Schema-driven app authoring. Declare. Don't drag-wire.

Retool and AppSmith want you to drag widgets onto a canvas and bind each one by hand. TemplateStudio generates the editor, list, and validator from a 20-line LiteSpec schema.

Widget-on-canvas authoring is hand-binding fatigue.

Build a form in Retool: drag inputs, bind each to a field, write validation per-input, write event handlers for cascading dropdowns. Then do it again. And again. Same conceptual screen, three to five hand-built artifacts.

Worse: those widgets live in the vendor's cloud. You can't git diff your app. You can't promote a screen between environments without lift-and-shift through the vendor's API.

Key features

Declare the schema. Get the app.

LiteSpec generates the entire form.

Declare a model in LiteSpec — fields, types, validation, conditional rules, permissions — and the platform generates a list view, single-record editor, client-side and server-side validation, audit field stamping, REST API endpoint, and authorization gates. Twenty lines of LiteSpec replace 200 lines of widget config.

Visual designer with code round-trip.

Drag-drop canvas for layout-first authoring. Visual edits write Pongo2 markup directly to the template's content field. Switch between visual and code mode at will — both views are live representations of the same underlying template.

Field rules: declarative cross-field behavior.

syncWith, calculate, updateOptions, setValue — no event handlers, no binding-language expressions. Change a dropdown value, watch dependent fields recalculate, options refresh, visibility toggle. All declarative, surveyable from the template editor.

Field Rules tab — declarative client-side rules

Composition via include and extends.

Share fragments across hundreds of templates. Base templates host common chrome; fragments hold reusable form sections. Edit a base once; every template inheriting it updates.

Round-trip between environments.

Templates live in _template_builder — pure MongoDB. The Bulk Compare tool promotes templates between dev / staging / prod the same way you promote application data. Field-by-field diff visibility, selective sync.

What only TemplateStudio offers

What Retool, AppSmith, and Budibase cannot do.

Schema-driven form generation. 20 lines of LiteSpec replace 200+ widget-config lines.

Declarative field rules. Cross-field behavior without event handlers or binding expressions.

Templates live in your MongoDB. No vendor lock-in. Your app is data, not opaque widget JSON.

Bulk Compare promotion. Move templates between envs with the same tool you use for app data.

Visual Designer round-trips to Pongo2. Visual edits write source code; toggle modes freely.

Pongo2 + Goja Code tabs. Full server-side scripting with MongoDB access. Not a sandboxed expression DSL.

Use cases

What teams build with TemplateStudio.

Internal admin tools

CRUD UIs for tenant onboarding, billing review, support triage. Declare LiteSpec, get the editor.

Customer-facing forms

Quote requests, application intake, signup flows. Render at /v/. Field rules drive cascading.

Reports and dashboards

Code tab fetches data via ctx.DB. Content renders charts, tables, KPI cards via Wave CSS components.

Multi-tenant white-label apps

Same template renders across tenants. Each tenant's data in its own MongoDB DB. Routing handled by platform.

Build apps without widget-wiring fatigue.

TemplateStudio replaces Retool / AppSmith / Budibase with a MongoDB-native template editor. Promote between environments with the same tool you use for data.
