Same platform, same mission, new name. Byte Teaching is now Petrios — a name we can build a distinctive, lasting open-source project around.

Everything carries over: your data, your sign-ins, and the full feature set, now under the Petrios family names (Petrios Meet, Petrios Ops, Petrios Recall). For API integrators: new tokens use the pt_ prefix and webhook signatures moved to the X-Petrios-Signature header — recreate tokens and update header checks when you upgrade.

Our abstract has been accepted for poster presentation at the CHESS Conference — Future Ready: Today for Tomorrow — which brings together educators from across children’s healthcare, education, and industry to share learning and showcase innovation.

The conference takes place on Friday 11 September 2026 in Sheffield. If you’re attending, come and find the poster — we’d love to talk about evidence-based teaching operations, open-source infrastructure in the NHS, and where the platform goes next.

Petrios is now API-first: an org-scoped REST API with scoped tokens and an OpenAPI schema, HMAC-signed webhooks for session, attendance, certificate, and slot events, and full self-hosting support — Docker image, SMTP transport, a plain-Postgres migration runner, and an OpenAI-compatible endpoint override so AI can run in-network.

Instances also gained a federation identity: members can export signed, portable teaching records that any other instance — or anyone at all — can verify. A trainee’s teaching history now survives rotating between trusts.

The full platform is on GitHub under AGPL-3.0: scheduling, evidence-based attendance, built-in video, anonymous feedback, certificates, portfolio evidence, and the approval-gated AI ops layer — all of it readable, auditable, and self-hostable.

Star the repo, read the roadmap, open an issue, or pick up a contribution — the spec/ folder documents how every subsystem works so you can be productive on day one.
