Doppler is a highly scalable secrets manager designed to not only be secure but also improve the productivity of your engineers. Starting today you can do away with env files, hardcoded secrets, and copy-pasted credentials. Doppler was designed to bring a great experience no matter if you are doing local development or in production. Watch our short video on how the Doppler integration works:

Doppler has helped us drastically improve the developer experience at On Deck by having a single source of truth for all our environment variables. The integration takes that to the next level and allows us to sync our environment variables to our Vercel projects. — Zach Waterfield, Senior Software Engineer at On Deck
