The purpose-built streaming engine for app developers. Build pipelines visually in LiteJoin Studio, join data securely with standard SQL, and deploy as a single zero-infrastructure binary. No Kafka required.
LiteJoin is purpose-built for app developers who need real-time joins without the operational overhead of stream processing infrastructure.
| LiteJoin | Kafka Streams | Apache Flink | |
|---|---|---|---|
| Setup time | 5 minutes (via Studio) | Hours | Days |
| Infrastructure required | None — single binary | Kafka cluster | Flink + Kafka cluster |
| REST API → Stream | Built in — just add a URL | Requires Kafka Connect | Requires custom source |
| Operational complexity | Run the binary | JVM tuning, partition mgmt | Cluster ops, checkpointing |
| Best for | App Developers | Java backend teams | Data engineering teams |
Data engineering without the engineering. Construct real-time pipelines with the comfort and speed of a modern API client.
Paste a REST endpoint. Studio polls it, diffs the responses, and turns it into a live stream. No webhooks to set up on the source system.
Write standard SQL. Get intelligent autocomplete for your API's JSON schemas. Evaluate joins reactively as data lands.
Dragging the timeline pauses the live feed. Rewind, update your SQL, and replay historical drops through your new query. Absolute confidence.
LiteJoin plugs into your existing data sources and delivers joined results wherever you need them.
Paste any REST endpoint. LiteJoin polls it, diffs responses, and turns it into a live stream.
Consume from Kafka topics with built-in consumer group management and offset tracking.
Stream changes from Postgres via logical replication. Real-time CDC without the complexity.
Change data capture from MySQL binlog and MongoDB change streams.
Coming SoonPush joined results to any HTTP endpoint. Webhooks, APIs, serverless functions.
Server-Sent Events for real-time browser updates. Subscribe from any frontend framework.
Write joined and windowed results directly into Postgres tables.
Stream to analytics warehouses and object storage for long-term retention.
LiteJoin CloudLiteJoin ships an MCP server that turns the engine into an AI-native data platform. Manage pipelines from Claude Code, Cursor, or any MCP-compatible client.
The LiteJoin MCP server exposes every engine capability as a tool that AI models can invoke. Create sources, configure joins, set up windows, and deploy sinks — all through conversation.
Two tiers, one protocol: the Instance MCP manages what's inside a pipeline (sources, joins, windows, sinks). The Control Plane MCP manages the fleet (deploy, monitor, scale) on LiteJoin Cloud.
Works with any MCP-compatible client:
