CodeKastenBuild the tools your team works in

Records, apps, workflows and versions in one place. Define a record type and it has lists, forms, an API and agent tools at once.

Get started

Build an app

For developers

Records without a schema migration

Projects, tickets, customers, documents. A type is a definition, and its lists, forms, filters and detail pages are drawn from it.

Versioned like code

Every workspace has branches, commits and merges. Try a change on a branch, look at what it did, merge it or drop it.

Apps you can ship

Build record types in an app workspace, publish a release, and install it wherever it is needed. Upgrades come as new releases.

Workflows

Draw what should happen when a record changes, on a schedule or on a webhook. Workflows are data too, and ship in packages.

Made for teams

Roles and groups, a grid of who gets which branch, branches shared with guests, protected branches, chat about any record, mentions, an Inbox, and boards for thinking out loud.

Open to agents and code

A GraphQL endpoint built from your own types, and an MCP server that lets an agent work as the person whose key it holds.
