Apollo Cache Manager

Inspect, edit, and manage Apollo Client cache data in real-time from Chrome DevTools

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 Privacy No data is collected. No remote servers. Everything runs locally in your browser. Open Source https://github.com/nicetomyou/apollo-cache-manager
