Open-source, resource-efficient coding agent harness built for multi-session workflows, deep customizability, and high performance.
Key features
- 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.
Best for
- 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.
Suprbox — Secure Storage for Autonomous AI Agents
Suprbox
Secure, purpose-built memory fabric that mediates document access and stores context and recall vectors for autonomous AI agents.
Key features
- Purpose-Built Memory Fabric: Provides a dedicated storage layer for agent context and state, optimized for storing and recalling contextual information used by autonomous agents.
- Vector Recall & Retrieval: Stores recall vectors and supports fast retrieval of context vectors so agents can access relevant context quickly during execution.
- Document Gateway: Sits between documents and agents to mediate reads and writes, preventing direct, uncontrolled agent access to source documents.
- Runtime Policy Enforcement: Enforces tight, fine-grained policies at execution time to control what agents can read, write, or execute against stored data.
- Execution Isolation: Isolates agent workspaces and memory to reduce risk of cross-agent data leakage and maintain separation between concurrent agent sessions.
- Controlled Context Delivery: Supplies agents only the allowed slices of context and vectors needed for a task, limiting exposure of sensitive information.
- Interposes between documents and autonomous agents to control access
- Purpose-built memory fabric for storing agent context and recall vectors
- Policy-driven execution and enforcement for agent operations
- Workspace isolation to prevent cross-agent data leakage
- Access controls and document-level gating for agents
- Designed for auditability and runtime visibility of agent access patterns
- Integrates with agent workflows to mediate reads/writes to storage
Best for
- Protecting enterprise document stores from autonomous agents by mediating agent access and preventing unauthorized reads of sensitive files.
- Providing persistent agent memory for multi-step workflows where agents need to store and recall contextual vectors across sessions.
- Enforcing runtime access policies for agents operating in regulated industries (finance, healthcare, legal) to maintain compliance and governance.
- Powering secure Retrieval-Augmented Generation (RAG) pipelines where agents retrieve vetted context vectors rather than raw documents.
- Isolating agent workspaces for research or development teams to experiment with agent behaviors without risking cross-project data leaks.
- Coordinating multi-agent systems by centralizing shared context and controlling which agents can access which pieces of memory.
- Prevent autonomous agents from reading or exfiltrating sensitive documents
- Store and manage agent context and memory vectors securely
- Enforce runtime policies for agentic workflows (who/when/how data is accessed)
- Isolate agent workspaces to reduce risk of data bleed between agents
- Provide a secure intermediary for LLMs and bots accessing corporate documents
