# Luigit request limits

Luigit preflights archive and diff blob headers before decompressing blob data.

| Workload | Limit |
| --- | --- |
| Concurrent expensive diff, patch, archive requests | 2 |
| Archive entries | 10,000 |
| Archive blob and response | 64 MiB |
| Diff snapshot entries | 10,000 |
| Changed files | 5,000 |
| Diff text input | 32 MiB |
| Diff lines per text side | 100,000 |
| Diff rendered or patch output | 32 MiB |
| Individual diff blob | 8 MiB |
| Public refs | 100,000 |
| Refs scanned while finding public refs | 1,000,000 |
| Entry metadata | 4 MiB |
| Path | 16 KiB |

Oversized archive or diff blobs, exhausted aggregate archive or patch budgets, excessive diff line work, and snapshot limits return HTTP 413.

Excess expensive requests return HTTP 429 before repository work begins.

The semaphore permit is owned by background work until it completes, including after client cancellation.

Public ref limits apply after filtering to heads, tags, and notes.

Reference scanning has a separate finite cap so hidden refs cannot consume unbounded work.
