The AI-native
complete backend solution
One single surface and one AI-first CLI for your entire backend — identity, data, storage, functions, jobs, sites, AI gateway, and more. Run a single local node or a fully component-isolated fleet, and migrate between them without rewriting your project.
Think Supabase + Vercel + Segment + Airbyte + OpenRouter + Step Functions — unified behind one coherent surface. A robust Rust layer of adapters over best-in-class building blocks, so you never reinvent the wheel.
One surface, every primitive
Each capability is exposed through the same consistent, AI-first API and CLI — and they compose with one another.
Identity →
Auth, sessions, API keys, and multi-tenant orgs/teams with roles and permissions built in.
Data →
Relational data and instant APIs over PostgreSQL, with row-level security and smart caching.
Realtime →
Live subscriptions and presence on top of your data — push changes to clients as they happen.
Storage →
Object storage with signed URLs and CDN delivery. S3-compatible or local filesystem.
Functions →
Serverless compute with an adaptable runtime — WASM today, Lambda and Firecracker as you scale.
Jobs →
Scheduled and event-driven workflows with durable execution, retries, and dead-letter queues.
Sites →
Static and dynamic site hosting at the edge, with custom domains and automatic TLS.
AI Gateway →
LLM routing with per-user quotas, residency, and cost controls — the Relai concept, built in.
Connect →
Sync jobs, ETLs, and API calls — a Connector trait composed from Functions, Jobs, Data, and Storage.
Analytics →
Product and usage analytics with an event pipeline — Segment-class, on your own infrastructure.
Vault & Policies →
Encrypted Secret Vault, low-latency Cache, and centralized access Policies — all behind the same surface.
From one node to a fleet
A Reactor cluster scales — and migrates — across six topologies. Components split onto independent infrastructure as you grow, while the Rust abstraction layer lets you move between them without rewriting your project, in any cloud.
Local
Everything in a single process on your laptop. Zero setup, full parity.
Single node
One managed server in the cloud — the whole stack on a single machine.
Database independent
Postgres moves to its own dedicated server for headroom and durability.
Infrastructure independent
Vault, cache, and core services split onto their own scaled tier.
Gateway independent
The edge gateway and AI routing scale on a dedicated layer.
Fully isolated
Every component runs on independent, separately-scaled infrastructure.
Migration between topologies is online and reversible — your project file, data, and APIs stay the same.
Self-host, cloud, or your own cloud
Run the open-source core anywhere, let Reactor Cloud manage the fleet for you, or bring Reactor to your own cloud with enterprise BYOC.

Self-managing, self-healing
Reactor can operate itself. It detects and diagnoses failing components, generates a new version, sandbox-tests it, and — with your authorization — promotes it to production. Full AIDevOps, under human supervision.
Detect
Continuous health checks surface failing or degraded components.
Diagnose
Reactor reasons over telemetry to pinpoint the root cause.
Generate
A new component version is generated to fix the issue.
Sandbox test
The candidate is validated in isolation before it ships.
Promote
With human authorization, the fix is promoted to production.
