, Java, COBOL, C++, or any supported language to Lux (web) or Joule (systems), with formal verification of the translation and a side-by-side energy comparison.
The only IDE family priced in joules.
Every other IDE charges in seats or tokens. We charge in energy. Use less energy, pay less. It's physics, not pricing strategy.
Built for Compliance
Real energy measurements feed directly into compliance frameworks. No estimates, no consultants, no manual audits.
From on-ramp to native.
Start in the language you know. See its energy cost. Lift when you're ready. The path is always incremental.
Sign up and add a $5 balance. Takes 30 seconds.
Install the desktop app for your platform. macOS, Linux, Windows.
Open any project. The AI works locally for free. Cloud kicks in only when needed.
Pay for what you use. Nothing else.
No seats. No tiers. No per-user fees. The app ships with a built-in AI model that handles most tasks locally at no cost. You only pay when your work needs the cloud.
Code intelligence, completions, search, and analysis run on your machine. No internet required.
Frontier AI, cloud builds, collaboration, deployment. Pay the energy cost. Typical users spend $1–$10/month.
