What is ClassroomIO?

Pre-1.0 open-source LMS in a security-hardening sprint after a wave of disclosed CVEs.

ClassroomIO is an early-stage (0.2.x) open-source learning platform. The recent release log is dominated by security work: stored XSS via SVG upload, email-verification bypass vectors, and a full migration of client-side database calls to server-side authenticated endpoints with role-based filtering — three security releases inside a single week in early December 2025. The January 2026 patch is an unrelated content-save data-loss bug.

What is Code.org?

Code.org readies Hour of AI 2026 with Sprite Lab 2 projects and an Adaptive finish flow.

Code.org's November 12 and 13 builds prepare the 2026 Hour of AI activity: a project type, display art, a freeplay dialog and finish dialog, and Sprite Lab 2 sharing, project pictures and image uploads. Adaptive gets a finish flow with stats tiles, a warning before rebuilding a project with work in it, accessibility fixes and configurable model-call timeouts. The AI gateway fallback now allows international use of the Adaptive tutorial.

ClassroomIO vs Code.org: editorial side-by-side

C0.0

Pre-1.0 open-source LMS in a security-hardening sprint after a wave of disclosed CVEs.

◆ Current state

ClassroomIO is an early-stage (0.2.x) open-source learning platform. The recent release log is dominated by security work: stored XSS via SVG upload, email-verification bypass vectors, and a full migration of client-side database calls to server-side authenticated endpoints with role-based filtering — three security releases inside a single week in early December 2025. The January 2026 patch is an unrelated content-save data-loss bug.

◆ Where it's heading

The product has just walked through a security maturity gate. Moving from client-side DB access to a server-side API with auth middleware is a foundational change, not a cleanup — it implies the previous architecture wasn't safe to grow on. After it, the cadence drops to small bug fixes, which fits a team catching its breath after structural rework. There's no visible product-direction work yet (no new features, no AI, no integrations).

◆ Prediction

Once the team is confident in the new server-side architecture, expect the next visible work to swing back to features — likely course-builder or learner-flow improvements that the prior architecture made hard. Another security release is possible but less likely given how comprehensive 0.2.8 was.

5.0

Code.org readies Hour of AI 2026 with Sprite Lab 2 projects and an Adaptive finish flow.

◆ Current state

Code.org's November 12 and 13 builds prepare the 2026 Hour of AI activity: a project type, display art, a freeplay dialog and finish dialog, and Sprite Lab 2 sharing, project pictures and image uploads. Adaptive gets a finish flow with stats tiles, a warning before rebuilding a project with work in it, accessibility fixes and configurable model-call timeouts. The AI gateway fallback now allows international use of the Adaptive tutorial.

◆ Where it's heading

After switching Adaptive to Gemini 3 and adding OpenAI models to AI Chat Lab on November 8, the team has moved to shipping the student-facing pieces for Hour of AI in December. Sprite Lab 2 is being finished as the activity's main canvas, and Adaptive is being hardened with timeouts, fallbacks and accessibility work ahead of classroom traffic.

◆ Prediction

Builds through early December will likely keep finishing the Hour of AI 2026 activity and scaling the AI gateway for classroom load.
