ManyChat could offer developer accounts specifically for professionals who need to create and test flows. These accounts would be free and include full operational functionality, but limited to a staging environment.
This means developers could build and thoroughly test flows — including integrations — without being able to deploy them in real-world scenarios. To use these flows in production, the developer would simply export them into a paid (PRO or higher) account.
This feature would make it much easier to present and sell projects to clients, since developers could maintain a library of reusable templates ready to be implemented.
