Overview
HOP Core brings together many of the common components necessary for building standalone agent apps. These include:
- DITA validation and creation tools
- Authentication
- UI framework
- User and organizations
- API connection patterns for Heretto and AI providers
By starting a project with HOP Core, you’ll be able to rely on common capabilities, reducing your effort and tokens to build a new project. Additionally, HOP Core is AI-scanned periodically for security vulnerabilities. But leveraging HOP Core as a framework, you’ll need to spend less time scannind and resolving security issues.

Releases
HOP Core ships frequently, and even small releases can carry changes that matter for apps built on the framework. Each release is captured here as a release note rather than a separate blog post.
0.1.9 — 2026-09-28
Made hop-ui components “zoneless-safe” by adding ChangeDetectorRef.markForCheck() calls in HTTP callbacks, and added a hop-doctor check for zoneless compatibility. Apps running Angular in zoneless mode should pick this up to keep views updating correctly.
0.1.8 — 2026-09-28
Replaced the deprecated datetime.utcnow() with datetime.now(timezone.utc) across authentication, token generation, SSO, password reset, and logging. This removes deprecation warnings and keeps timestamps timezone-aware for downstream apps.
0.1.7 — 2026-09-25
Added the missing Save button to the Reference URLs tab so agent reference URLs can be saved from the UI.
0.1.6 — 2026-09-25
Upgraded the framework to Angular 22. Apps built on HOP Core should plan to align their Angular version accordingly.
0.1.5 — 2026-09-25
Implemented DITA topic to HTML rendering and improved the table UI widget.
0.1.4 — 2026-09-23
Added the agent reference URLs feature, letting agents read from configured web sources, and improved the agent editor UX with per-tab save buttons.
0.1.3 — 2026-08-27
Fixed organization validation in single-org register mode, enhanced hop-doctor and its documentation, and corrected migration guidance.
0.1.2 — 2026-08-25
Introduced the hop-doctor CLI tool for integration auditing, added a release verification process, and published the AGENTS.md integration checklist.
0.1.1 — 2026-08-21
Packaged the hop-ui theme stylesheets inside the npm distribution.
