Lovable vs MySpec

Lovable

The cleanest prompt-to-app experience for someone who cannot write React, and GitHub sync means you are not locked in — but 100 credits a month is less runway than it sounds once the app gets real.

Pros

• +Live preview after each change keeps iteration legible to non-developers
• +GitHub sync and Supabase mean the output is real, portable code
• +The free tier is enough to find out whether the idea works
• +Per-action credit costs are published, so estimating is possible

Cons

• −Free tier caps at 30 credits a month regardless of the daily grant
• −Debugging a bad generation can cost more credits than the original build
• −Opinionated stack — React front end, Supabase back end, little room to differ
• −API access is reserved for the Business tier, which charges double Pro's price per credit

MySpec

Spec-driven development is the current answer to agents that build the wrong thing confidently, and MySpec is a clean implementation of it: a real interview, four files with distinct jobs, and testable EARS+ requirements instead of prose. The MCP server matters — the spec lands where the agent already works. It is an unlimited free beta right now, which also means the pricing you eventually pay is unknown.

Pros

• +Four distinct output files rather than one blob, each with a defined job
• +Requirements use the testable EARS+ when/if/then format instead of prose
• +Brownfield mode reads an existing codebase and scopes the change rather than restating the whole system
• +MCP server connects it to Claude Code, Cursor and Claude Desktop
• +Live Mermaid rendering for flowcharts, ER and sequence diagrams

Cons

• −Open beta, so nothing about stability, support or eventual price is settled
• −No company name, country or team disclosed anywhere on the site
• −The interview adds real time before any code gets written
• −Announced Pro and Team tiers have no published figures
