What problem it solves

Modern websites may serve different content to browsers, crawlers, and other client environments, making it difficult to inspect access controls, headers, and delivery behavior. Developers need a way to request and modify proxied responses for legitimate testing, research, and quality assurance.

Key features

• Response and request modification — Rules can modify response headers, requested URLs, and page content through domain-based rulesets. Rulesets may be YAML files, directories of YAML files, or URLs.

  Source: README, rulesets

• Custom code injection — HTML, CSS, and JavaScript can be removed or injected into pages at selected positions. Rules can also use regular expressions to replace matching markup.

  Source: README

• Client environment emulation — The proxy supports a custom user agent and forwarded IP address, allowing requests to emulate different client environments.

• Browser, API, and raw access — Pages can be opened through the browser interface or direct proxy paths, with dedicated API and raw HTML access.

  Source: README

• Deployment and access controls — The project includes Docker, Docker Compose, Helm, and binary deployment options. Basic authentication, access logs, and domain allowlists are available for controlling access.

Quick start

Copied verbatim from the project's README.

docker run -p 8080:8080 -d --env RULESET=https://raw.githubusercontent.com/everywall/ladder-rules/main/ruleset.yaml --name ladder ghcr.io/everywall/ladder:latest

curl -X GET "http://localhost:8080/api/https://www.example.com"

Who it may suit

Inference: this may suit developers, researchers, and publishers who need to test paywall configurations, response headers, client-specific content delivery, or custom proxy rulesets.

Topics to discuss

• Which domain-specific response and URL modification rules would be most useful for your testing workflow?

• How should rulesets be structured to support reproducible testing and safe domain allowlisting?

• Which FlareSolverr integration scenarios should receive clearer configuration guidance?
