Open-source, resource-efficient coding agent harness built for multi-session workflows, deep customizability, and high performance.

Multi-Session Workflows: Purpose-built to run many concurrent coding-agent sessions on a single machine without resource contention.
Ultra-Low RAM Footprint: ~28 MB baseline for a single session with local embeddings off — several times leaner than comparable harnesses.
Cross-Platform: First-class support for Linux, macOS, and Windows via GitHub Releases with Homebrew and source builds.
Infinite Customizability: Harness internals are exposed for deep tweaking — providers, prompts, memory, and tooling can all be swapped.
Provider-Agnostic: Configure your own LLM providers rather than being locked into one vendor.
Benchmarks Included: Public benchmark suite at jcode.sh/bench so users can compare RAM, boot-up, and session performance against alternatives.
Local Embedding Toggle: Turn local embedding on for retrieval-heavy work or off to minimize resource usage.
Community Support: Active Discord community and dedicated docs site for onboarding and customization help.

Running Ten Agents in Parallel: A developer spins up a coding agent per repo and lets them work in parallel without exhausting RAM.
Low-Resource Machines: Use jcode on older laptops or cloud VMs where heavier harnesses eat too much memory to be practical.
Custom Harness for a Specific Stack: Deeply customize prompts, tools, and providers to match a language or company codebase.
Benchmark-Driven Selection: Teams evaluating agent harnesses use jcode's published metrics to compare performance apples-to-apples.
Self-Hosted Coding Agents: Bring your own LLM provider (local or cloud) to avoid vendor lock-in on a proprietary harness.
