Quine
What Quine is
Quine is an open-source platform that processes event streams into connected graph data, monitors the graph for patterns and can send results to other systems. Standing queries stay active as events arrive and run configured actions when a complete match appears. Documented inputs include Kafka, Kinesis, files, S3, SQS, server-sent events, WebSockets and reactive streams. Results can be routed to Kafka, Kinesis, SNS, HTTP webhooks, files, Slack or Cypher queries. Quine supports Cypher graph queries and also documents Gremlin. Its Exploration UI offers an interactive canvas for examining streaming event data. The free Open Source edition is available as Docker, an executable JAR or source code; graph size depends on storage capacity, and the executable requires Java JRE 11 or newer. Quine Enterprise adds clustering, high availability with standby nodes and failover, access controls, identity-provider integration, audit logging, tenant isolation and professional support. Standing-query delivery is best effort, so results can be missed when a queue fills, an output fails or the process restarts.
Who it suits
Quine suits developers and teams that need to turn incoming event streams into graph data and trigger actions when patterns match. The Enterprise edition is aimed at organizations needing clustering, high availability and security controls.
What it does well
- Open-source edition costs nothing
- Accepts a range of documented streaming inputs
- Routes results to messaging, webhooks and files
- Supports Cypher and Gremlin
- Enterprise adds clustering and high availability
What to know first
- Graph size is limited by storage capacity
- Executable requires Java JRE 11 or newer
- Standing-query outputs are best effort
Limits
Quine Open Source graph size depends on storage capacity. Standing-query results use best-effort delivery and may be lost when queues fill, an output fails, or the process restarts.
Plans
| Plan | Billed and limits | Price |
|---|---|---|
| Quine Open Source | Open source · Docker, executable JAR, or source code · Storage capacity limits graph size | Free |
| Quine Enterprise | Commercial edition · Horizontal scaling, high availability, enterprise controls, professional support | On request |

Getting started
- Open the Quine website
- Choose Docker, the executable JAR, or source-code distribution
- For the executable, provide Java JRE 11 or newer
- Deploy through an API, on Linux, as self-hosted software, or on the web
- Connect documented ingest sources and configure standing queries
Verdict
Quine combines streaming graph processing with continuously evaluated queries and a broad set of documented inputs and outputs. Its best-effort delivery limit matters when missed results would be consequential.
