Production frontend monorepo for Mixtape, Crossroads, Catalyst, mobile surfaces, and shared UI packages.
This is the public frontend monorepo for a live production system, shared for technical review. Mixtape has been live since April 2026 with over 99.99% uptime. This frontend repository has 920 commits and is part of a larger Mixtape release constellation that includes Django core, realtime services, ingestion/classification, semantic memory, research, and Puddlejump governance.
Mixtape Release Frontend contains the primary user-facing surfaces for an AI-native collaboration and knowledge-stewardship platform. It includes authenticated Mixtape application views, Crossroads public and product pages, Catalyst ingestion interfaces, writing and publishing workflows, group/member surfaces, and React Native mobile work.
The frontend is built for a product where people, groups, and AI agents collaborate around knowledge over time. The experience work is therefore not just CRUD UI: it includes orientation, curation, review, publishing, semantic-memory surfaces, and operator-heavy ingestion workflows.

The public site for Crossroads Place (crossroads.place), the reference community running on Mixtape: orientation and product pages for Mixtape, Catalyst and Tapestry, plus Group presence pages. See apps/crossroads/README.md for naming (Mixtape is the ecology; Crossroads is its people-and-groups layer).

Catalyst is the knowledge-ingestion and Codex-generation experience. Recent work refactored document ingestion toward a resourceful, operator-assisted pipeline.
The frontend now supports a more deliberate flow: source upload, first-pass inventory, duplicate awareness, section review, operator notes, domain-specific shortcuts, progress visibility, and register/entry browsing. This change supports a 91% token savings in Catalyst document parsing and ingest from the strategy shift alone, while making the human review layer explicit in the product.
Representative area:

For product and UX review:
- Catalyst ingestion page for human/AI workflow design.
- Writing and Dispatch surfaces for editorial workflows.
- Group pages for authenticated community/product structure.
- Crossroads Place pages for public positioning and product storytelling.
For frontend architecture review:
- Shared API client patterns.
- Chakra layout conventions and stable class names on major layout components.
- TanStack Query usage around authenticated data flows.
- App Router organization across authenticated and public surfaces.
This frontend works with:
mixtape-release-core(also public) - Django/DRF backend, Celery tasks, Catalyst ingest, service auth.- Realtime and semantic-memory services for messaging, retrieval, research, and ingestion.
- Puddlejump - governing memory, ADRs, build plans, status notes, and agent handoff discipline.
Across the larger Mixtape release constellation:
mixtape-release-corehas over 680 commits.- Puddlejump has over 990 commits.
- Remaining Mixtape release repositories have over 110 combined commits.
