v0.2.0: 7 New Developer Utilities, 45+ Technical Guides, and Platform Indexing

What's New

7 New Developer Utilities (Expanding to 95 Tools)

We are excited to release wtool.dev v0.2.0, introducing seven major developer tools designed to streamline daily network debugging, container security auditing, schema modeling, and asset optimization. With this release, wtool.dev now provides 95 specialized developer utilities running privately and securely in your browser.

• JSON Schema Visualizer: Transform complex JSON Schemas into interactive visual hierarchy diagrams, collapsible tree explorers, and auto-generated technical documentation. Includes a one-click realistic mock data generator and code export panel supporting Draft-04 through Draft 2020-12 specifications.
• CIDR & Subnet Calculator: Plan and audit cloud network topologies with an interactive 32-bit visual bitmask explorer. Subdivide parent CIDR blocks into child subnets with the subnet splitter, test IP address containment, and export subnet allocation tables directly to CSV and Markdown.
• Dockerfile Linter: Audit Dockerfiles against industry security benchmarks and container best practices. Identify root execution risks, credential leaks, inefficient cache layer ordering, and missing package manager cleanup steps with actionable auto-fix suggestions.
• Image Converter: Convert and compress images across WebP, AVIF, PNG, JPEG, and SVG formats. Features client-side in-browser canvas and WASM transcoding for complete privacy, high-fidelity server conversions, batch queue processing, and customizable dimension/quality parameters.
• OpenAPI to TypeScript Generator: Convert Swagger 2.0 and OpenAPI 3.0/3.1 specifications into strongly-typed TypeScript interfaces, request bodies, query parameters, and response schemas ready to drop into frontend and backend applications.
• SSL/TLS Certificate Decoder: Inspect X.509 certificates and PEM blocks, verify Subject Alternative Names (SANs), check certificate expiration timelines, evaluate root-to-leaf trust chains, and diagnose remote server TLS configurations.
• WebSocket Client & Frame Tester: Test and debug real-time WebSocket endpoints with custom headers, frame logging, payload templating, ping/pong latency measurements, reconnection simulators, and exportable client snippets in Node.js, Python, and Go.

45+ Comprehensive Technical Engineering Guides

Navigating distributed systems, web security standards, and modern API protocols often requires deep reference documentation. In this release, we've launched our new Technical Guides Library containing 45+ production-ready guides with practical code examples, security checklists, and debugging strategies.

The new guides library is accessible directly through our interactive Guides Directory, featuring instant client-side search, category filtering, reading time estimates, table-of-contents navigation, and context-aware links to related developer tools. Featured topics include:

• Networking & Security: Subnetting & CIDR calculations, DMARC/SPF/DKIM email deliverability, SSL certificate troubleshooting, HMAC webhook verification, and CSP header policies.
• Data & API Protocols: JSON Schema to Zod/Pydantic transformations, GraphQL type generation, OpenAPI automation, and Server-Sent Events vs. WebSockets trade-offs.
• DevOps & Containers: Dockerfile multi-stage build optimization, Docker Compose to Kubernetes migrations, and GitHub Actions workflow debugging.
• AI Engineering: LLM token budgeting, prompt caching cost reduction, and structured JSON output schema validation.

Platform Performance, Sitemap & IndexNow Synchronization

We have upgraded our platform indexing infrastructure to ensure instantaneous search engine visibility for all developer resources. With automated sitemap generation and IndexNow ping integrations, updates across all 95 tools, category hubs, and engineering guides are indexed faster than ever.
