Where Softgen is different

  • Predictable credits instead of raw tokens: a Softgen credit maps to AI work done, so pricing is easier to reason about than counting millions of tokens
  • Managed Supabase included on paid plans, with auth, database, and storage set up by the agent
  • Model choice per task: GPT-5.1 or Gemini 3.1 Pro on Starter and 12+ models on Pro, instead of a fixed model

Where Bolt.new is strong

  • Very fast in-browser previews via WebContainers
  • Unused tokens roll over on the Pro plan
  • Free tier with a daily token allowance
