Bonkers by Foyer

Bonkers by Foyer is a creative production system I helped rebuild from v2 to v3, adding reusable templates, multi-model fallback handling, and faster repeat workflows.

Bonkers was built as a general creative production system, not just a one-off image generator. It gives users one place for style discovery, reusable starting points, refinement, and access to past work.

How It Was Built

The main technical choices behind the product, from system design to the parts that make it work day to day.

  • Reworked the generation flow around reusable templates so users start from clearer inputs and better defaults.
  • Added routing across models like Flux, Recraft, and Ideogram, with fallback handling and parallel runs when one model is slow or fails.

Why It Mattered

  • The v3 rebuild made the product easier to use again and again, which helped daily active usage grow by 50%.
  • Fallback handling and parallel runs cut service failures by 60% and improved response times by 30%, so the product felt more dependable.

What Stands Out

  • Turned one-shot generation into a repeatable workflow.
  • Balanced creative range with better reliability across models.
