By Kevin Vera · October 3, 2026 · [Comparisons](https://corkcli.com/blog/c/comparisons) · 7 min read How is Cork different from HumanLayer? HumanLayer is "a multiplayer coding agent IDE and cloud": it runs many agent sessions in parallel on your laptop or in cloud daemons, organizes them into worktrees and workspaces, and walks your team through a structured research, design and plan workflow with comments that feed back to agents. Cork does not run agents or give you an IDE. It sits underneath whatever runs them and keeps parallel agents, and the people behind them, from overwriting each other on the same code, while briefing each agent on the code it is about to touch. HumanLayer organizes the work; Cork coordinates the edits. ## Cork vs HumanLayer at a glance | Topic | Cork | HumanLayer (as of October 2026) | |---|---|---| | What it is | [Coordination layer](https://corkcli.com/blog/coordination-layer-ai-coding-agents) for parallel AI coding agents on one codebase | Multiplayer coding agent IDE and cloud | | Where agents run | Where they already run, on your machine | A local daemon on your laptop, or cloud daemons for long-running work | | Agents covered | Claude Code, Codex, Cursor (hooks), plus any MCP client | "Claude Code, Codex, Copilot, Fireworks," with more added | | What is shared | Live edits, signatures, callers, recent changes, notes anchored to code | Agent sessions, plan artifacts and code diffs in one place for the team | | Conflict handling | Write gate holds edits against code another agent is changing; [semantic lint](https://corkcli.com/blog/semantic-lint) | Sessions isolated in worktrees; we could not verify cross-session edit coordination | | Workflow | None imposed | Structured QRSPI flow with team checkpoints and comment-driven design review | | Install | `curl -fsSL https://corkcli.com/install.sh \| sh` | `brew install humanlayer/humanlayer/humanlayer` | | Open source | Not covered here; Cork Free runs locally with no account | "Not yet," per its site | | Pricing | Free (local, and 10 agent hours a month in the cloud); $20 a month per 100 agent hours, pooled | Starter free (3 members, 200 sessions/mo); Pro $100/user/mo; Enterprise custom | ## What is HumanLayer? HumanLayer (YC F24) describes itself as "a multiplayer coding agent IDE and cloud that works seamlessly from your workstation to anywhere you want to run background agents." Its homepage says "a local daemon runs many Agent sessions in parallel on your laptop," supports multi-repo workspaces and worktrees, and lets you "spin up cloud daemons for long-running work" that keep going when you close your laptop. For teams, HumanLayer brings "agent sessions, plan artifacts, and code diffs together in one place," with comment-driven design review where "comments and decisions feed straight back to the agents." Its workflow moves through questions, research, design, structure, plan and implement, with team checkpoints. It supports Claude Code, Codex, Copilot and Fireworks, and installs via Homebrew. On open source, its site says "not yet," with plans to open some building blocks. ## What is Cork? Cork (corkcli.com, by Lithometric) keeps several AI coding agents, and the people running them, from overwriting each other on one codebase, and hands each agent what the others already learned. It does not run agents or host machines. Hooks in Claude Code, Codex and Cursor run the protocol with no extra model calls, and an MCP server (https://mcp.corkcli.com) serves any MCP client: - **Briefing:** exact signatures, callers and recent changes of the code an agent is about to touch. - **Live awareness:** a teammate's rename or new signature reaches your agent on its next step. - **[Write gate](https://corkcli.com/blog/write-gate):** an edit against code another agent is changing right now is held until your agent has their version. - **Semantic lint:** renames and signature changes become rules your agents are checked against. - **Landing:** `git push` becomes one step that rebases onto teammates' commits, reruns tests and pushes. - **Agent messaging** and MCP tools (get_symbol, blast_radius, recap, remember/recall), plus a code graph and team dashboard on cloud plans. ## Where HumanLayer stands out - **It runs your agents.** A local daemon handles many parallel sessions, and cloud daemons keep work going remotely. Cork does neither. - **A full team workflow.** The structured research, design and plan stages, with human checkpoints, give teams a shared method, not just shared tooling. - **Review before code.** Comment-driven design review on plan artifacts lets people steer agents before implementation. - **Multi-repo workspaces and worktrees** keep parallel sessions isolated by default. - **Broad agent and provider support,** including Copilot and Fireworks. ## Where Cork wins - **Worktrees isolate; they do not coordinate.** Parallel agents in separate worktrees still collide when their branches meet. Cork's write gate, live awareness and semantic lint catch agent merge conflicts while agents are still editing, and landing rebases and retests on push. - **No new IDE or workflow.** Teammates keep Claude Code, Codex or Cursor as they are; Cork installs with one command for every repo on the machine. - **Code-level briefings.** Each agent arrives knowing the exact signatures and callers it will touch. In Cork's benchmark (12 Claude Code agents at once on one repository, hard tasks), agents with Cork used 53% fewer tokens than the same agents without it. - **Price.** Cork bills pooled agent hours, not seats ($20 a month per 100 hours across the workspace), and Cork Free keeps everything on one machine with no account. ## Can you use both? Yes, and this is a natural pairing. HumanLayer runs multiple Claude Code agents in parallel and gives the team a place to plan and review. Cork addresses the gap that remains: those parallel sessions, and teammates' sessions on other machines, editing the same functions. Because Cork's hooks attach to Claude Code and Codex where they run, it should be able to sit under agents HumanLayer launches locally; we have not verified this with HumanLayer's daemon or cloud daemons, so test it on your setup. ## Pricing compared HumanLayer Starter is free for up to 3 team members and 200 sessions per month. Pro is $100 per user per month with unlimited tasks and sessions, multi-repo workspaces and remote daemons. Enterprise is custom with SSO/SAML, audit logs and on-prem options. Cork Free covers unlimited agents and repos on one machine with no account; Cloud Free is 10 agent hours a month per account (30 bonus hours the first month) with a 30-day history. Beyond that you pay for agent hours, not seats: $20 a month per unit of 100 hours, pooled across the workspace, graduated to $17 (units 11 to 50) and $15 (51 and up), with 15% off a year. Every member is a player, with teammates' machines, prompts matched to code by meaning, shared knowledge and 90-day history. Enterprise starts from about 100 units. ## Bottom line HumanLayer is a place to run and steer many agents as a team, with a defined workflow and cloud workers. Cork is the coordination layer that keeps [parallel AI coding agents](https://corkcli.com/blog/parallel-ai-coding-agents) from overwriting each other, regardless of what launches them. If you want a team agent IDE, HumanLayer is built for it. If your agents already run fine but keep stepping on each other's code, Cork solves that, and it can sit underneath HumanLayer rather than replace it. ## Frequently asked questions ### Is Cork an alternative to HumanLayer? Only partly. HumanLayer is an IDE and cloud for running agents; Cork does not run agents. If what you need is to stop [multiplayer coding agents](https://corkcli.com/blog/multiplayer-coding-agents) from colliding, Cork is the more direct tool. ### Does HumanLayer stop agents from overwriting each other? It isolates sessions with worktrees and brings diffs together for review. We could not verify a feature that coordinates live edits across sessions as of October 2026. ### How much does HumanLayer cost compared with Cork? HumanLayer Pro is $100 per user per month after a free Starter tier for up to 3 members. Cork bills pooled agent hours instead: 10 free a month per account, then $20 a month per 100 hours across the workspace, so the two are not per-person equivalents. ### Is HumanLayer open source? Its site says "not yet," with plans to open-source some building blocks. ### Can I run multiple Claude Code agents with HumanLayer and Cork? HumanLayer is designed to run many Claude Code sessions in parallel, and Cork is designed to coordinate multiple Claude Code agents. We have not tested the combination, but they address different layers. ## Sources Checked October 2026: - - - - ## Related reading - [Cork vs Superconductor: a hosted agent workspace, or coordination for the agents you run](https://corkcli.com/blog/cork-vs-superconductor): Cork vs Superconductor: Superconductor runs coding agents in cloud sandboxes for teams.
