This isn't exactly what you're looking for but for just the coding part, I am working on https://www.buildautomaton.com to allow multiple people to participate on a shared coding session. It's also bring your own agent subscription, uses ACP to talk to any agent (Cursor, Claude, Codex, etc), and is end-to-end encrypted for most of your IP.
Looks great, but the pricing model is a challenge for a small team. If there was a generous trial period (for testing) with a lower small team price I might be able to consider it, but it’s hard to justify constantly increasing AI and compute costs (already paying for several model subscriptions, existing orchestration tools… in addition to typical infrastructure)
Thanks for the honest feedback. I'm still playing around with the pricing and trying to get it right.
