▸ Decision summary
AgentSky and Murmell both let you run Claude Code, Codex, or other coding agents in the cloud instead of on your laptop, but they solve different jobs. AgentSky is a general-purpose, omnichannel agent host built for one agent working alone over a long stretch, reachable from Slack, WhatsApp, or the CLI. Murmell is a shared coding canvas built specifically for multiple agents and multiple people working on the same repository at once. This compares their pricing, collaboration models, and who each one actually fits.
Pick AgentSky if you want a single always-on agent reachable from Slack or WhatsApp for ongoing work. Pick Murmell if your team is running several coding agents on one repo and merge conflicts are the real problem.
AgentSky
Developer ToolsAgentSky launches a long-running AI agent in one click and keeps it alive in the cloud instead of on your laptop. Pick a harness (Claude Code, Codex, Hermes, or OpenClaw) and a model, and the agent runs in a managed sandbox with full history, reachable from Slack, WhatsApp, Telegram, iMessage, the CLI, or the API. There's no permanent free tier, but sign-up includes a $3 credit and idle agents cost nothing while parked.
Murmell
Developer ToolsMurmell is a browser-based cloud canvas where multiple AI coding agents, Claude Code, Codex, Kimi, and OpenCode, work on the same repository at once without overwriting each other. Each agent claims the files it's about to touch before writing, everyone on a shared link sees the same room in real time, and the work keeps running even after you close your laptop. It's built for developers or small teams running several coding agents in parallel who are tired of merge conflicts and agents dying when the lid closes.
Decision Recommendation Matrix
| Metric | Winner | Vetted Recommendation Analysis |
|---|---|---|
Channel Reach | AgentSky | AgentSky reaches Slack, WhatsApp, iMessage, Telegram, and the CLI; Murmell is limited to its own browser canvas. |
Value for Money | AgentSky | AgentSky's usage-based pricing starts at a $3 credit for a single agent; Murmell's plans start at $39/month regardless of how much you actually use it. |
Agent Harness Support | Tie | Both support four coding agent harnesses today, though the exact lineups differ: Hermes and OpenClaw on AgentSky versus Kimi and OpenCode on Murmell. |
Multi-Agent Collaboration | Murmell | Murmell's path-level file claims and shared canvas are built for multiple agents and people working together on one repo; AgentSky is designed around a single agent at a time. |
Tradeoffs & Limitations
AgentSky Details
▸ Key Strengths
- No lock-in: swap the harness or model mid-task and the agent keeps its full history
- Reachable from seven channels (Slack, WhatsApp, iMessage, Telegram, Discord, web, CLI) with the same agent state
- Clone-to-cloud copies your local Claude Code or Codex config without exposing API keys or session history
▸ Known Sacrifices
- No permanent free tier, just a one-time $3 signup credit before usage billing kicks in
- Pricing is metered by compute-second and token, so costs are harder to predict than a flat subscription
- Built for people already comfortable running Claude Code or Codex, not a beginner-friendly chatbot
Murmell Details
▸ Key Strengths
- Real conflict prevention: agents claim file paths before writing, with a 15-minute default lease and instant release the moment an agent process dies
- Runs Claude Code, Codex, Kimi, and OpenCode on one shared repository, with Hermes coming next
- Anyone with the link can watch a live canvas for free, no account needed
▸ Known Sacrifices
- No permanent free tier: paid plans start at $39/month after a 7-day trial
- Cloud-only, there's no self-hosted option if you want the infrastructure in-house
- File-level claims don't stop two agents from breaking the same contract from opposite ends, so the build can still fail
▸ Concrete Tradeoffs
- 1.
AgentSky: supports Claude Code, Codex, Hermes, and OpenClaw with omnichannel reach, but there's no permanent free tier beyond a one-time $3 credit.
- 2.
AgentSky: built for one agent working alone over a long stretch, not multiple people editing the same repo together.
- 3.
Murmell: solves real multi-agent, multi-person file conflicts with path-level claims, but it's paid-only, from $39/month after a 7-day trial.
- 4.
Murmell: limited to Claude Code, Codex, Kimi, and OpenCode today, with no omnichannel messaging like Slack or WhatsApp.

Quick take
If you need one agent working in the background and reachable from Slack or your phone, AgentSky is built for that. If your actual problem is three coding agents (and three people) fighting over the same repo, Murmell's file-claim system is the one built to fix it.
