Nothing you paste is uploaded
Developer tools that never see your data.
Paste in, transform, copy out. Every tool runs locally in your browser — there is no backend server to receive, inspect, or log your code.
try it
import { z } from "zod";
export const UserSchema = z.object({
id: z.int(),
email: z.email(),
joined: z.iso.date(),
plan: z.unknown().nullable(),
});
export type User = z.infer<typeof UserSchema>;
All tools
Schemas & types
- JSON to ZodTurn JSON samples into a Zod schema, with optional and nullable inferred separately from several samples.
- JSON to PydanticGenerate Pydantic v2 models from JSON samples, with snake_case fields, aliases and optional handled correctly.
- JSON to TypeScriptGenerate TypeScript interfaces from JSON samples, keeping optional properties and nullable values distinct.
- JSON to JSON SchemaGenerate a draft 2020-12 JSON Schema from JSON samples, with $defs, required keys and format keywords.
Tables & data
- Markdown table to CSVConvert a GitHub-flavored Markdown table to CSV, edit the cells in a grid, and download the result.
- Markdown table to ExcelTurn a Markdown table into a real .xlsx file with a bold frozen header, autofilter and column widths.
- Markdown table to JSONConvert a Markdown table into an array of JSON objects, with numbers and booleans inferred from the cells.
- Markdown table to SQLGenerate CREATE TABLE and INSERT statements from a Markdown table, for PostgreSQL, MySQL, SQLite or SQL Server.
- Markdown table to HTMLConvert a Markdown table to a clean HTML table with thead, tbody, escaped entities and column alignment.
- CSV to Markdown tablePaste CSV, TSV or spreadsheet rows and get a clean, aligned Markdown table. The delimiter is detected for you.
Icons & SVG
- SVG to React NativeConvert SVG markup into a react-native-svg component, with unsupported features listed rather than silently dropped.
- SVG to FlutterConvert SVG markup into a Flutter CustomPainter, with paths replayed as canvas calls and colors as ARGB.
- SVG to Jetpack ComposeConvert SVG markup into a Jetpack Compose ImageVector, with the f-suffixed literals the path DSL requires.
- SVG to SwiftUIConvert SVG markup into a SwiftUI Shape or View, with elliptical arcs converted to cubic curves.

Architecture & Privacy
Why in-browser execution matters for developers
Developer tools frequently handle proprietary data: internal JSON schemas, database exports, JWT tokens, SVG assets, and confidential API models. Most conventional online converters process conversions server-side via remote cloud microservices. This introduces unintended security exposure, as server endpoints routinely log request bodies in infrastructure monitors, caching layers, or debugging logs.
DevForge Hub reverses this paradigm. Every utility is compiled and bundled to run entirely inside your browser client. Using Web Workers for intensive transforms and local JavaScript parsers for real-time validation, processing occurs within your device’s isolated sandbox with zero egress traffic.
| Feature / Metric | DevForge Hub (Client-Side) | Standard Cloud Converters |
|---|---|---|
| Data Transmission | 0 HTTP requests (100% on device) | Uploaded via HTTP POST to remote API |
| Data Retention Risk | Zero server storage or logging | Possible server logs, caching, or retention |
| Compliance Friendliness | Safe for SOC2, HIPAA, & GDPR | Requires third-party vendor review |
| Execution Latency | Instant local computation | Subject to network latency & cloud queues |
| Offline Operation | Fully operational without internet | Fails when offline or behind firewalls |
Frequently Asked Questions
Everything you need to know about DevForge Hub
- How can I verify that DevForge Hub never transmits my data to a server?
- You can verify this directly in your browser. Open your browser's Developer Tools (F12 or Cmd+Option+I), switch to the Network tab, and run any transform or paste data into any tool. You will see that zero network requests are dispatched carrying your pasted payload. Once the static HTML and JavaScript assets are loaded, execution is 100% contained within your local browser runtime.
- Why is in-browser processing crucial when converting sensitive JSON or schemas?
- Standard online converters transmit code, configurations, database schemas, and JSON samples over HTTP to remote servers. If your payload contains internal architecture details, customer identifiers, proprietary algorithms, or accidental API tokens, sending it to third-party servers introduces compliance vulnerabilities (GDPR, SOC2, HIPAA). DevForge Hub guarantees your data never leaves your workstation.
- Can I use DevForge Hub offline or behind a strict enterprise proxy?
- Yes. Because every tool's logic runs entirely client-side using JavaScript, Web Workers, and WebAssembly, you can load DevForge Hub and immediately disconnect your network. The converters, syntax highlighters, and exporters will continue functioning flawlessly offline, making it ideal for restricted corporate VPNs and air-gapped environments.
- Are the generated code and converters free for commercial use?
- Yes, DevForge Hub is completely free for both personal and commercial software development. You retain 100% intellectual property ownership over all inputs and generated outputs (Zod schemas, TypeScript types, Pydantic models, SQL tables, and mobile vector components). We claim no rights or licensing over your code.
- How are complex conversions (such as JSON to Zod or SVG to SwiftUI) validated?
- Every tool engine in DevForge Hub is backed by an automated test suite verifying deterministic output, valid syntax generation, and schema parsing accuracy. Where certain conversions are inherently lossy—such as complex SVG gradient flattening or approximate curves—our engines explicitly surface diagnostics and warnings rather than silently outputting corrupt code.
- Does DevForge Hub store my pasted code in browser cookies or persistent storage?
- No. What you paste into an editor or tool is kept exclusively in transient browser memory while your tab is open. We do not persist pasted inputs in localStorage or cookies. Only harmless UI preferences (such as your chosen light/dark theme and preferred formatting options) are stored locally on your device.
