Developer Tools
20 toolsEssential web utilities: JWT debugger, cURL parser, UUID generator, crontab tester, and meta tag builder.
Tool list
2FA Live
Generate Time-based One-Time Passwords (TOTP) in real-time. Paste your Base32 secret to see the current OTP, refreshing every period — compatible with Google Authenticator, Authy, and Microsoft Authenticator.
Key Generator
Generate generic JWT secrets, API keys, and passwords locally, plus clearly marked service-shaped and PEM-shaped test fixtures that are not issued credentials or key pairs.
RSA Key Pair Generator
Generate RSA key pairs (2048, 3072, or 4096-bit) with PKCS#8 and SPKI PEM, OpenSSH public-key, JWK, and SHA-256 fingerprint exports using Web Crypto.
Curl Parser
Parse cURL commands into structured HTTP request details, including method, URL, headers, cookies, query parameters, body, and exportable code.
Cookie Parser
Parse Cookie and Set-Cookie strings, decode encoded values, inspect attributes, and export cookies as JSON, JavaScript, or header text.
Database Connection Checker
Test PostgreSQL, MySQL, MongoDB, and Redis connections, inspect read-only metadata, and convert database URIs for Navicat, TablePlus, DBeaver, DataGrip, Prisma, Laravel, and CLI workflows.
CORS Tester
Check whether an API allows cross-origin requests. Simulate any Origin, method, and headers, run the preflight, and read every Access-Control-Allow-* header the server returns — even when a browser would block the response.
MongoDB ObjectId
Convert, parse and analyze MongoDB ObjectId. Supports single or bulk input (string or object).
MongoDB ObjectId Generator
Generate valid MongoDB ObjectId values randomly, from a timestamp, or in batches for tests, fixtures, and database workflows.
SIP Authorization Tester
Verify SIP digest authentication and generate Authorization header responses with browser-side MD5 calculations.
SIP Message Builder
Build raw SIP requests and responses with editable headers, body content, and automatic Content-Length calculation.
SIP Message Parser
Parse raw SIP messages online and inspect the start line, headers, body, status, method, and protocol fields.
SIP Call Flow Analyzer
Analyze SIP call flows with sequence diagrams, timing metrics, response summaries, and RTP stream hints from SDP.
SIP Header Checker
Validate SIP message headers for malformed Via values, missing branch cookies, Contact hints, Content-Length mismatches, and SDP issues.
SIP Port Simulation Planner
Generate deterministic SIP port report fixtures for selected hosts, ports, and profiles. This browser tool simulates results and does not probe the network.
UUID Parser
Parse, validate, and analyze UUID values across v1, v3, v4, v5, v6, v7, and v8 with timestamp, variant, and byte breakdowns.
UUID Generator
Generate bulk UUIDs for v1, v3, v4, v5, v6, v7, and v8 with standard, uppercase, hyphenless, braces, URN, TXT, and JSON output.
WebSocket Tester
Test WebSocket connections from the browser, send text, JSON, or binary messages, inspect responses, and export session logs.
K6 Script Generator
Generate review-ready k6 starter scripts in the browser. Configure scenarios, stages, requests, checks, thresholds, environment variables, and CSV data before validating the downloaded script in your own k6 environment.
Gatling Script Generator
Generate Gatling Scala starter simulations from the browser. Configure injection profiles, loops, HTTP requests, checks, and CSV feeders, then review and validate the downloaded file in your Gatling project.
