Free tools for Rails developers

Small, focused utilities for everyday Rails work, free and with nothing to install.

Cron schedule builder

Write a Rails schedule once, take away crontab, whenever and recurring-job syntax.

Paste a curl command from an API doc and take away the Net::HTTP and Faraday calls that make the same request.

Decode a token, read its claims, and take away the ruby-jwt call that verifies it.

Read the robots.txt of any site and see exactly which rule allows or blocks a path.

Check the CORS headers of a Rails endpoint and get the rack-cors block that fixes them.

Trace the redirect chain of any URL, then look up any status code with its Rack symbol, reason phrase and Rails usage.

Preview the og: tags on any URL and get the Slim or ERB block that emits them.

Read a .har export request by request, against the Rails app that served it.

Mark up a screenshot before it goes into an issue, and keep the file on your own machine.

Parse a user agent string, and read the same values out of request.user_agent in Rails.

Trim a screen recording and write a GIF, entirely in this tab.

Get a public URL a provider can reach, read exactly what it sent, and copy the Rails route and action that would receive it.

Cover a face, a key or a name in a picture and save the masked copy.
