Bolt.new - Pros & Cons

Pros

  • ✓Zero local setup — everything runs in the browser via WebContainer
  • ✓Auto-routes between Claude, GPT, and Gemini for best-fit model per task
  • ✓One-click Netlify deploy plus GitHub sync keeps output real, not throwaway
  • ✓First-class Supabase and Firebase wiring for auth and database in minutes
  • ✓Mobile apps let you build and edit from an iPhone or Android

Cons

  • ✗Credit-based pricing burns fast on large projects and error-heavy iterations
  • ✗Only supports web/Node stacks — no native iOS, Android, or Python backends
  • ✗No MCP server integration; extending with custom tools requires code
  • ✗Generated code quality can drift on projects over a few thousand LOC

Flowise - Pros & Cons

Pros

  • ✓Truly open source; self-host gives you full control of data and prompts
  • ✓Visual canvas dramatically shortens the prototype-to-demo loop
  • ✓Huge integration surface inherited from LangChain and LlamaIndex
  • ✓MCP client support means new tool ecosystems plug in without code
  • ✓Active community: 30k+ GitHub stars, frequent releases, Discord support

Cons

  • ✗Visual graphs get unwieldy at scale; complex flows can become hard to maintain
  • ✗Some breaking changes between versions; pin and test before upgrading
  • ✗Observability and evals are basic compared to dedicated platforms
  • ✗Production deployment (auth, rate limiting, monitoring) is on you for self-host
  • ✗Cloud pricing is competitive but execution limits can bite for chatty agents
