| Pricing | Open source under Apache-2.0 license. WARM Cloud is in development with usage-based pricing for sync, backup and verification; details to be published at launch.
| Free for one developer with up to 25 source-built services, 50,000 tool calls a month, then $0.20 per thousand. Team plan is $25 per developer per month with 100,000 tool calls per developer a month, pooled, then $0.20 per thousand. Enterprise from $1,500 per month.

- AES-256-GCM encryption at rest with Argon2id key derivation
- Signed audit log with Ed25519 and W3C DID identity
- Secure purge that overwrites deleted data with zeros
- Crash-safe append-only log with checksumming
- Native Rust API with Python HTTP client and Node.js bindings
- MCP server integration for editors and AI agents
- WARM Cloud sync, backup and verification without server access to keys or documents
| - Source-built servers with TypeScript or Python projects
- Remote MCP, OpenAPI, npm package, and container image support
- Per-tool and per-argument access control policies
- Tool definition review and approval workflow
- Content scanning with literal and regex detectors
- Activity tracking and audit trails
- OIDC and SAML 2.0 single sign-on
- SCIM 2.0 provisioning
- Workspace-specific data encryption
- Custom domain publishing with DNS and Cloudflare certification
|

| What makes it different | - Runs entirely locally in your process with no network calls or telemetry
- Encryption at rest built into the open-source engine itself, not an enterprise add-on
- Significantly faster vector search than hnswlib with graph-indexed vertex retrieval
- Signed provenance and verified audit trail using C2PA, COSE and SCITT standards
- Embedded library model eliminates dependency on external services or vendor lock-in
| - One endpoint replaces every client config, eliminating need for each client to store every server and secret
- Coding agent builds the server automatically with no adapter needed
- Credentials held once by Rayrun instead of distributed across clients
- Built-in security review with published controls and audit trails for compliance teams
- Support for multiple service types without writing adapters
