Automate Everything

The best developers automate the pain away. Create references to frequently used secrets in Doppler. Then when they need to change, you only need to update them once.

Powerful Automations

Collaborate Together

Your teams' encrypted source of truth. Organize your secrets across projects and environments.

The scary days of sharing secrets over Slack, email, git, zip files, are over. After adding a secret, your team and their apps have it instantly.

Environment management example

Boost Productivity

Like git, the Doppler CLI smartly knows which secrets to fetch based on the project directory you are in. Gone are the futile days of trying to keep ENV files in sync!

$ doppler setup
... select project: billing
... select config: dev_robert
... path: ./services/billing

The Doppler Effect

Loved by hobbyists and forward-thinking companies for transforming their developer experience. It's an honor to share their stories.

"As a Fintech company, security and reliability are paramount. Doppler has been critical in maintaining the integrity of our secrets while being extremely easy to use. It’s easily the best secrets management tool I’ve ever used and integrating it into our CI/CD pipeline was a breeze."

Kenan Pulak

"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 Vercel integration takes that to the next level and allows us to quickly sync our environment variables to all of our Vercel projects with ease."

Zach Waterfield
Senior Software Engineer
On Deck

"As a company in the security and compliance space, security is of paramount importance. We love Doppler, as it gives our engineers a secure way to manage secrets across all our projects in a single hub."

Natasja Nielsen

"One of our favorite developer tools is Doppler! We love them because any member of the team can quickly switch environments to different servers to debug issues quickly."

Boateng Opoku-Yeboah

"Doppler is Snackpass’s trusted store of secrets. Setting up Doppler as our secrets manager across all our dev machines, CI, and production environments was a breeze."

Udit Jain

"Doppler was easy to adopt as a growing team. Recently, we passed through the security benefits Doppler offers to close a large enterprise customer. It has helped us build security best practice into our company and make more money."

Roger Kirkness

"Doppler is solving one of those problems that you don't realize you have until someone shows you the solution, and once they do, you have no idea how you survived without it. I'm not entirely sure what we'd do without Doppler."

Ben Botvinick

"I've used Doppler for several days now and set everything up in Heroku, Netlify, AWS and locally. Really great work. I love every single part of Doppler. Super clever features like branching of configs, references to other secrets etc are thought of in such detail. The setup was a breeze and it's saving us so much time. Amazing product!"

Sascha Metz

"Doppler is a foundational part of our dev, staging, and production infrastructure. Once you start using it, it's hard to go back. Doppler not only manages our secrets, but also various constants we want to share across our fleet. We were accustomed to using similar infrastructure while at Facebook, and we're glad to have Doppler fill that gap without having to build it ourselves."

Ivan Kanevski

"As a small team with limited resources, we have a million things on our plate, and never enough time. Doppler has made it extremely simple to manage our secrets and onboard new employees. That's one less thing to worry about!"

Courtland Allen
Indie Hackers

"Doppler helps me sleep better at night knowing our secrets are managed and safe. As we've scaled and added engineers as well as third party contractors, keeping everyone on the same page and making sure nothing leaks was crucial and with Doppler it was a breeze. Haven't had a single issue with keys since we signed on - which says a lot!"

Abhi Nayar

"Doppler is one of those products that once you start using, you wonder how you functioned without it. It’s a complete no-brainer. While the product is undoubtedly the best in its class, Doppler’s support is par excellence too: because of some idiosyncrasies in our setup we ran into some edge cases. Brian patiently helped me get everything squared away on a Zoom call. 10/10 would use again."
