Scale Capacity

Supported Limits (Safe Production Use)

Resource	Maximum	Notes
Concurrent tabs	100	With request queue
Context file size	10MB	GitHub gist limit
API requests/hour	4,000	Warns at 80%, max 5k
Cache memory	100MB	Per-page, auto-cleanup
Memory per tab	50MB	Stable, no leaks
Storage quota	100KB	Monitor at 90%

Real-World Usage Patterns

Typical User (95%):

• 3-5 tabs, 10-15 insertions/hr, 1-2KB context
• Experience: ⚡ Lightning fast, no issues

Power User (4%):

• 10-20 tabs, 50-100 insertions/hr, 10-100KB context
• Experience: 🚀 Fast with occasional queueing

Edge Case (1%):

• 50+ tabs, 500+ insertions/hr, multi-MB context
• Experience: 🐌 Slower but stable, no failures
