BearDrive

Runbear

Free

Open-source shared folder that syncs the files your team's AI agents create, with versions, authorship, and shareable links — no server required.

Filesystem-native sharing: The shared surface is your local filesystem, so any AI agent that writes files can participate without a special SDK.
Second-scale sync: Files sync to teammates within seconds of being written, so an agent's output is immediately available to another teammate's agent.
Automatic versioning: Every synced change becomes a version that is kept, attributed to a user or agent, and restorable.
Shareable web view: Every file gets a link you can drop into Slack; teammates open a web view of the file with no install required.
Team history and authorship: See who — or which agent — produced each file and when, across the whole team.
Open source, self-hostable: AGPL-3.0 with the server, teams, history, and links code publicly available on GitHub.

Agent-produced research sharing: An analyst's research agent drops long-form HTML reports into a shared folder; a teammate's agent reads them the next minute.
Design/data handoff: A design or data agent writes assets or CSVs at a stable path so downstream agents pick them up without brittle Slack uploads.
Cross-agent workflows: One agent's output is another agent's input — BearDrive keeps the artifacts and their versions instead of scattering copies.
Team memory for AI work: Teams keep a browsable history of everything their agents have produced, restorable and attributable.
Self-hosted deployments: Regulated teams host BearDrive on their own infra to keep AI-produced files inside their perimeter.
