Understand Lovable's managed backend and unified credits alongside Bolt Cloud, token allowances and code workflows; compare Uvilno's separate source entitlement.
Consider Uvilno for a narrowly defined web application whose source entitlement should remain separate from recurring generation. The visible remaining-usage meter, saved versions and free mapped visual changes can make iteration easier to account for. A $4.99 unlock is a permanent source handoff for one project, not a substitute for a generation or infrastructure budget.
Check current Uvilno pricing and the supported SDK contract.
Uvilno provides conversation-led frontend generation, schema-declared app data and a $4.99 permanent source unlock for one project. Plus costs $10/month; Pro costs $20/month with unlimited source unlocks during the subscription. Generation and hosted services have separate limits.
The five criteria below allocate 100 possible points. Available documentation and recorded Uvilno checks establish some conditions; they do not establish equivalent performance across products. Overall scores remain unmeasured. Unknown evidence is not treated as a failed capability.

Each listed condition has a five-point allocation. This page records evidence, not awarded performance points. “Documented” identifies a stated capability with its requirements. “Recorded Uvilno check” identifies a named first-party fixture; it is not independent comparative testing. “Unmeasured” leaves the condition open. Source-access purchases, annual subscriptions and operating services are different costs.
Build the same app, obtain its complete source, record the actual purchase, and rebuild on a separate host. Test continued source access and document the backend services that still need migration.
Create, edit and remove the same records; reload; repeat with another account; check record permissions; run a real app-AI request and inspect a triggered automation. Record each managed or external dependency.
Apply the same specified changes to matched projects. Compare exact file deltas, verify the rendered target and unchanged routes, and record end-to-end timings including verification. Publish failures as well as successes.
Make the same direct edit and introduce the same reproducible fault. Inspect actual usage ledgers, repair limits and saved-version behavior. A limited free path must not be described as unlimited free coding.
Build and navigate the same route plan, exercise state across pages, then measure frame time and input response on named devices. Framework support or an attractive screenshot does not establish a universal 60 FPS result.
A published 4–8 second edit claim needs timing data. A 60 FPS claim needs a named workload, device and frame-time record. Neither is inferred from feature availability, code export or a screenshot. The recorded checks and open evaluation protocol describe the current measurement boundary.
Lovable and Bolt.new both provide app-building workflows with managed backend options. Lovable documents a shared credit balance for building and app operation; Bolt advertises token allowances and Bolt Cloud hosting and databases. A useful comparison follows the cost and responsibility for the same deployed workflow, rather than assuming that one product needs manual backend wiring or that the other's subscription covers every operating expense.
Official product references: Lovable documentation · Bolt.new documentation.
Lovable Cloud includes managed database, authentication and storage. Bolt Cloud also includes database and user-management facilities. A universal claim that either product can only work after manually connecting Supabase would misdescribe the current offer. Compare schema editing, permission review, backup and recovery behavior for the particular backend you choose.

Lovable Pro 100 and Bolt Pro both list a $25 monthly entry in the reviewed sources, but their included units and operating policies differ. Lovable uses credits; Bolt's entry Pro offer lists a token allowance. Do not equate one credit with a fixed number of tokens or forecast project cost from subscription price alone.

Ask for one navigation change after a working build. Compare the changed files, check that existing form behavior survives, and reopen the saved version. Then repeat a database-backed interaction. These observations reveal the workflow cost for your app without presenting an undocumented edit-speed or error-repair ranking as a fact.

| Capability | Uvilno | Lovable | Bolt.new |
|---|---|---|---|
| Primary job | Conversation-led websites and data-backed frontend apps, isolated preview and source handoff. | AI builder for websites and full-stack web apps. Source | Browser-based AI website and application development. Source |
| Paid entry plan | Plus $10/month; individual source unlock $4.99 once per project. | Pro 100: $25 monthly or $250 annually upfront. Source | Entry Pro $25/month, billed monthly. Source |
| Code export | Unlocked ZIP includes source, project images, bundled fonts and licenses. | Export source and move hosting; services require separate migration. Source | Download a project or use GitHub for source handoff. Source |
| Hosting | Publish Studio serves an explicitly published version; exported source can also run on another host. Service limits apply. | Managed Lovable hosting or your own infrastructure. Source | Website hosting is included, with plan-dependent capacity. Source |
| Custom domains | Verified custom domains are available for entitled projects through Publish Studio; external hosting has its own DNS workflow. | Custom-domain workflow is documented; plan and DNS requirements apply. Source | Custom domains and branding removal on paid plans. Source |
| Database and backend | Typed Uvilno.db collections, persistent CRUD and App Data; hosted services remain a dependency after export. | Built-in Cloud backend with database, storage and compute billing. Source | Bolt Cloud databases and supported external providers. Source |
| Visitor authentication | Project-scoped managed visitor identities when enabled; not a portable identity database by ZIP alone. | App authentication is part of the backend configuration. Source | Authentication integrations are part of the app-building workflow. Source |
| In-app AI | Uvilno.ai.ask/json runs real owner-funded inference; 600-token replies and admission limits apply. | Managed app AI connector provides real model calls and workspace usage billing. Source | AI integrations can be implemented in the project; this review did not measure an app-AI proxy. Source |
| Database automations | Bounded create/update/remove rules and notifications commit atomically; inspect Automations & Logs. | Backend functions and scheduled jobs are documented; execution differs from Uvilno's bounded atomic rules. Source | Server functions and connected services can implement workflows; no atomic-rule equivalence is claimed. Source |
| Focused edit context | @file, @page, @db and inspected-element references guide bounded source retrieval with a repo map. | Chat, generated modules and repository sync; no same-brief timing benchmark was run. Source | Code view, prompting and GitHub version control; no fixed edit latency established. Source |
| Repair and interaction cost | Mapped visual edits cost 0% usage. Limited reproduced static-runtime repairs are platform-funded; ordinary AI edits are metered. | Build/chat and app runtime use the documented credit balance; check action-specific charges. Source | Reading and modifying project files consumes model tokens under its usage model. Source |

Read the linked vendor sources for quotas and eligibility. Uvilno’s column follows its plan configuration and public SDK documentation. A subscription, a source license and a hosted application budget are different commitments.
Give each shortlisted platform the same brief, content and acceptance criteria. Keep the first working result, recorded usage and remaining manual work together.
No. Bolt documents Bolt Cloud hosting and databases, including authentication and server-function tools. Check the chosen runtime and service limits for the application rather than treating the product as frontend-only.
No. Lovable credits and Bolt tokens represent different accounting models. The reviewed monthly entry prices are comparable subscription figures, not proof of equivalent build capacity or running cost.
Uvilno's $4.99 unlock covers one project's source entitlement. It does not purchase unlimited model usage, database capacity or another provider's infrastructure. Compare those needs separately.
Uvilno publishes this comparison and is displayed first as an editorial presentation choice, not an independent ranking. Vendor statements come from the linked official documentation reviewed on October 28, 2026. No common-brief generation contest, aesthetic score, universal frame rate or edit-latency benchmark was performed for this page. A source handoff and migration of hosted data, accounts and services are separate tasks.
A product comparison can narrow the options. Your own content, constraints and review decide the fit.
The brief is preloaded for you to review. AI generation starts only when you send it. Included usage is limited; source access requires unlock.
