How Pull Request Limits Reduce Noise

·2026.06.19 01:00

Key point

GitHub has introduced a new feature that limits the number of Pull Requests to reduce the burden on open-source maintainers.

Details

As the number of open-source contributors surges, the volume of Pull Requests (PRs) has exploded. Monthly average PRs, which stood at 25 million in January 2023, have now surpassed 90 million, an increase of about 3.6 times. In this process, low-quality PRs have been mixed in, creating a problem of increased review burden for maintainers.

In response, GitHub has introduced a Pull Request limits feature. Its key characteristics are as follows:

  • Task limits: You can set the number of PRs that users without write access can have open at the same time.
  • Includes AI agents: PRs created by Copilot or other AI agents are also included in the limit count.
  • Exception settings: Trusted contributors can be registered on a Bypass list that excludes them from the limit.
  • Draft exclusion: PRs in Draft status are not included in the limit count.

This measure aims to create an environment where maintainers can focus on reviews, and to encourage contributors to manage the quality of their PRs according to their own priorities.
