# Base44 alternatives

Canonical: https://uvilno.com/alternatives/base44
Updated: 2026-10-28

Published by Uvilno. Uvilno is presented first as the publisher's editorial order, not an independent rank. Documentation, recorded first-party checks and unmeasured outcomes are distinct. Overall quality scores remain unmeasured. Prices and vendor capabilities can change; source access and operating services are separate purchases.

Choose Uvilno for a chat-and-preview workflow with declared collections, real app AI, transactional data rules, explicit context mentions and a permanent $4.99 source entitlement per project.

Choose Base44 when an integrated app platform with its own data dashboard, hosted backend, access controls and scheduled or event-driven workflows suits your operating model.

Both offer source handoff and managed backend services. Exporting files does not itself migrate records, identities, credentials or the hosted services those files call. Compare the actual exit plan, not a claim of universal zero lock-in.

## 2026 full-stack engineering evaluation rubric

Uvilno first because Uvilno publishes this comparison; not a measured rank. The five publisher-selected criteria total 100 points. A documented capability is not an equivalent hands-on result. Unknown checks stay unmeasured, never failed. Overall scores remain null until a comparable test protocol is completed.

- **Code ownership & export cost: 25 possible points.** 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.
- **Database, accounts & app AI: 25 possible points.** 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.
- **Targeted edit precision & speed: 20 possible points.** 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.
- **No-usage editing & recovery: 15 possible points.** 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.
- **Multi-page & interactive applications: 15 possible points.** 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.

### Uvilno

Overall score: not measured. 17 documented or recorded checklist conditions; 3 unmeasured; 0 explicitly unmet. This is evidence coverage, not product quality.

**Code ownership & export cost**
- Documented: An owned, unlocked project can export its runtime-appropriate source and referenced media. Sources: https://uvilno.com/docs.
- Documented: Supported frontends can use authorized GitHub import, push and pull; a source push requires unlock. Sources: https://uvilno.com/docs.
- Documented: Free is $0; a source unlock is $4.99 once. Plus is $10/month, Pro $20/month and Ultra $59/month. Generation and hosted services are separate. Sources: https://uvilno.com/pricing.
- Documented: The $4.99 purchase permanently unlocks one project's source; subscription generation remains finite. Sources: https://uvilno.com/pricing.
- Documented: Source export is not a copy of managed records, visitor identities, payment credentials or hosted services. Sources: https://uvilno.com/docs.

**Database, accounts & app AI**
- Documented: Uvilno.db CRUD and App Data use schema-declared, persistent app records. Sources: https://uvilno.com/benchmarks.
- Documented: Managed visitor identities are isolated per project from the creator's platform session. Sources: https://uvilno.com/benchmarks.
- Documented: Uvilno.ai.ask/json makes real owner-funded calls; admission limits and a 600-output-token ceiling apply. Sources: https://uvilno.com/benchmarks.
- Documented: data/schema.json declares collection fields and access; the runtime exposes validated data operations. Sources: https://uvilno.com/docs.
- Documented: Bounded record effects and notifications execute in the triggering record transaction; arbitrary server code, email and network actions are outside this rules engine. Sources: https://uvilno.com/benchmarks.

**Targeted edit precision & speed**
- Documented: @file, @page, @db and bounded repository retrieval supply explicit context. Sources: https://uvilno.com/docs.
- Documented: The mapped inspector supplies selected-element context or a supported direct text, link or color change. Sources: https://uvilno.com/docs.
- Unmeasured: Recorded targeted checks do not establish a comparative edit-accuracy rate across vendors.
- Unmeasured: No matched cross-vendor timing establishes a universal 4–8 second edit duration.

**No-usage editing & recovery**
- Documented: Mapped direct text, link and color changes use 0% model usage; unsupported computed elements use the normal scoped-edit path. Sources: https://uvilno.com/docs.
- Documented: A reproduced native-static runtime fault was repaired and rechecked without customer usage. This bounded path is rate-limited and does not cover every engine error. Sources: https://uvilno.com/benchmarks.
- Documented: Saved-version and entitled per-file restores preserve checkpoints without invoking the generation model; verification still applies. Sources: https://uvilno.com/docs.

**Multi-page & interactive applications**
- Documented: Contract-first route plans and reusable modules support multi-page frontends; saved legacy and eligible Next.js projects retain their respective runtimes. Sources: https://uvilno.com/docs.
- Documented: The portable Canvas game runtime and authored interactive fixtures provide workload evidence, not a promise about every generated game. Sources: https://uvilno.com/benchmarks.
- Unmeasured: A matched hardware/workload frame-time study has not been published; 60 FPS is not guaranteed.

### Base44

Overall score: not measured. 9 documented or recorded checklist conditions; 11 unmeasured; 0 explicitly unmet. This is evidence coverage, not product quality.

**Code ownership & export cost**
- Documented: Advertises ownership and two-way GitHub source export; plan conditions apply. Sources: https://base44.com/pricing.
- Documented: GitHub integration on Builder and above; Base Code edits connected repositories. Sources: https://docs.base44.com/Getting-Started/base-code.
- Unmeasured: Starter is displayed at $16/month billed annually ($192 upfront). Builder, which lists GitHub integration, is $40/month billed annually ($480 upfront). An equivalent complete source-access purchase has not been priced by a matched export test.
- Unmeasured: This specific source-access condition has not been established here; it is not marked unsupported.
- Documented: Source ownership is documented; migrate backend data and connected services separately. Sources: https://docs.base44.com/Getting-Started/base-code.

**Database, accounts & app AI**
- Documented: Built-in entities, records and a data dashboard; test and production data controls. Sources: https://docs.base44.com/Building-your-app/Managing-your-app-data.
- Documented: App sign-in and role/access settings; data permissions require review. Sources: https://docs.base44.com/Setting-up-your-app/Managing-access.
- Documented: invokeLLM and app agents use supported managed model presets. Sources: https://docs.base44.com/developers/backend/resources/models.
- Documented: Typed entities and visual record management are part of the built-in backend. Sources: https://docs.base44.com/Building-your-app/Managing-your-app-data.
- Documented: Scheduled, data-event and connector triggers; workflows are replacing automations. Sources: https://docs.base44.com/Building-your-app/Creating-automations.

**Targeted edit precision & speed**
- Unmeasured: Exact context-selection behavior needs a documented or observed matched test; repository access alone does not prove surgical precision.
- Unmeasured: Equivalent selected-element context has not been checked here.
- Unmeasured: No equivalent before/after edit-accuracy benchmark is recorded here.
- Unmeasured: No comparable end-to-end edit-timing distribution is recorded here.

**No-usage editing & recovery**
- Unmeasured: No-usage visual-edit terms have not been established here; absence of a recorded check is not a paid-only claim.
- Unmeasured: The same injected fault and actual customer usage ledger have not been inspected on this product.
- Unmeasured: A matched restore and usage-ledger check has not been run here; existing source-control features are described in the product comparison.

**Multi-page & interactive applications**
- Documented: Integrated AI app building, hosted backend and data management. Sources: https://base44.com/pricing.
- Unmeasured: An equivalent interactive workload has not been run in this evaluation; this does not imply an inability to build games.
- Unmeasured: No matched workload/device frame-time measurement is recorded here.

## Pricing basis

Starter is displayed at $16/month billed annually ($192 upfront). Builder, which lists GitHub integration, is $40/month billed annually ($480 upfront). The captured offer uses annual billing. Monthly checkout, credit consumption, integration quotas and any third-party charges must be checked separately; Starter is not the GitHub-export comparison plan.

### Is Base44 a platform with no code export?

No. Base44 advertises source ownership and two-way GitHub export, with GitHub integration listed on Builder and higher plans. Check the current plan and how its managed backend is configured before choosing a migration path.

### Does Uvilno's $4.99 unlock include a year of hosting and app AI?

No. It permanently unlocks one project's source. Generation remains metered, app AI uses the creator's allowance, and exported managed services still need a running service or replacement. Add hosting and operational costs separately.

### Can I switch Uvilno's preview to Admin to grant permissions?

No. Guest, Member and Admin preview views are presentation tests. The actual isolated visitor identity and server-side record authorization remain unchanged.

### Which Base44 price is used in the annual calculator?

The Starter annual offer is $192 upfront. Builder is separately displayed at $480 annually and lists GitHub integration. The calculator models the named plan, not the cheapest route to every feature, and excludes hosting overages and third-party services unless you enter them.
