Latest News
When knowledge goes stale: Selemis explains the need for durable organizational context and presents Kival as its first implementation.
Introducing Kival: Selemis releases Kival 0.1, its first public, open-source self-hosted collaborative knowledge system for organizations.
Products & Services
An open-source, self-hosted collaborative knowledge system for organizations. It lets people and agents create, edit, discuss, connect, version, search, and govern shared knowledge while retaining history, relationships, authorship, provenance, and access controls.
An open-source Rust library for expressive command-line parsing and configuration; Selemis says it grew out of the need for Kival's CLI to serve both people and software without maintaining two interface definitions.
An open-source PostgreSQL-backed durable task library/queue for Rust applications, supporting persisted queues, retries, checkpoints, durable sleeps, cancellation state, results, and idempotency keys.
Market Position
Selemis positions Kival as a self-hosted alternative to fragmented organizational information tools: rather than treating documents as isolated pages, it keeps versions, discussions, relationships, authorship, provenance, and access context connected. Its differentiators are self-hosted ownership, an explicit knowledge model, and first-class participation by both people and agents.
