Compare Base44 and Lovable backend models, source and data exports, visitor accounts and migration work, with Uvilno's $4.99 source option alongside.
Uvilno offers a third route for an app that fits typed schema collections and the supported SDK: build by chat, review the isolated preview and unlock source permanently for $4.99. Its exported frontend can still depend on Uvilno-managed auth and data. Apply the same migration checklist to Uvilno rather than calling every export a fully independent backend.
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.
Base44 and Lovable both document managed app backends, so the choice is more specific than database versus no database. Compare their data model, visitor authorization, operating allowances and export workflow. Base44's CLI eject command copies frontend and backend resources into a separate project but does not copy application data. Lovable also treats code and database exports as separate responsibilities.

Base44's documented core features include database functionality and authentication; Lovable supplies a managed backend too. Define the entities, relationships and allowed operations before choosing. A convincing demonstration should save real records and deny an unauthorized write, not simply display an editable table in the preview.
Base44's eject workflow produces a separate local project and a new app identity. Its copied schema starts with an empty database. Lovable's database export is also separate from Git-synchronized code. Record whether files, secrets, functions, user identities and existing rows need additional work; do not describe either platform as universally unable to export source.
Choose a realistic number of active visitors, form submissions and AI requests, then inspect each vendor's current plan and usage policy. A plan's message or integration allowance is not a guaranteed number of complete applications. Preserve the billing interval and quote when estimating a move, and include the work of recreating hosted-service behavior.

| Capability | Uvilno | Base44 | Lovable |
|---|---|---|---|
| Primary job | Conversation-led websites and data-backed frontend apps, isolated preview and source handoff. | Integrated AI app building, hosted backend and data management. Source | AI builder for websites and full-stack web apps. Source |
| Paid entry plan | Plus $10/month; individual source unlock $4.99 once per project. | Starter $192/year; GitHub-listed Builder $480/year, annual billing. Source | Pro 100: $25 monthly or $250 annually upfront. Source |
| Code export | Unlocked ZIP includes source, project images, bundled fonts and licenses. | Advertises ownership and two-way GitHub source export; plan conditions apply. Source | Export source and move hosting; services require separate migration. Source |
| Hosting | Publish Studio serves an explicitly published version; exported source can also run on another host. Service limits apply. | Apps use Base44 hosting and backend infrastructure. Source | Managed Lovable hosting or your own infrastructure. Source |
| Custom domains | Verified custom domains are available for entitled projects through Publish Studio; external hosting has its own DNS workflow. | Paid plans list domain connection; check exact plan and DNS setup. Source | Custom-domain workflow is documented; plan and DNS requirements apply. Source |
| Database and backend | Typed Uvilno.db collections, persistent CRUD and App Data; hosted services remain a dependency after export. | Built-in entities, records and a data dashboard; test and production data controls. Source | Built-in Cloud backend with database, storage and compute billing. Source |
| Visitor authentication | Project-scoped managed visitor identities when enabled; not a portable identity database by ZIP alone. | App sign-in and role/access settings; data permissions require review. Source | App authentication is part of the backend configuration. Source |
| In-app AI | Uvilno.ai.ask/json runs real owner-funded inference; 600-token replies and admission limits apply. | invokeLLM and app agents use supported managed model presets. Source | Managed app AI connector provides real model calls and workspace usage billing. Source |
| Database automations | Bounded create/update/remove rules and notifications commit atomically; inspect Automations & Logs. | Scheduled, data-event and connector triggers; workflows are replacing automations. Source | Backend functions and scheduled jobs are documented; execution differs from Uvilno's bounded atomic rules. Source |
| Focused edit context | @file, @page, @db and inspected-element references guide bounded source retrieval with a repo map. | Base Code edits connected repositories with branch previews and commit history. Source | Chat, generated modules and repository sync; no same-brief timing benchmark was run. Source |
| Repair and interaction cost | Mapped visual edits cost 0% usage. Limited reproduced static-runtime repairs are platform-funded; ordinary AI edits are metered. | Building and live integration work use distinct message/integration credit allowances. Source | Build/chat and app runtime use the documented credit balance; check action-specific charges. 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.
That blanket claim is inaccurate. Base44 documents a CLI eject workflow that downloads frontend code, entity schemas and backend resources into a separate project. Its documentation says the ejected database is empty; data migration is separate.
Yes. Both document database and authentication capabilities. Their exact schema tools, permission controls, billing and portability behavior should be checked against the same application requirements.
Do not assume so. Source, application data, uploaded files, secrets and identity services have distinct migration requirements. Prove each part with a disposable test before moving a real application.
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.
