Coming soon. The plugin SDK is available today.

One place to extend Ciaren

Plugins, connectors, and templates, official and community-built, with signed packages and explicit permission disclosure. The marketplace itself is coming soon; the plugin platform it indexes ships in the core today.

Extension points

What the plugin platform can load

The core defines versioned provider contracts for each of these. The marketplace will make them discoverable and installable in one command.

Official plugins

Will be built and maintained by the Ciaren team: reviewed, signed, and compatibility-tested against each release.

Signed & reviewedCompatibility-tested

Community plugins

Nodes and extensions published by the community. Every listing will disclose its permissions and trust signals before you install.

Permission disclosureSource-available

Templates

Starter workflows for common jobs such as classification, regression, clustering, and feature engineering, to adapt instead of starting blank.

ML startersETL recipes

Connectors

Data sources and destinations beyond the built-ins (databases, SaaS APIs, file stores), with credentials kept explicit and local.

DatabasesAPIs & storage

ML model types

New trainable models for the Train nodes' model picker, each with its own hyperparameter form, trained and logged through the core ML pipeline.

ClassifiersRegressors

Planned extension points

Exporters, validators, execution engines, storage backends, and AI providers are defined in the SDK but not wired up yet. They are on the roadmap.

Plugin SDK

The plugin SDK ships today

You don't need the marketplace to extend Ciaren. Build, sign, and install plugins locally with the ciaren-plugin CLI, then publish when the marketplace opens.

Ten extension points
Nodes, connectors, and ML model types run end to end today. Storage, execution, exporters, validators, AI, auth, and licensing are defined as versioned contracts for later.
Signed packages
Plugins ship as .ciarenplugin archives with Ed25519 signatures and explicit permission disclosure, so users see what a plugin can touch before installing.
Apache-2.0 SDK
The plugin API is Apache-2.0 licensed, so you can build open-source, internal, or commercial plugins on top of the AGPL core.
