Supported platforms
macOS and Linux for the native C SDK and CLI; Windows currently uses the native serial path. The web and portal applications are served from Vercel.
Buying Saar
What you can rely on,
stated plainly.
Platforms, deployment, data handling, support and release status — with the gaps named rather than glossed over. Nothing here is a certification, an SLA or customer evidence.
Deployment options
Embed the checked C11 library, script the native CLI, or call the TypeScript API from Node.js. Platform qualification is part of each evaluation, not an assumption.
Security & data handling
Envelope and stream SHA-256 checks detect corruption; they are not encryption or sender identity. The planner uploads nothing, and the portal live comparison sends at most 32 KiB only when you explicitly run it. Do not submit confidential data.
Support expectations
Evaluation support, data handling and any commercial terms are agreed in writing with HEOSSI before work begins. No SLAs, certifications or 24/7 terms are offered on the public site.
Release & version status
TypeScript codec 1.3.0 is an unreleased candidate; native SDK 1.2.0 is locally tested. Objects are SAAR v7 (compact binary) with v6 stored. No signed public artifact is published yet.
Design-partner programme
Work with us on a first deployment.
We are opening a small, clearly labelled design-partner programme for teams with a real workload and acceptance criteria. This is not a customer list, and no logos or testimonials are shown because none are verified.
- Bring a representative corpus and your success criteria.
- Evaluate against your current codec using your own tests.
- Agree data handling, support and any commercial terms in writing.
