A Lovable alternative that generates approvals and permissions, consistently
Lovable generates full-stack React/TypeScript with AI and lets you take the code via two-way GitHub sync (its back end/DB is Supabase). d-bye has the AI draft a validated spec instead of raw code, passes type checks and a compile check, lets you choose your backend language, and models foreign keys, approval flows, and role-based permissions in the spec.
Where Lovable starts to feel limiting
The model emits raw code
Lovable generates code directly from a prompt. Quality is high, but nothing programmatically guarantees it type-checks, compiles, or stays consistent across the stack — the larger the app, the more that is your job.
Back end / DB is Supabase-based
Lovable auto-provisions Supabase (PostgreSQL, auth, storage). Fast, but your back-end stack and architecture choices center on Supabase.
Credit-based (token) pricing
Free ($0, 5 daily credits) / Pro $25 (100 monthly credits) / Business $50 / Enterprise. You spend credits as you generate.
How d-bye differs — a validated spec, stack choice, and business depth
d-bye treats the design spec as the single source of truth: design screens, DB, flows, and permissions, then generate a full stack. The AI drafts the spec, not raw code, then passes validation and generation gates.
- ✓The AI drafts a spec, not raw code → type checks and a compile check catch structural errors before export.
- ✓Choose your backend (multi-language, not Supabase-only). Generates a database schema (DDL). See supported languages & databases
- ✓Front end, back end, and DDL derive from one spec, so they stay consistent across the stack.
- ✓Foreign keys, approval flows, and role-based permissions are modeled in the spec.
- ✓Export everything as a ZIP (like Lovable, the code is yours — plus you keep the spec as an asset).
Where Lovable generates React/Supabase with AI, d-bye generates a business app — approvals and permissions included — from a validated spec, consistent across the stack.
Comparison
| Lovable | d-bye | |
|---|---|---|
| Generation starts from | The model emits raw code | A validated spec, then code |
| Quality gate | — (model output) | Type checks + compile check every generation |
| Back end / DB | Supabase-based (Postgres/auth/storage) | Backend (multi-language) + database schema (DDL) See supported languages & databases |
| Business features (FK, approvals, roles) | Build by hand | Modeled in the spec and generated |
| Code ownership / export | Yes (two-way GitHub sync) | Yes (full export as a ZIP + the spec) |
| Pricing | Credit-based (Free / $25 / $50) | Sandbox ¥0 / Personal ¥2,980+ (full export) |

Which should you choose? (an honest split)
Lovable fits when: you want to spin up a full-stack React + Supabase app fastest; you iterate prompt-first; the Supabase setup works for you.
d-bye fits when: you want to choose your backend language; you need approvals and permissions generated consistently; you want AI output constrained by type and compile checks.
If unsure, try the free Sandbox first: open a template as a working preview and check the generated code (front end, back end, DDL).
FAQ
- Can Lovable export code? How is d-bye different?
- Yes — Lovable lets you take the code via two-way GitHub sync. d-bye also exports everything as a ZIP. The difference is method and stack: Lovable emits raw code and is Supabase-based, while d-bye generates the backend (multi-language) + database schema (DDL) from a validated spec, consistently across the stack.
- Can I choose the back-end architecture?
- d-bye lets you switch the back end between multiple languages and generates the database schema (DDL). Lovable auto-provisions Supabase.
- Which is better for business apps with approvals and permissions?
- d-bye models foreign keys, approval flows, and role-based permissions in the spec and generates them. For the consistency of a long-lived business app, d-bye fits; for fast spin-up, Lovable is strong.
- Will the AI-generated code break?
- d-bye has the AI draft a spec rather than raw code, then runs type checks and a compile check as a gate. See the Learn guide “an AI code generator that actually works”.
