OnePlatform

Open-source data integration, transformation, and app platform.

OnePlatform is a free, open-source alternative to Fivetran + n8n + Retool — combined into one cohesive platform. Ingest data from any source, map it to user-defined ontologies, transform and route it through automated pipelines, and build apps on top of it.

Core Capabilities

  • Data Ingestion — Pull from APIs, databases, files; receive webhooks; stream real-time feeds
  • Ontology Engine — Define data schemas, map source data to your models, auto-generate types and APIs
  • Pipeline Automation — Trigger-based workflows with cron scheduling, event-driven processing, and custom code
  • Code Execution — Run JavaScript/TypeScript (fast, ~1ms via isolated-vm) or Python/Go/etc. (Docker sandbox)
  • App Platform — Build and host apps within the platform using the SDK and code editor
  • API Gateway — Auto-generated REST endpoints with ontology-driven authorization
  • Auth & RBAC — Entity-level, field-level, and row-level permissions driven by the ontology
  • Plugin System — Extend everything via plugins: connectors, transformers, destinations, auth providers
  • Logging & Observability — Distributed tracing (OTEL), metrics (Prometheus), audit trails
  • CLI & SDKs — API-first: everything the UI does is available via REST API, CLI, and TypeScript SDKs

Architecture

9 microservices + shared core library, all running as Docker containers:

Service Purpose
Gateway API routing, rate limiting, auth validation
Auth Users, sessions, OAuth, RBAC
Ingestion Data connectors, webhooks, file uploads
Ontology Schema engine, data mapping, code generation
Pipeline Workflow orchestration, triggers, cron
Execution Sandboxed code execution
App User app hosting and runtime
Logging Centralized logs, audit, metrics
Plugin Plugin lifecycle, hooks, registry

Quick Start

git clone https://github.com/aaron777collins/oneplatform.git
cd oneplatform
cp .env.example .env
docker compose -f docker/docker-compose.yml up -d

The platform will be available at https://localhost (Caddy provides TLS with a self-signed cert for development).

Tech Stack

  • Frontend: React 18, TypeScript, Tailwind CSS v4, shadcn/ui
  • Backend: Hono (TypeScript), Node.js
  • Database: PostgreSQL 16 + PgBouncer
  • Queue/Cache: Redis 7 + BullMQ
  • Sandbox: isolated-vm (JS/TS) + Docker containers (Python/Go/etc.)
  • Observability: OpenTelemetry, Prometheus, Jaeger
  • Monorepo: Turborepo + pnpm workspaces
