Compare Uvilno and Emergent for database-backed apps, isolated accounts, multi-file editing, source ownership and separately budgeted deployment.
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 Emergent's runtime, service limits and handoff against the same requirements.
Where Emergent fits. Choose Emergent when a full-stack web or mobile application, backend logic and an agent-driven deployment workflow are central to the brief.
Where Uvilno fits. Choose Uvilno for conversation-led frontend apps with typed hosted collections, managed app AI, transactional automations and an individual permanent source unlock.
A broader app platform can remove infrastructure setup, but its runtime and deployment costs belong in the budget. A source handoff still leaves hosting and service configuration to you.
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 | Emergent |
|---|---|---|
| Primary job | Conversation-led websites and data-backed frontend apps, isolated preview and source handoff. | Agent-led full-stack web and mobile app building. [4] |
| Paid entry plan | Plus $10/month; individual source unlock $4.99 once per project. | Standard displays $20/month equivalent billed annually; monthly checkout is unverified here. [1] |
| Free starting point | $0 plan with limited included AI usage; source stays locked until entitled. | Free tier exists; official free-credit descriptions differ. [5] |
| Source access | Inspection and raw source require a permanent project unlock. | Code view; GitHub save on Standard and above. [3] |
| Code export | Unlocked ZIP includes source, project images, bundled fonts and licenses. | Save source through GitHub; copy individual files in Code view. [3] |
| Technical foundation | HTML/CSS/JavaScript; eligible projects use a Next.js static-export workflow. | Full-stack projects with backend and infrastructure support. [4] |
| Design workflow | Describe the audience and brand; add images and visual references. | Prompt-driven app creation and iterative requirements. [4] |
| Refinement | Chat edits, saved versions and mapped Inspect & Edit controls. | Agent changes and follow-up prompts. [4] |
| Preview and review | Interactive preview runs on a separate origin; review desktop and phone layouts. | Build and review an application before deployment. [4] |
| Hosting | Publish Studio serves an explicitly published version; exported source can also run on another host. Service limits apply. | Managed deployment uses a separate credit allowance. [2] |
| Custom domains | Verified custom domains are available for entitled projects through Publish Studio; external hosting has its own DNS workflow. | Custom-domain deployment is documented; check deployment charges. [2] |
| Database and backend | Typed Uvilno.db collections, persistent CRUD and App Data; hosted services remain a dependency after export. | Backend and database workflows are part of the app platform. [4] |
| Visitor authentication | Project-scoped managed visitor identities when enabled; not a portable identity database by ZIP alone. | Generated app login requires configuration and testing. [4] |
| Payments | Stripe test Checkout connector; live use depends on configuration and release availability. | App integrations require the relevant provider setup. [4] |
| Existing code and Git | GitHub import, push and pull for supported frontends; source pushes require unlock. | GitHub source handoff on Standard and above. [3] |
| SEO workflow | Generated page metadata and structure need review; rankings and traffic are not guaranteed. | Review generated content, routes and metadata before launch. [4] |
| Usage limits | Finite AI usage on every plan. Unlimited source unlocks are not unlimited generation. | Standard includes 100 credits; additional credits can be purchased. [1] |
| Moving away | Static source can move to your host; managed auth, data, forms and payments may need migration. | Exported code excludes secrets and application data; migrate those separately. [3] |
| Declarative data and studio | data/schema.json declares typed collections; App Data manages actual owned and shared records. | Database Viewer and generated backend; export records separately from code. [3] |
| In-app AI | Uvilno.ai.ask/json runs real owner-funded inference; 600-token replies and admission limits apply. | One-click LLM integration is listed; app configuration and usage still apply. [1] |
| Database automations | Bounded create/update/remove rules and notifications commit atomically; inspect Automations & Logs. | Custom backend logic can be generated; an equivalent atomic rule contract was not measured here. [4] |
| Role views and authorization | Guest/Member/Admin previews change presentation only; real visitor permissions remain server-enforced. | Emergent Auth supports visitor accounts; generated authorization needs testing. [4] |
| Focused edit context | @file, @page, @db and inspected-element references guide bounded source retrieval with a repo map. | Agent chat and Code view provide project editing; no edit-time benchmark was run. [4] |
| Repair and interaction cost | Mapped visual edits cost 0% usage. Limited reproduced static-runtime repairs are platform-funded; ordinary AI edits are metered. | Testing, debugging and troubleshooting consume credits in the published credit 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 Emergent. We publish the boundary so a passing SDK check cannot be mistaken for a universal build-completion rate.
| Check | Uvilno: observed result | Emergent |
|---|---|---|
| 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.
Both products can support an app with accounts and saved data. Uvilno supplies validated collection schemas, hosted CRUD, declarative automation rules and app AI behind a frontend-oriented generation workflow. Emergent documents a broader generated backend and deployment environment. Compare a complete journey—write a record, reload, sign in as another user, inspect permissions and handle a failed payment—instead of judging only the first preview.
Emergent's documentation describes deployment credit consumption separately from building. That makes a subscription price an incomplete operating budget. In Uvilno, the one-time source unlock also does not buy managed production hosting. For either route, include the expected lifetime of the live site, traffic, domain and external services before comparing annual spending.
Emergent documents source ownership and GitHub handoff, while excluding secrets and data from a source export. Uvilno likewise exports files rather than a complete copy of managed app services. A meaningful portability check includes a local build, environment configuration, asset licenses, data export and a plan for login and payment credentials.
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.
The displayed Standard offer is $20/month equivalent under Annual billing ($240/year). A month-to-month checkout price is not verified here. Deployment and additional credits can add cost. Official pages disagree on the free grant and annual presentation, so neither is assumed here. Pricing checked 2026-10-27. See the official pricing source.
The published Standard entry price is a subscription reference. Deployment and additional credits may add cost; confirm the current checkout and deployment allowance before budgeting.
Yes. Emergent documents GitHub saving on Standard and above, and copying code files on all plans. Secrets and database content require separate handling.
Uvilno is worth evaluating for a website and source handoff. Evaluate Emergent when the site is also an application with backend behavior. Use your own brief and review the resulting flows.
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.
Official vendor documentation checked on 2026-10-27. Billing conflicts and unavailable prices are disclosed above. Uvilno prices follow our current plan configuration; our implementation is the source for its documented boundaries.
