HappySeeds (https://happyseeds.ai) generates web applications from an instruction.

The interface offers a 3-step flow: production plan of the application (with possible start/context documents), code generation and then upload to Happyseeds servers.

3 language models to choose from: Claude Sonnet 4.5, Claude Opus 4.6 and GPT-5.4.
Access to the whole of the team.

English but French interface supported in the instructions.

Note: the generations can be long, compensated by a strong anchoring in education which allows generations to be generated almost in one go.

100 free monthly credits (Multiplication Farm: 5 credits consumed).
