Nebula
Nebula is now a shared workspace where people and AI agents sit in the same channels: you post a goal, its orchestrator splits the work between Claude Code, Codex and its own agents, and the team reviews the result together. It makes most sense for small teams that already pay for coding agents and want them working alongside colleagues rather than in separate terminals; at $25 a seat for everyone, including the owner, it is a poor fit for a solo user who only wants an automation runner.
Pros
- Bring-your-own Claude, ChatGPT, Codex, Gemini CLI or Cursor CLI agents at no extra Nebula charge
- Messaging, calls, web research and a cloud computer included in the seat price
- Desktop apps for Mac, Windows and Linux plus iPhone, Android and a CLI
- Credits pause for top-up approval instead of running up an unexpected bill
Cons
- The free workspace is gone; evaluation is a 7-day trial
- Every member, including the owner, needs a $25 seat
- Nebula's own agents draw on separate credits, so heavy use costs more than the seat price
