Quiet Tools makes browser extensions that do one job each. They have no account, no server and no analytics, and nothing you do with them leaves your browser.
Request and response headers
Set, append or remove HTTP request and response headers, with profiles for each environment and URL filters that decide where they apply. Send a token to a staging API, test CORS or strip a header. Headwise imports your ModHeader setup.
Free. Headwise Pro adds response mocks and redirects.
Screen recorder
Record your screen, a window or a tab, with your microphone and the tab or system sound. Record as often and as long as you like, with no watermark and no account. Nothing is uploaded, and recordings stay in your browser until you download or delete them.
Free, with no limits.
