Choose Superblocks
If you want an AI builder for internal apps, with enterprise integrations and the option to run it in your own cloud.
Internal-tool platforms
Flex vs Superblocks
Internal tools, product changes, or both?

Which should you choose?
Choose Flex
If you want your operations team building tools on approved production data and your designers improving your existing product, all through the same service.
An operations dashboard and a change to your customer-facing product are different jobs. Flex lets your team do both.
How it works
Starting a project
Superblocks
Build with Clark or import a working prototype and continue developing it in Superblocks.
Flex
Start a Hosted App for an internal tool, or connect the repository of the product you want to change.
Connecting data
Superblocks
Administrators set up integrations and data access for the people building and using the apps.
Flex
Your engineers connect the database and decide what the app can access. Your team can then build tools using that approved data.
Reviewing changes
Superblocks
Before sharing the app, administrators configure its connections to company systems and who can use them.
Flex
Your designer or product manager tries the change in a live preview. Engineering reviews the code before it goes into your product.
Publishing
Superblocks
Superblocks offers cloud, Hybrid and Cloud-Prem deployment options.
Flex
Share your internal tool through Hosted Apps. For an existing product, use your normal release process.

Maintaining it
Superblocks
Keep developing the app in Superblocks. Administrators manage its integrations and the people allowed to use it.
Flex
Come back to the same app or repository for the next change. Your engineers still review changes to product code and manage access to production data.
Pricing
Superblocks
Superblocks pricing includes a base plan, AI allowances and charges for hosted apps. The number of apps you run matters as well as the AI you use to build them.
Flex
You pay for Flex and the AI you use. With self-hosting, you bring your own model keys and pay for the servers running your previews and apps. Your engineers set up and maintain those servers. Flex hosting takes that server work off your team.
See the linked pricing pages for current prices and plan limits.
Your code and your app
Superblocks says you own the code and can export React apps. Flex keeps Hosted Apps source in Git. Neither exporting code nor cloning a repository moves the connected company systems or their access permissions.

Need an internal tool on production data?
With Hosted Apps, your team builds internal tools using production data engineering has approved. Access controls and governance are built in. You can let Flex host the environment or run it yourself.
Your engineers connect PostgreSQL or ClickHouse, supply the credentials and decide which environment an app can use. Connecting another database or service may need engineering work.
