# Flowdular > Build business software with AI agents, workflows and custom modules. Flowdular includes accounts, permissions and workspace isolation. Open source and self-hosted. Flowdular is a self-hosted TypeScript foundation for modular business applications. The core is MIT licensed. Coding agents build modules through an approved specification and checked delivery; business agents run workspace tasks with granted tools. ## Product - [Product overview in Markdown](https://flowdular.com/index.md): Product capabilities, local installation, licensing and common questions, generated from the landing page. - [Website](https://flowdular.com/): The interactive product tour. - [A working foundation, not another starter kit.](https://flowdular.com/#platform): Flowdular owns the shared concerns every business platform needs, so each capability you add stays a small, explicit module that people and agents can read, test and replace. - [From a business brief to a pull request, with every step checked.](https://flowdular.com/#how): The sandbox ties design and implementation to an approved specification. One session, one preview, one delivery, whether the change touches one module or five. - [The workshop where features get built.](https://flowdular.com/#sandbox): A separate application that turns a business brief into a reviewed module. It drives the coding agent your team already uses, in an isolated workspace, against the same gates the platform runs. Sample data you attach and recorded adapters let it build on realistic input offline. - [Every module owns its API, data, screens, translations and tests.](https://flowdular.com/#modules): A module is a package with a spec. The scaffold derives endpoints, permissions, migrations and client entry points from it, and validation keeps them in sync for as long as the module lives. - [Start with the shared work. Build what makes your business yours.](https://flowdular.com/#registry): Bring ready-made business capabilities into your application, then adapt them to your processes. Official Modules gives your team reviewed source to build on, so more time goes into the work that sets your business apart. - [The part that decides, kept on a short leash.](https://flowdular.com/#agents): A process can hand a case to an agent. What that agent may reach is not a matter of trust: your workspace binds it to a model provider, narrows its tools, and every run is recorded at a pinned version. - [Say what should happen. Watch it run before it is real.](https://flowdular.com/#workflow): A decision your team keeps making by hand becomes a process you can draw, test on sample data, and only then let near the real thing. Some steps are a rule, some are a person, and some are an agent reading the case and deciding. - [The questions a buyer asks first, answered in the code.](https://flowdular.com/#security): No badges and no promises for a later release. Every line below is a property of the running system, and the file that implements it is in the public repository. - [Built in the open. Owned by you.](https://flowdular.com/#open-source): Flowdular is developed publicly on GitHub. The core is MIT licensed, the roadmap lives in issues, and a change lands only through the same gates the sandbox runs. - [MIT core. Enterprise when you need it.](https://flowdular.com/#licensing): Use the foundation freely, in any company, forever. Add an enterprise agreement when your organization needs support, guarantees and integrations. ## Developer resources - [Source and getting started](https://github.com/flowdular/flowdular): The Flowdular repository and README. - [Coding agent contract](https://github.com/flowdular/flowdular/blob/main/AGENTS.md): Rules for contributing to the platform. - [Architecture](https://github.com/flowdular/flowdular/blob/main/docs/architecture-blueprint.md): Platform and module architecture. - [CLI extensions](https://github.com/flowdular/flowdular/blob/main/docs/cli-extensions.md): Module-owned CLI commands. ## Optional - [License](https://github.com/flowdular/flowdular/blob/main/LICENSE): Core license terms. - [Sitemap](https://flowdular.com/sitemap.xml): Canonical indexable pages.
