TessariDB

The stack around the model, in one store.

Records, search, vectors, graphs, queues, topics, files, geometry and sealed secrets: eleven engines over one transactional store, in one Rust binary, on its own storage engine.

An AI product usually ends up running a database, a search engine, a vector index, a cache, a queue, an event log and somewhere for files, with no transaction across any of them. TessariDB is one store that does all of those jobs on the same records, under one snapshot, in one language. Not the fastest at any single job; enough at all of them, and nothing to keep in step.

The database. Eleven engines, one transaction, a flexible cluster — sharding, multi-master, automatic failover — on its own engine, TessariKV.

Repository · Site · Docs · 0.39.6

The heart of TessariDB: an embedded key-value storage engine in pure Rust, lock-free first, with a stable file format. TessariDB runs on it from 0.36.0.

Repository · Site · Docs · 0.2.0

S3-compatible object storage in Rust. Metadata in TessariDB, bytes erasure-coded across nodes. Its console signs in through TessariDB OAuth, and the settings its nodes share are kept in TessariDB.

Repository · Site · Docs · 0.8.1

Sign-in for your own applications: an OAuth 2.1 authorization server and OpenID provider in Rust, with every piece of its state in TessariDB. Passkeys, passwords with an authenticator app, consent, and an account page where users see and end their sessions and grants, in one binary with its admin panel.

Repository · Site · Docs · 0.3.0: the admin API answers the subject a sector knows an account by

Goals, plans, tasks and what each agent remembers, as queryable records. CLI, REST and MCP.

Site · Docs · 0.6.2

A password manager for companies. Records are encrypted in the browser and shared by person, team, department or company; the server and TessariDB hold only ciphertext, and every piece of state is in TessariDB.
