The challenge
What the system needed to solve
Make self-hosted software research fast and repeatable even when an upstream repository is slow or temporarily unavailable.
The build
Engineering decisions
01
Built a searchable, filterable catalog from a pinned upstream dataset.
02
Persisted a reproducible static cache separately from the disposable application container.
03
Added category and platform filters, source freshness checks, and a private authenticated route.
04
Represented the tool in both service directories and Grafana with a feature-level contract test.
Architecture
How the pieces connect
- 1Pinned upstream source
- 2Reproducible catalog cache
- 3Credential-free web application
- 4Authenticated private route
Results
What changed
- Technology research stays available when upstream data is unavailable.
- Updates are reviewable and reproducible rather than fetched unpredictably at request time.
- The application remains simple to rebuild because it owns no irreplaceable user data.
