The team

Team size: 1

I’m Szilard Janko, a full-time React Native developer by day and the solo builder of DCL UI Design Studio (uistudio.app) a drag‑and‑drop designer that exports DCL UIs. My day job keeps me deep in mobile UI and performance. The UI studio project is a similar stack (React, component trees, state, polish) applied to Decentraland tooling. I proposed, shipped, and delivered every milestone on the 2024 Decentraland DAO Platform grant (Decentraland No-Code UI Design Studio) the code is public on github (szilardjanko/ui-design-studio). I’ve also kept the app live in production for over a year post‑grant. This project extends the existing DCL UI Design Studio with new AI features (OpenRouter, BYO key, structured scene patches) plus a focused set of product updates to the current app (undo/redo, shortcuts, .tsx download, more templates, Dropdown, onboarding) all built on the codebase I already ship and maintain.

Skills & expertise:

React, Next.js, Typescript, shipping and maintaining a production web app. React Native with Expo (full time), UI performance, ios and android apps. DCL SDK, UI layouts Data and auth - PostgreSQL with Supabase

Relationship with Decentraland: I have already built in Decentraland

Prior Decentraland work:

Decentraland No-Code UI Design Studio https://uistudio.app/ As well as an in world underwater gallery scene with a shark mini game at Ocean Meta. UI components and an easter egg mini game for Knights of Antrom.

Why build for Decentraland?

I built DCL UI Design Studio in 2024 to help creators ship DCL UIs without hand-written code. Since then, the norm changed, builders and creators now expect AI-assisted drafting and fast iteration, which the first tool doesn’t support. I want to upgrade the project that I already built for DCL. Add AI features + a modern product polish, so DCL’s creators in 2026 get a tool that matches how they work today and the project I built can become more useful again.

The project

What is DCL UI Studio: AI Creation & Chat Editor?

DCL UI Design Studio gets AI: prompt-to-layout on the canvas plus a chat editor for the current selection, with OpenRouter + BYO API key. For Decentraland creators who need HUDs/menus/shops without writing all the @dcl/sdk/react-ecs layout by hand, faster iteration, lower barrier for designers, less boilerplate for devs, same exportable scene UI code as today.

How does this align with the AI-assisted tooling theme?

The proposal adds prompt-to-UI and a selection-scoped chat editor (You select a button, panel, or label on the canvas, open the chat, and ask for changes, the AI only updates that selected piece and its children if it’s a container, so edits stay predictable and easy to undo.) so Decentraland creators generate and refine in-scene UI layouts faster. AI outputs validated structured patches into the studio’s layout model, export stays deterministic. Users connect OpenRouter + their own keys and AI is core to creation and iteration workflow.

Who is this for?

creators, developers, and studios

What problem does this solve?

DCL UI is code-heavy and slow to iterate: non‑coders get stuck, devs burn time on layout boilerplate, and teams can’t prototype HUDs/menus fast enough. This adds prompt-to-layout and “chat edits what you clicked” on top of the existing visual studio so creators reach a shippable first draft and faster polish

Deliverables (90 days)

Within 90 days, I will deliver a working public MVP of an AI-upgraded DCL UI Design Studio web app, live on the existing production site and open sourced in the current repository. The release will include: Natural-language to UI generation: creators can enter a prompt such as “build a shop HUD with an inventory grid and buy button” and generate editable Decentraland UI layouts on the canvas. Conversational AI editing for selected elements: users can refine existing UI by chatting with the editor to change colors, text, spacing, layout, positioning, and existing interaction types like Open Link, Show/Hide, and Count. OpenRouter integration: users connect their own API keys and choose supported models through a single integration, with no platform-managed credit system required. Core workflow upgrades that improve reliability and usability: undo/redo history, keyboard shortcuts, one-click .tsx export of generated DCL UI code, and an interactive onboarding/tutorial flow. Expanded reusable template library: production-ready preset layouts for common Decentraland use cases such as quest HUDs, inventory grids, leaderboards, NPC dialog panels, shop/kiosk UIs, and settings modals. A new Dropdown UI element added to the editor and code generator. Documentation and release materials: updated docs, setup instructions for OpenRouter, example prompts, tutorial content, and a public changelog. Validation/evaluation coverage: a public prompt fixture and test workflow to verify that generated outputs map correctly into the studio’s existing export pipeline. The final output is not a prototype. It is a working, publicly accessible tool upgrade to an already live product, with documentation, reusable templates, and a production ready integration path for Decentraland creators and developers.

Open source

Everything ships in the existing public repo as regular PRs/commits to the same project users already know, with source and docs fully public so anyone can use, fork, learn from, or contribute to the same codebase. GitHub - szilardjanko/ui-design-studio · GitHub

Success metrics

Success would be measured by a mix of product usage, output quality, and ecosystem adoption.

Budget — $15000

The budget is based mainly on the engineering work needed to add AI-assisted UI generation and chat-based editing to an already live Decentraland tool. The main cost drivers are implementing the OpenRouter BYO-key integration, building and testing the structured-output AI workflow, adding supporting UX improvements like undo/redo and new templates, and producing documentation and release materials.

Other funding sources: None

Milestones

Foundation: add the OpenRouter integration, API key settings, structured-output validation, and undo/redo support. AI generation: build natural language to UI generation on the canvas, plus export and workflow improvements. AI editing: add conversational editing for existing UI elements and expand the template library for common Decentraland UI patterns. Polish and release: add the Dropdown element, finish documentation/tutorials, test the full workflow, and ship the public release.

This tool was always awesome, but OP is right, it could use an AI refresh. OpenDCL shreds with React UI’s and if this standalone generator had LLM integration, it would be extremely helpful to builders who want to visualize & vibe code complex UI’s in real time.

I love the idea of pre-made templates, but also saved templates that can be resurfaced quickly. I think maybe with a combination of a UX with a good flow that’s easy to edit with, and the option to use LLM when needed, could be the sweet spot for AI token conservation.

VOXEL — Technical Feasibility

VOXEL Technical Evaluation — Round 1

Hi @szjanko — You have solid credentials (shipped the original tool, DAO grant delivered). I need clarity on a few technical areas:

Round 1 Questions

1. AI Output Validation

You mention “validated structured patches” — what’s the actual validation pipeline?

  • Schema format? (JSON schema, TypeScript types?)
  • How do you prevent the AI from hallucinating non-existent React-ECS components or invalid props?
  • Error handling: retry, fallback to templates, or show error?

2. Mobile DCL Compatibility

DCL now has iOS + Android clients. Will generated code work on mobile (touch targets, portrait layouts, screen sizes)? Or desktop-only for now?

3. Scope vs. Timeline

You’re bundling AI features (prompt-to-UI + chat editing) PLUS undo/redo, shortcuts, Dropdown, 6+ templates, onboarding, .tsx export improvements. As a solo dev with a full-time day job, what’s your realistic weekly hour commitment? This feels like either a full-time 90-day sprint or a 6-month part-time build.

4. Differentiation from OpenDCL

OpenDCL (GitHub - dcl-regenesislabs/opendcl · GitHub) already generates SDK7 code including React-ECS UIs via chat. Your tool is visual-first with scoped chat editing. Can you articulate more specifically:

  • What workflows does a visual canvas + scoped chat enable that pure chat-based generation doesn’t?
  • Are you targeting a different user persona (more designer-focused vs. developer-focused)?
  • What’s the “killer feature” that would make someone choose UI Studio over just prompting OpenDCL?

I want to make sure this is genuinely additive to the ecosystem and not redundant.

5. Existing Code Quality

  1. The AI will not generate raw React-ECS code directly. The validation pipeline is:

    -User prompt goes to OpenRouter.

    -Model returns structured JSON only.

    -JSON is validated against a strict Zod schema derived from the studio’s internal Div element model.

    -Validated patches are applied to UiElementContext.

    -The existing deterministic exporter generates @dcl/sdk/react-ecs code.

    The schema will whitelist supported element types only: container, label, button, input… etc…

    This prevents hallucinated React-ECS components or invalid props because the model never gets to write SDK JSX. It can only propose a patch to the studio’s internal UI tree. If the model outputs an invalid code, the patch is rejected before it reaches the canvas.

    Error handling will be:
    -Validate.
    -If invalid, retry once with the validation errors included.
    -If still invalid, show a clear error to the user and do not modify the canvas.

    So the exported SDK code remains generated by the studio, not by the LLM.

  2. The UI Studio editor interface itself will remain desktop / wide-browser focused for now. The current visual editor is not designed for touch-first editing, and making the editor fully mobile-friendly would be out of scope for this grant.

    The generated DCL UI code, however, will be mobile aware. The studio already has an “Auto Scale” path using UiCanvasInformation / scaleFontSize, and this upgrade will build on that.

  3. 15-20 hours per week. The original DCL UI Studio grant was delivered with similar scope discipline, and the existing app, deployment, exporter, Supabase setup, and domain are already live. This grant is an upgrade to a functioning product, not a new product from scratch, so I am confident in being able to deliver on the milestones over the 90 day timeline.

  4. I see OpenDCL as complementary, not redundant. OpenDCL is closer to a general chat based SDK7 generation assistant. UI Studio is visual first and UI specific.

    The workflow difference is important:

    OpenDCL: prompt - generated code.

    UI Studio: prompt - editable visual canvas - manual drag/resize/tweak - scoped chat edits - deterministic React-ECS export.

    That enables workflows pure chat does not handle well:

    -pixel/layout iteration by eye,

    -dragging and resizing instead of re-prompting,

    -selecting one exact element and asking for a small change,

    -preserving manual edits instead of regenerating a whole file,

    -using templates and visual hierarchy as the source of truth,

    -letting non-coders create UI without reading SDK code.

    The target user is also different. UI Studio is aimed more at creators, designers, artists, and gameplay builders who know what UI they want but do not want to hand code React-ECS layout. Developers can still use it as a rapid UI prototyping/export tool, but the killer feature is:

    AI generates an editable visual UI, not just code.

  5. The repository is public: GitHub - szilardjanko/ui-design-studio · GitHub . The app is also live at www.uistudio.app and has been kept online for over a year after the original grant finished.

    Current automated test coverage is limited. The original project was developed and validated primarily through manual testing, community feedback, and live usage. For this grant, I plan to add the missing automated safety net specifically around the new risk areas:

    -schema validation tests,

    -patch application tests,

    -generator snapshot tests,

    I plan to improve the editor state architecture by moving the canvas state and history system to a dedicated Zustand store. Undo/redo will be implemented as a snapshot-based history stack around the Div[] UI tree: before each meaningful edit, the current tree is pushed to past; undo restores from past and moves the current tree to future, redo does the reverse. Drag and resize interactions will create one history entry at the end of the interaction, not one per mouse movement, etc.
