Serverless Development for Web Services
Build custom functions for Google Sheets, Gmail, Dropbox, and other web services with the best Python and Node.js libraries for the job.


Go from function to functional
Coding a function is only the start. To productionalize functions for many web services, you need a host of complementary functionality. Flex.io provides the prototyping + OAuth access + orchestration tools to take you from function to production.
Deploy functions for the web services you use every day
Google Sheets + Pandas
Take that robust data science toolkit you've carefully built and apply it directly to data in Google Sheets. Flex.io handles refreshing the OAuth tokens and allows you to quickly put Pandas functions into production in the cloud in a few minutes.


Amazon S3 + D3Node
Setting up a batch job to pre-render data visualizations is a lot easier when you can preview the results and fix issues directly. Flex.io provides a web-based UI to prototype and test D3Node functions and simplifies their deployment as well.
Dropbox + PyPDF2
Processing files in cloud storage doesn't need to be a pain. Want to use PyPDF2 to extract the title and author of new PDF files added to Dropbox? Sure thing. Flex.io let's you create automated services for cloud storage services using your own custom functions.


Save development time and cost
Extending web services shouldn't take a lot of time. Knocking out a function for this is the easy part. But it can take a range of additional infrastructure to put even a single function into production.
There's no need to reinvent the wheel. Flex.io can help you move faster and save substantial effort by handling library complexities and providing services for OAuth, notifications, scheduling, local storage, and other common infrastructure needs.
Designed for developers
In production in minutes
Bring your own functions and use Flex.io to run them inline with other helper tasks. Splitting a complex process into simpler parts means faster time to deployment.
Flexible execution and scheduling
Run functions on demand, at a scheduled time or via an API call. Or set up a webhook to trigger a function in response to events in your app or on the web.
Pre-built connector library
Quickly setup connections and let Flex.io handle OAuth complexities such as refresh tokens. Save time using the Flex.io connector library with pre-packaged functions for accessing common file systems.
Easy version control and management
Flex.io works seamlessly with your existing GitHub repos. Build functions in your IDE and use source control to fork, customize and manage logic; call your function from Flex.io to run it.
Out-of-the-box local storage
Take advantage of local storage automatically provisioned with every account. Build functions that persist, aggregate and compare data from different sources or multiple API calls.
Zero server maintenance
Deploy functions instantly without provisioning and managing servers. Focus on your core code, not the scalability or reliability of server infrastructure.
