Typhon

A real-time, low-latency ACID database engine for .NET.

Typhon is an embedded database engine built on an ECS (Entity-Component-System) architecture with MVCC snapshot isolation, engineered for microsecond-level performance. It targets workloads that need transactional correctness and tight, predictable latency — real-time simulations, game servers, and in-process analytical/transactional (HTAP-shaped) data.

⚠️ Alpha. This package is published as a prerelease. APIs, on-disk formats, and defaults will change without notice until the first stable release. Not for production use yet.

Fastest way to see it work

Don't start from an empty project. The typhon CLI scaffolds a runnable, already-profiled app:

dotnet tool install --global Typhon.Cli --prerelease
typhon new MyApp && cd MyApp
dotnet run                  # deploys a world shard, ticks the runtime, writes a trace
typhon ui --open-latest     # open that trace in the Workbench profiler
typhon ui --open-db         # browse the database you just created

That gives you a working data model, tick systems, and config-driven profiling — with no code to write and nothing else to install. See the Typhon.Cli package for the scaffolder, the shell, and typhon telemetry (which tunes what gets traced without touching your code).

Install

To add the engine to an existing project:

dotnet add package Typhon --prerelease

Prerelease packages are opt-in — the --prerelease flag (or checking "Include prerelease" in your IDE) is required.

What's in the box

This package bundles the engine's public surface:

Engine — transactions, component tables, B+Tree indexes, storage/persistence, MVCC, the runtime, Subscriptions (replication).
Profiler — the in-box CPU/event profiler APIs.
Schema.Definition — the [Archetype] / component-definition attributes.

It depends on Typhon.Protocol — the Subscriptions wire format and the replication attributes — which a contracts assembly shared with clients can reference alone.

Source generators ship alongside: decorate a partial class with [Archetype] and Typhon generates the strongly-typed, zero-copy component accessors for it at compile time; [Replicated] / [ReplicatedMessage] declare what Subscriptions send.

Serving remote clients

Subscriptions replicate engine state to game clients, browsers and bots. Host the WebSocket endpoint with Typhon.Subscriptions.AspNetCore; clients use Typhon.Client (.NET), @typhondb/client (TypeScript) or the C SDK from the GitHub releases.

Using with an AI coding agent

Typhon is new — it's in no model's training data, so a coding agent will guess a SQL-shaped API by default. Point it at https://doc.typhondb.io/llms.txt (most agent tools probe it automatically), or paste this primer:

Typhon is an ECS database (not SQL). Model data as [Component] blittable structs (≥ 8 bytes, public fields) declared inside a namespace; an archetype is [Archetype] partial class Foo : Archetype<Foo> with public static readonly Comp<T> X = Register<T>();. Open with DatabaseEngine.Open(...); do all writes in using var tx = dbe.CreateQuickTransaction(); … tx.Commit();. Query with tx.Query<Foo>().Where<T>(x => …) (not LINQ); read an entity via tx.Open(id).Read(Foo.X).
