# Uvilno vs Bolt.new

Canonical: https://uvilno.com/compare/uvilno-vs-bolt
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.

## 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.

### Bolt.new

Overall score: not measured. 6 documented or recorded checklist conditions; 14 unmeasured; 0 explicitly unmet. This is evidence coverage, not product quality.

**Code ownership & export cost**
- Documented: Download a project or use GitHub for source handoff. Sources: https://support.bolt.new/integrations/git.
- Documented: GitHub import, sync and branch workflows. Sources: https://support.bolt.new/integrations/git.
- Unmeasured: Entry Pro is $25 billed monthly. No unverified annual discount is applied. 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 can be self-hosted; migrate database and service dependencies too. Sources: https://support.bolt.new/integrations/git.

**Database, accounts & app AI**
- Documented: Bolt Cloud databases and supported external providers. Sources: https://bolt.new/pricing.
- Documented: Authentication integrations are part of the app-building workflow. Sources: https://support.bolt.new/building.
- Unmeasured: App-user inference has not been established in this source set; builder AI alone is not treated as app AI.
- Unmeasured: An equivalent schema-backed SDK contract has not been inspected here.
- Unmeasured: This automation condition has not been established here; supported integrations may provide it.

**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: Browser-based AI website and application development. Sources: https://support.bolt.new/building.
- 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.

| Hosting | Publish Studio serves an explicitly published version; exported source can also run on another host. Service limits apply. | Website hosting is included, with plan-dependent capacity. |
| Custom domains | Verified custom domains are available for entitled projects through Publish Studio; external hosting has its own DNS workflow. | Custom domains and branding removal on paid plans. |
| Database and backend | Typed Uvilno.db collections, persistent CRUD and App Data; hosted services remain a dependency after export. | Bolt Cloud databases and supported external providers. |
| Visitor authentication | Project-scoped managed visitor identities when enabled; not a portable identity database by ZIP alone. | Authentication integrations are part of the app-building workflow. |
| Payments | Stripe test Checkout connector; live use depends on configuration and release availability. | Stripe integration is documented; configure your account. |
| Existing code and Git | GitHub import, push and pull for supported frontends; source pushes require unlock. | GitHub import, sync and branch workflows. |
| SEO workflow | Generated page metadata and structure need review; rankings and traffic are not guaranteed. | Paid plans list SEO boosting; audit the actual published pages. |
| Usage limits | Finite AI usage on every plan. Unlimited source unlocks are not unlimited generation. | Tokens are limited; large context and changes affect consumption. |
| Moving away | Static source can move to your host; managed auth, data, forms and payments may need migration. | Source can be self-hosted; migrate database and service dependencies too. |
| Declarative data and studio | data/schema.json declares typed collections; App Data manages actual owned and shared records. | Bolt Cloud creates databases and provides a data table, logs and user tools. |
| In-app AI | Uvilno.ai.ask/json runs real owner-funded inference; 600-token replies and admission limits apply. | AI integrations can be implemented in the project; this review did not measure an app-AI proxy. |
| Database automations | Bounded create/update/remove rules and notifications commit atomically; inspect Automations & Logs. | Server functions and connected services can implement workflows; no atomic-rule equivalence is claimed. |
| Role views and authorization | Guest/Member/Admin previews change presentation only; real visitor permissions remain server-enforced. | Cloud authentication and user management; verify app-level authorization. |
| Focused edit context | @file, @page, @db and inspected-element references guide bounded source retrieval with a repo map. | Code view, prompting and GitHub version control; no fixed edit latency established. |
| Repair and interaction cost | Mapped visual edits cost 0% usage. Limited reproduced static-runtime repairs are platform-funded; ordinary AI edits are metered. | Reading and modifying project files consumes model tokens under its usage model. |

## Development environment or focused website studio?

Bolt exposes a browser development workflow with code, planning, package support and app integrations. Uvilno keeps the main journey around a conversation and isolated preview, adding source inspection after unlock. The right amount of control depends on who will maintain the result. A developer handoff may benefit from the repository workflow; a small website owner may prioritize reviewing copy and layout.

## A token allowance is not a site count

Bolt's pricing explains that project context affects token use. Ten million tokens cannot be translated into a reliable number of websites without knowing their size and changes. Uvilno's monthly usage is also finite. The calculator below uses published subscription prices and lets you add a budget for extra usage; it does not invent a cost per successful build.

## Included hosting still has boundaries

Bolt includes website hosting and offers custom domains on paid plans, which may be useful when one provider should handle publishing. Uvilno's export workflow leaves production hosting to your choice. Compare bandwidth, database needs, branding, DNS setup and support responsibility before assuming that either route has no additional operating work.

### Can I download my Bolt project?

Yes. Bolt documents a project download and GitHub integration. Confirm that you also have the environment variables, assets and database migration needed to run it elsewhere.

### Does Bolt Pro include unlimited AI generation?

No. Entry Pro lists 10 million monthly tokens. No daily token limit on a paid plan does not remove its monthly allowance.

### Why does the calculator use $25 per month for Bolt?

That is the entry monthly Pro price on the checked pricing page. It is not an estimate of every project's final spend and does not assume a particular annual discount.
