The record

Purpose: Collattice is a self-hosted kanban board built for human-agent collaboration.
Deployment: It runs as a single executable with an embedded SQLite database and does not require a database server, containers, or a cloud account.
Agent support: A built-in MCP server exposes board operations to agents over Streamable HTTP.
Live updates: Server-Sent Events stream board changes to connected clients in real time.
Board features: The board supports drag-and-drop cards and lanes, Markdown descriptions and comments, cross-board search, labels, archiving, and dark and light themes.
Integrations: Outbound webhooks can send selected board events to registered URLs, with optional signing secrets and delivery logs.
REST API: The project documents a REST API alongside its MCP tools for managing boards, cards, users, and webhooks.
Attachments: Browser uploads support files up to 5 MB, while API uploads support files up to 50 MB.
Security: Webhook delivery to private and internal network addresses is blocked by default, with loopback, link-local, and cloud metadata addresses remaining blocked even when the private-network option is enabled.
Authentication: The application generates an administrator auth key on first run, and users receive keys for authentication.
Platforms: Release downloads are listed for Windows 64-bit, macOS Apple Silicon and Intel, and Linux 64-bit and ARM64.
