Question: I need a solution that enables me to build internal tools with a high degree of code flexibility, using a language like Python.

If you want a system that offers high code flexibility and uses Python, Dropbase is a good option. This service lets you build custom backend operations software quickly without resorting to low-code or no-code approaches. It offers admin panels, data editors, cloud consoles and a notification system, plus integrations with tools you already use. Dropbase offers full code flexibility with Python, and includes tools like an AI Studio for writing and debugging apps and state synchronization. It also can run in your own CI/CD and development tools, so it's a very customizable option.

Another good option is Interval, which marries backend code with UI elements, authentication, audit logs and more. Interval can turn Node.js or Python code into full-fledged web apps, automatically generating UI elements in the browser. It comes with a library of UI components, multi-factor authentication and support for custom roles and permissions. The service is good for teams that already use Node.js or Python but need to span the divide between technical and nontechnical people.

If you want a cloud-based option, check out Replit. The service lets developers build, share and deploy software quickly without having to set up extra tools. Replit offers a full-featured environment for building internal tools, data pipelines and more, with support for multiple programming languages. It comes with collaboration tools, AI code generation and deployment options, so it's good for solo developers and teams. The service also has security features like endpoint security and fine-grained permissions.

Last, Pipedream is worth a look. It lets developers build complex apps by hooking into more than 2,100 APIs with npm and PyPI packages. Pipedream can deploy apps without requiring server management and lets you add custom logic with languages like Python and Node.js. It offers instant deployment and a range of prebuilt components, making it a good tool for gluing different services together and building complex apps.
