AimDB turns data contracts into the architecture. Define your schemas once and deploy them unchanged across microcontrollers, edge gateways, Kubernetes and the browser, with explicit, typed migrations when the contract evolves.

AimDB is not a storage engine. It's a typed data plane where the Rust type *is* the wire format.

[![AimDB Live Demo](https://raw.githubusercontent.com/aimdb-dev/aimdb/main/assets/demo.gif)](https://aimdb.dev)

> **[Ask your AI about it](#ask-your-ai-about-your-running-system)**  → Query the live weather mesh in natural language. No install required.

## Why AimDB exists

Most of a distributed system's complexity is translation: IDLs, codegen, serialization glue, schema registries. AimDB deletes that layer by making **the Rust type the contract** — defined once, compiled unchanged from a `no_std` microcontroller to the browser.

- **One type, every tier.** The same struct compiles for firmware and cloud. No conversion layer between them.
- **The buffer defines how data moves.** No manual queue wiring, no separate transport config.
- **No untyped boundaries.** Capabilities, like streaming, migration, observability and connectors, are unlocked by traits.

### The receipts

None of this is roadmap. Every claim is backed by code, tests or committed benchmarks:

- **Data contracts as schema** → the Rust type *is* the wire contract. No IDL, no codegen, [CI cross-compiles](Makefile) unchanged from Cortex-M to WASM.
- **Typed data migrations** → [`migration_chain!`](aimdb-data-contracts/src/migratable.rs) const-validates the chain and works `no_std`, so old and new nodes coexist on the wire.
- **Zero allocation per message** → [allocation baselines](aimdb-bench/data/baselines) across Tokio, Embassy and WASM.
- **Non-blocking producers** → synchronous [`produce()`](aimdb-core/src/typed_api.rs) calls and overwrite semantics on all buffers.
- **Identical buffer contracts across runtimes** → [shared conformance suite](aimdb-core/src/buffer/test_support.rs) validates SPMC Ring, SingleLatest and Mailbox on every adapter.

## Quick start

### Run it locally in 5 min

```bash
cargo new my-aimdb-app && cd my-aimdb-app
cargo add aimdb-core aimdb-tokio-adapter
cargo add tokio --features full
```

Drop this into `src/main.rs`:

```rust
use aimdb_core::{buffer::BufferCfg, AimDbBuilder};
use aimdb_tokio_adapter::{TokioAdapter, TokioRecordRegistrarExt};
use std::sync::Arc;

#[derive(Clone, Debug)]
pub struct Temperature {
    pub celsius: f32,
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
 let runtime = Arc::new(TokioAdapter::new()?);
 let mut builder = AimDbBuilder::new().runtime(runtime);

builder.configure::<Temperature>("temp.indoor", |reg| {
 reg.buffer(BufferCfg::SpmcRing { capacity: 16 })
 .source(|ctx, producer| async move {
 let time = ctx.time();
 for celsius in [21.0, 22.5, 24.1] {
 producer.produce(Temperature { celsius });
 time.sleep_secs(1).await;
 }
 })
 .tap(|ctx, consumer| async move {
 let mut reader = consumer.subscribe();
 while let Ok(t) = reader.recv().await {
 ctx.log().info(&format!("temp: {:.1}°C", t.celsius));
 }
 });
 });

// Build the db and drive every source/tap future until shutdown.
    builder.run().await?;
    Ok(())
}
```

`cargo run` — three temperature readings stream through a typed pipeline. The same code compiles for Embassy on a Cortex-M4 or WASM in the browser by swapping the runtime adapter.

### Run a real weather mesh in less than 30 min

A full MCU → edge → cloud mesh: three weather stations, MQTT broker and a central hub.

```bash
git clone https://github.com/aimdb-dev/aimdb
cd aimdb/examples/weather-mesh-demo
docker compose up
```

## What you get

**Three buffer primitives** that cover most data-movement patterns:

| Buffer | Semantics | Use cases |
| --- | --- | --- |
| [**SPMC Ring**](examples/hello-spmc-ring/) / [**SPMC Ring async**](examples/hello-spmc-ring-async) | Bounded stream with independent consumers | Sensor telemetry, event logs |
| [**SingleLatest**](examples/hello-single-latest) / [**SingleLatest async**](examples/hello-single-latest-async) | Only the current value matters | Feature flags, config, UI state |
| [**Mailbox**](examples/hello-mailbox) / [**async Mailbox**](examples/hello-mailbox-async)| Latest instruction wins | Device commands, actuation, RPC |

**One async API across runtimes.** Tokio, Embassy, WASM — swap the runtime adapter, keep the code. → [How the runtime abstraction works](https://aimdb.dev/blog/building-aimdb-one-async-api)

**Connectors that ship today:** MQTT, KNX, WebSocket, TCP, serial (COBS-framed UART) and Unix domain sockets. Writing your own is one trait impl. → [Connector status](#connectors)

**Optional persistence.** The core is an in-memory data plane; [`aimdb-persistence`](aimdb-persistence) adds `.persist()` with a SQLite backend ([`aimdb-persistence-sqlite`](aimdb-persistence-sqlite)) for records whose history must survive restarts.

## Data contracts: one method per capability

Every capability is an opt-in trait on your schema type: implement it and **exactly one method** appears on the registrar.

| Contract | Implement when… | Verb it unlocks | Tier |
| --- | --- | --- | --- |
| [`Linkable`](https://aimdb.dev/blog/connectors-where-aimdb-meets-the-real-world) | the record is mirrored to/from an endpoint (MQTT, KNX, serial, UDS…) | `.linked_from(url)` / `.linked_to(url)` by default; `*_with(url, codec)` selects JSON/Postcard/custom per link | wire (prod) |
| [`Streamable`](https://aimdb.dev/blog/streamable-crossing-boundaries) | the record streams to browsers as schema-named JSON | ws-connector `.register::<T>()` | wire (prod) |
| [`Migratable`](https://aimdb.dev/blog/schema-migration-without-ceremony) | the schema evolved across versions | `migration_chain!` | wire (prod) |
| `Settable` | sync code outside AimDB sets the value | `SyncProducer::set_value(v)` | wire (prod) |
| `Observable` | the value is worth watching in production | `.observe()` → live last/min/max/mean on `record.list`/`record.get` | introspection (prod, optional) |
| `Simulatable` | the type can generate realistic synthetic data | `.simulate(profile, rng)` | **dev-only — never ships in prod** |

One record type can use different wire formats without runtime codec lookup:

```rust,ignore
use aimdb_data_contracts::{
    link_codecs::{Json, Postcard},
    LinkCodecRegistrarExt,
};

reg.linked_to_with("serial://mcu/temperature", Postcard::<128>);
reg.linked_to_with("mqtt://cloud/temperature", Json);
```

Enable `linkable-json` and/or `linkable-postcard`; the existing `.linked_*`
methods still use the record's `Linkable` implementation. See
[Design 045](docs/design/045-per-link-codec-selection.md) for the bounded
scratch/fallback model.

`Simulatable` is the odd one out: it lives behind the `simulatable` feature (never a default) and switching from simulated to real data is one `#[cfg]` in your app:

```rust
builder.configure::<Temperature>(KEY, |reg| {
 #[cfg(feature = "sim")]
 reg.simulate(profile, rng);
 #[cfg(not(feature = "sim"))]
 reg.source(read_hardware);
});
```

Build with `sim` off and the simulation code is *gone* — no `T::simulate` impls, no `rand`, nothing to audit.

**Old and new nodes coexist.** Migration steps are typed and bidirectional and `migration_chain!` checks the whole chain at compile time — [roundtrip tests](aimdb-data-contracts/tests/migration_roundtrip.rs) cover upgrade *and* downgrade across multi-step chains. It's `no_std` too: even an MCU can accept a payload one schema version behind or downgrade its output for an older peer.

### How the dataflow fits together

A record is written by a `Source`, lands in a typed `Buffer` and fans out to in-process subscribers (`Tap`) and wire-format bridges (`Link` → connector):

```
   Producer                        Consumers
   ────────                        ─────────

┌──────────────┐ ───►  Tap   (in-process subscriber)
   Source  ───► │   Buffer     │
   (typed)      │ SPMC / SL /  │ ───►  Tap   (another subscriber)
                │   Mailbox    │
                └──────────────┘ ───►  Link ──► MQTT / KNX / WS / UDS / serial
```

Types check correctness at compile time, buffers enforce flow semantics at runtime and connectors bridge to your infrastructure, with no integration layer in between. The same code compiles for MCU, edge, cloud or browser — see [Platform Support](#platform-support) below.

## Ask your AI about your running system

AimDB ships an MCP server. Point any MCP-compatible client at a running instance and query it in natural language.

Try it against the live demo — no install required. Add this to your workspace:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "aimdb-weather": {
      "type": "http",
      "url": "http://aimdb.dev/mcp"
    }
  }
}
```

Then ask: *"What's the current temperature in Munich?"*

See the [MCP server docs](tools/aimdb-mcp/) for Claude Desktop and other editors or read the deep dive: [AI-Assisted System Introspection: AimDB Meets the Model Context Protocol](https://aimdb.dev/blog/ai-introspection-with-mcp).
