Party is the secure workspace for your team and agents to build together, in the open. Agent Flows handle 95% of the work and your team can see it all happen and step in when needed to steer. It's built for teams, but caters to the solo builder as well. Use any harness/model - your keys or ours. Cost observability. Memory. Dual-level session sandboxing.
Slack/Teams are comm-first with agents as second-class citizens. Party is work-first and the communication happens where the work is being done. Party is for teams who want to build better and faster than their competition.
