Compare Uvilno and Bolt.new across 24 practical criteria: app data, source handoff, token usage, hosting, integrations and annual budget assumptions.
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.
Key takeaway, October 2026. Uvilno combines typed hosted data, app AI and bounded transactional automations with a permanent $4.99 source unlock. Choose it when that frontend-and-managed-services contract fits your app; compare Bolt.new's runtime, service limits and handoff against the same requirements.
Where Bolt.new fits. Choose Bolt when you want an in-browser development environment, app services and a hosted publishing path alongside AI editing.
Where Uvilno fits. Choose Uvilno for a compact chat-and-preview workflow, declared app collections, transactional data rules and an individual permanent source unlock.
Bolt bundles a broader development and hosting workflow. Uvilno's source purchase makes the handoff explicit, with production hosting chosen separately.
Feature summaries reflect the linked documentation. “Requires configuration” is a responsibility to plan for, not a claim that the other product cannot do it.
| What to compare | Uvilno | Bolt.new |
|---|---|---|
| Primary job | Conversation-led websites and data-backed frontend apps, isolated preview and source handoff. | Browser-based AI website and application development. [2] |
| Paid entry plan | Plus $10/month; individual source unlock $4.99 once per project. | Entry Pro $25/month, billed monthly. [1] |
| Free starting point | $0 plan with limited included AI usage; source stays locked until entitled. | Free includes 1M monthly tokens with a 300K daily limit. [1] |
| Source access | Inspection and raw source require a permanent project unlock. | Code view and a downloadable project are documented. [4] |
| Code export | Unlocked ZIP includes source, project images, bundled fonts and licenses. | Download a project or use GitHub for source handoff. [3] |
| Technical foundation | HTML/CSS/JavaScript; eligible projects use a Next.js static-export workflow. | Web development environment with supported frameworks and packages. [2] |
| Design workflow | Describe the audience and brand; add images and visual references. | Prompting, image references and visual edits. [2] |
| Refinement | Chat edits, saved versions and mapped Inspect & Edit controls. | Plan Mode, Code view, follow-up prompts and restoration. [2] |
| Preview and review | Interactive preview runs on a separate origin; review desktop and phone layouts. | In-browser preview controls and project review. [2] |
| 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. [1] |
| 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. [1] |
| 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. [1] |
| 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. [2] |
| Payments | Stripe test Checkout connector; live use depends on configuration and release availability. | Stripe integration is documented; configure your account. [2] |
| Existing code and Git | GitHub import, push and pull for supported frontends; source pushes require unlock. | GitHub import, sync and branch workflows. [3] |
| 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. [1] |
| Usage limits | Finite AI usage on every plan. Unlimited source unlocks are not unlimited generation. | Tokens are limited; large context and changes affect consumption. [1] |
| 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. [3] |
| 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. [5] |
| 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. [2] |
| 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. [5] |
| 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. [5] |
| 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. [3] |
| 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. [6] |

Uvilno source: plans and source entitlement, with implementation boundaries described on this page. Always review the actual exported project and configured services.
Uvilno's October 27 integration run exercised real hosted services with a code-authored fixture. It was not an independently scored CRM-generation contest or a test of Bolt.new. We publish the boundary so a passing SDK check cannot be mistaken for a universal build-completion rate.
| Check | Uvilno: observed result | Bolt.new |
|---|---|---|
| Saved data | A task was persisted through the actual SDK and recovered after an iframe reload. | Not measured in this run. Official capability documentation is linked separately. |
| Database effects | Task creation wrote an activity record and notification in the same transaction. | Not measured in this run. Official capability documentation is linked separately. |
| Account boundaries | Guest/Member/Admin view changes preserved the real visitor and creator identities. | Not measured in this run. Official capability documentation is linked separately. |
| Targeted recovery | A reproduced static ReferenceError was repaired in app.js and browser-checked without a customer usage-ledger entry. | Not measured in this run. Official capability documentation is linked separately. |

Real free-model text and JSON app inference also passed locally; the production replay verified persistence, automations and isolation without additional inference. No cross-vendor latency, aesthetic score, completion percentage or total operating cost was measured. Read the machine-readable evidence and methodology.
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.
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.
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.
Published plan prices are a starting point. Add the costs your actual website needs; this is a budget worksheet, not a price quote or a measured savings claim.
Zero in an optional field means that cost is excluded from this worksheet. It does not mean unlimited or free generation, provider usage, hosting or domains. Taxes, currency conversion and labor are excluded.
Source unlocks persist. This worksheet models new projects at an even monthly pace; Plus's two included unlocks must be used in their paid month. Existing unlocked sites do not require another unlock.
Configured monthly AI capacity: Pro is 2.5× Plus; Ultra is 5× Pro. These are usage-capacity ratios, not a guaranteed number of builds.
Entry Pro is $25 billed monthly. No unverified annual discount is applied. Entry Pro includes 10 million monthly tokens. Model work, hosting limits and any external services still need capacity planning. Pricing checked 2026-10-27. See the official pricing source.
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.
No. Entry Pro lists 10 million monthly tokens. No daily token limit on a paid plan does not remove its monthly allowance.
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.
Publish Studio can serve an explicitly published version, and entitled projects can connect a verified custom domain. Every plan still has finite AI usage and service limits. A permanent source unlock grants source access, not unlimited hosting or generation. External hosting and managed-service migration need separate planning; payments currently use test workflows.
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.
