Launched http://httptoolkit.tech/mock: the latest tool, which adds HTTP rewriting & mocking to existing one-click interception & debugging suite.
Hit #1 on ShowHN, #3 on the HN front page, and #5 on Reddit's r/programming subreddit. Huge flood of traffic, flood of signups, and a serious flow of paid users!
Seems the paid signups is driven by a much clearer free/paid split in the new mocking features, which gives you the essentials for manual rewriting, whilst still differentiating Pro accounts with automation & error simulation tools.
Will be interesting to see how this goes in future, but for now it's all pointing in an excellent direction.
