About Ladder

Ladder is a self-hosted HTTP web proxy described as an alternative to 12ft.io and 1ft.io. It is presented as a developer tool for testing and analyzing paywall implementations and content delivery behavior by simulating different client environments, such as browsers and crawlers.

It can remove or modify CORS and other response headers, inject or remove page code, and apply domain-based rulesets to modify responses or requested URLs.
