Rust-native data and AI platform that runs your Spark code faster
Run existing Spark SQL and DataFrame code through Spark Connect with no rewrites; migrate by swapping the remote URL, and verify readiness with the free scanner.
Sail removes JVM startup, GC pauses, and memory tuning, delivering fast startup and a stateless runtime that can scale to zero.
Prepare data for language, vision, and physical AI using Python libraries for embeddings, model scoring, and multimodal processing at engine speed.
First-class Delta Lake and Iceberg support with deployment in your own cloud account, so data files stay under your control.
Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
