Why LiteJoin?

You shouldn't need a platform team
for real-time data

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
LiteJoin Studio

The fastest way to build streams

Data engineering without the engineering. Construct real-time pipelines with the comfort and speed of a modern API client.

⚡

APIs to Streams Instantly

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.

🛠️

Reactive SQL

Write standard SQL. Get intelligent autocomplete for your API's JSON schemas. Evaluate joins reactively as data lands.

⏱️

Time Travel Replay

Dragging the timeline pauses the live feed. Rewind, update your SQL, and replay historical drops through your new query. Absolute confidence.
