Clone-and-run harnesses that own sandboxes, state, and multi-agent wiring under any coding agent

owainlewis

Minimalist Go multi-agent coding harness with visible plans, parallel subagents, sandbox-first tools, and a single native binary.

Use caseUse it to drive repo tasks from inspection through tests and review in one terminal without a heavy plugin stack.

mindfold-ai

Repo-native engineering harness that persists specs, task PRDs, journals, and multi-platform agent hooks so sessions stop starting from zero.

Use caseUse it to inject scoped conventions and task context into any coding agent across a monorepo team.

aden-hive

Production multi-agent runtime where a Queen pilots work then fans out worker clones with crash-safe state, cost limits, and human oversight.

Use caseUse it to turn a business outcome into a colony of long-running agents with shared ledger and park/resume.

agentcage

Defense-in-depth proxy sandbox with default-deny egress, zero-leak secret placeholders, TLS inspection, and multi-backend isolation.

Use caseUse it to run any coding agent behind an inspecting gateway so real keys never enter the cage and only allowlisted domains resolve.

aannoo

Rust CLI that lets heterogeneous coding agents message, watch, spawn, fork, and subscribe across real terminals without changing how you launch them.

Use caseUse it to wire Claude, Codex, Pi, and others as each other's subagents with collision detection and a TUI dashboard.

dev-amjad-shaikh

Durable LangGraph-style agent runtime in Rust with checkpointed super-steps, WASM nodes, remote workers, and a single static server binary.

Use caseUse it to run production graphs with fork/replay, Flight Recorder journals, and Python/TS clients talking HTTP/SSE.

runxhq

Governed runtime under skills and graphs that admits each act under narrowing authority, injects credentials off-prompt, and seals verifiable receipts.

Use caseUse it to execute portable SKILL.md workflows with policy and audit without embedding another agent framework.

jskswamy

One-command OS-native sandbox launcher for any coding agent with Seatbelt/Landlock, capability unlocks, encrypted secrets, and live statusline.

Use caseUse it to stop babysitting allow prompts while still unlocking docker/k8s/gcp only when a project needs them.

enmanuelmag

Provider-agnostic scaffolding with task backlog, five-role workflow, health gate, MCP server, and persistent action logs.

Use caseUse it to force Lead/Explorer/Builder/Reviewer roles and a green health check before any agent touches the codebase.

algorithmicsuperintelligence

Open-source AlphaEvolve-style evolutionary coding agent that iteratively refines algorithms with ensembles and evaluation loops.

Use caseUse it to clone a research-origin optimizer loop that discovers stronger code under fixed eval harnesses.

open-multi-agent

Self-hosted TypeScript runtime where consequential actions wait for durable approvals and every run leaves a byte-verifiable record.

Use caseUse it to run organizational agents you can own, approve offline, and audit without a hosted control plane.

crestalnetwork

Self-hosted cloud agent cluster that manages collaborative teams of agents around intents rather than one-off chats.

Use caseUse it to stand up a multi-agent cluster that keeps working a shared intent with local ownership of state.

cloudflare

Open-source vibe-coding platform kit built entirely on the Cloudflare stack so you can host your own agent coding surface.

Use caseUse it to clone and run a Cloudflare-native coding agent platform instead of renting a closed IDE agent.

originoneai

Local Rust CLI and MCP that indexes project Markdown/YAML, records checkpoints, and compiles bounded context packets without model calls.

Use caseUse it to hand a new session only the current goal, unfinished work, and next action instead of the whole history.

vilano-ai

Durable BEAM-kernel runtime with disposable TS workers, replay-from-top workflows, leases, and supervised long-lived keyed agents.

Use caseUse it to replace retry soup with deterministic replay and passivation for production agent systems.

0Albiere

Bun-native production agent runtime with Postgres persistence, BullMQ distribution, type-safe tools, and built-in observability.

Use caseUse it to run resilient multi-worker agent loops that survive crashes with full step history in Postgres.

HKUDS

Ultra-light self-hosted personal agent framework with WebUI, memory, MCP, multi-agent delegation, cron, and OpenAI-compatible API.

Use caseUse it to run a small readable core that coordinates helpers, tools, and chat-app gateways on your own box.

fishman

Curated map of portable microVM and container isolation harnesses for coding agents with boot-time and mount comparisons.

Use caseUse it to pick and clone the right microVM or rootless container primitive before wiring your own agent loop.
