No bullshit temporary mail service written in Go
burner.kiwi
A temporary email service and API built in Go. No JavaScript. No tracking. No analytics. No bullshit.
Check it out here: https://burner.kiwi
About
Burner.kiwi is designed to be an easy to use, fast, and lightweight temporary mail service. It purposefully doesn't include tracking code, analytics, or advertising and has a beautiful and responsive UI.
For those wanting to self-host, burner.kiwi is designed to be able to run on both AWS Lambda and normal machines. It has several backing database implementations and can be flexibly configured.
There are three production-ready database implementations: DynamoDB, PostgreSQL and SQLite3.
There are also two email implementations: Mailgun and SMTP. SMTP allows you to receive emails directly at no extra cost but will not work with AWS lambda.
This is project still a work in progress, if you think you can help, see the To Do section.
Deploy Your Own!
To run burner.kiwi yourself, you can build a binary or use the official docker image.
Build
To perform a build you must have minify installed, and a working go installation.
make build
Or if you wish to use SQLite3 you must run (this enables CGO for sqlite, the binary produced is capable of connecting to any database):
make build-sqlite
Test
Run all of burner.kiwi's tests locally:
make test
