Apollo Cache Manager

Apollo Cache Manager is a Chrome DevTools extension that gives you full control over your Apollo Client cache during development.

What it does
- Cache Inspector: Browse all Apollo Client cache entries in a three-panel layout. Search, filter, and group entities by type. Click into any entity to inspect fields, follow cache references, and view nested data. Edit values inline using a schema-aware form or raw JSON editor.
- Draft Editing: Modify multiple cache entities before applying changes. Draft panel tracks all pending edits, letting you review, discard, or apply them in batch — or save them as a reusable scenario.
- Scenarios: Save cache states as named scenarios with descriptions. Apply a scenario with one click to restore a specific cache state. Export and import scenarios as JSON to share setups with your team.
- Schema Loading: Auto-introspects your GraphQL schema via Apollo Client with a two-stage fallback strategy. Alternatively, provide a custom endpoint URL or upload a schema file (JSON introspection or SDL).
- Auto-detection: Automatically detects Apollo Client instances on the page, including apps using connectToDevTools, APOLLO_CLIENT, and the Apollo DevTools symbol.

How to use
- Open DevTools (F12) on any page with Apollo Client
- Navigate to the "Apollo Cache Manager" tab
- Browse the cache, edit entities, and manage scenarios
