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 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 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.

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. |
AgentSky: supports Claude Code, Codex, Hermes, and OpenClaw with omnichannel reach, but there's no permanent free tier beyond a one-time $3 credit.
AgentSky: built for one agent working alone over a long stretch, not multiple people editing the same repo together.
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.
Murmell: limited to Claude Code, Codex, Kimi, and OpenCode today, with no omnichannel messaging like Slack or WhatsApp.
