by Alkera.
A self-hostable, web-based workspace where people and agents collaborate live across shared chats, files, and SQL + Python notebooks.
Agent chats
Teammates and an agent share each chat live. The agent runs in its own sandbox on a machine you choose, with opencode or Claude Code.
Notebooks
Reactive, plain-Python notebooks that people and agents edit together, live. Compatible with marimo, with a renderer for tables and charts.
SQL connections
Connect to any database that is compatible with SQLAlchemy.
Workspaces and compute
Run chats and notebooks on the host machine, or add your own machines over SSH and share them per team.
Organizations and access
Password sign-in, nested teams, invitations and roles, with every authorization decision recorded.
Your own model keys
A model gateway calls Anthropic or OpenAI with your keys, set for the whole instance or per organization. Nothing else leaves your network.
