What Dvl'epr is

Dvl'epr removes the server-side overhead from building business applications

You define what your application does — screens, data, workflows, roles — and the platform generates how it works.

Define
Generate
Deploy
No boilerplate No framework setup No component library decisions No DevOps No backend code

Just declarative definitions, HTML, SQL, and JavaScript.

Why it's faster

65–75% faster than traditional frameworks

Prototypes in days. Production apps in weeks. Authentication, sessions, RBAC, AJAX, DOM injection, form handling, validation, and security — all generated automatically.

Speed
Intelligence
AI accelerates everything
Dvl'epr apps are HTML and SQL — the two languages AI models generate most accurately.

Provide your app spec, UI rules, and SKILL.md, and AI produces complete screens in minutes.

✓ Works with Claude, GPT-4, Gemini, Cursor
✓ 15+ Bizheart production apps built with AI
✓ Days per app with AI, weeks without
How it works

From brief to application in days

01
Client describes what they need
Screens, data, workflows, roles — a conversation, not a 40-page spec.
02
Build manually or with AI
Declarative XML for structure. SQL for data. JS for UI behaviour.
03
Review, refine, deploy
Every change renders instantly. No build steps. No config.
04
Go live on Dvl'epr infrastructure
Hosting included. No Vercel. No environment variables.
Shallow learning curve
The only new skill is the declarative format
HTML CSS JavaScript / jQuery SQL

Declarative XML is the only new concept — most developers are productive within a day or two.

Platform capabilities

The server-side work is already done

Server-Side Generated
Authentication, sessions, data retrieval, form processing, validation, and security — handled automatically.
AJAX & DOM — Automatic
Dynamic updates, modal forms, live data — no AJAX functions to write or maintain.
Any CSS Framework, Any JS Library
Bootstrap, Tailwind, your own design system — jQuery is the only dependency.
Auth & RBAC
Role-based access control defined in your application definitions.
Extensible via Plugins
Extend server-side logic with PHP plugins — third-party APIs, calculations, integrations.
Easy to Maintain
Declarative definitions mean any Dvl'epr developer can maintain any project.
REST, As Intended
Stateless, resource-based endpoints over standard HTTP verbs. Client credentials protect every endpoint.
What you can build

If it needs a database, Dvl'epr can build it

Business Applications
CRM, ERP, HR, Accounting, Inventory, Purchasing.
Portals & Self-Service
Customer, supplier, member, patient, B2B ordering, booking systems.
Content & Publishing
Websites, CMS, catalogues, knowledge bases — a faster, more secure alternative to WordPress.
Operational Tools
Order management, project management, field service, helpdesk, compliance, surveys.
Dashboards & Reporting
KPIs, analytics, multi-tenant reporting, data visualisation.
Bespoke SPAs
Write your own frontend. Dvl'epr handles server-side, database, auth, and AJAX.

A note for vibe coders

Better than Bolt, Lovable, or v0 — and cheaper on tokens

React-based vibe tools burn thousands of tokens per feature. Dvl'epr doesn't have that wall.

React (Bolt/Lovable/v0)~300+ tokens per screen
Dvl'epr~50 tokens per screen
Build faster. Spend less. Ship something that lasts.
