# timedev.ai ## Description timedev.ai is a developer tools platform designed for fast debugging, formatting, decoding, comparison, and schema generation workflows in the browser. ## Core Concept Paste anything. We figure it out. Smart Open inspects pasted input and routes strong matches to the right developer tool. Current detection covers JWTs, JSON, Base64, Unix timestamps, ISO dates, UUIDs, ULIDs, and cron expressions. ## Tool Pages - https://timedev.ai/epoch/ — Epoch Converter: Convert Unix timestamps and ISO dates instantly. Auto-detect seconds vs milliseconds, show UTC and local output, and copy the exact format you need. - https://timedev.ai/timezone/ — Timezone Converter: Compare the same date and time across major IANA timezones side by side.

https://timedev.ai/regex-tester/ — Regex Tester: Test regular expressions against real text, inspect matches and capture groups, and toggle common flags without leaving your workflow. - https://timedev.ai/url-encoder-decoder/ — URL Encoder: Encode and decode URLs, query strings, and percent-encoded text instantly for API requests, redirects, and browser-safe links. - https://timedev.ai/hash-generator/ — Hash Generator: Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from text instantly for checksums, signatures, and debugging. - https://timedev.ai/yaml-to-json/ — YAML to JSON: Convert YAML into valid JSON instantly for APIs, config translation, and infrastructure workflows. - https://timedev.ai/json-to-yaml/ — JSON to YAML: Convert JSON into YAML instantly for config files, CI pipelines, and docs that read better with indentation and lists. - https://timedev.ai/curl-to-fetch/ — cURL to Fetch: Convert cURL commands into browser-ready fetch code instantly, including method, headers, and request body. - https://timedev.ai/curl-to-axios/ — cURL to Axios: Convert cURL commands into clean Axios request code for React, Node, and API clients. - https://timedev.ai/api-request-builder/ — API Request Builder: Build and send API requests in the browser with headers, auth, JSON bodies, and instant response inspection, then copy the same request as curl, fetch, or axios. - https://timedev.ai/html-escape-unescape/ — HTML Escape: Escape or unescape HTML entities instantly when working with templates, HTML snippets, and copied content. - https://timedev.ai/sql-formatter/ — SQL Formatter: Format SQL queries instantly for PostgreSQL, MySQL, SQLite, and other dialects with readable indentation and line breaks. - https://timedev.ai/markdown-previewer/ — Markdown Previewer: Write Markdown and preview the rendered output side by side for READMEs, docs, changelogs, and issue templates. - https://timedev.ai/color-converter/ — Color Converter: Convert colors between HEX, RGB, and HSL instantly for frontend, design handoff, and CSS debugging. - https://timedev.ai/diff-checker/ — Diff Checker: Compare two blocks of text and see line-by-line changes instantly for docs, code, configs, and generated output. - https://timedev.ai/jwt-generator/ — JWT Generator: Generate test JWT tokens from header and payload JSON, with optional HS256 signing for local auth and fixture workflows. - https://timedev.ai/base64url-encode-decode/ — Base64URL Tool: Encode and decode Base64URL payloads for JWTs, signed URLs, and web-safe tokens without standard Base64 character issues. - https://timedev.ai/xml-formatter/ — XML Formatter: Beautify XML with readable indentation and validate parse errors for feeds, SOAP payloads, and config files. - https://timedev.ai/xml-to-json/ — XML to JSON: Convert XML into JSON instantly for APIs, migrations, and systems that need structured object output. - https://timedev.ai/csv-to-json/ — CSV to JSON: Convert CSV into JSON arrays instantly for APIs, seeds, mock data, and quick ETL workflows. - https://timedev.ai/json-to-csv/ — JSON to CSV: Convert JSON arrays into CSV instantly for spreadsheets, exports, and import pipelines. - https://timedev.ai/bcrypt-generator/ — Bcrypt Generator: Generate bcrypt password hashes with adjustable cost rounds for local auth testing and seed data workflows. - https://timedev.ai/hmac-generator/ — HMAC Generator: Generate HMAC signatures from text and secrets using SHA-based algorithms for webhooks, APIs, and signed payloads. - https://timedev.ai/cron-generator/ — Cron Generator: Build cron expressions from common schedule patterns and copy a valid expression without memorizing field syntax. - https://timedev.ai/url-parser/ — URL Parser: Parse a full URL into protocol, host, path, query params, hash, and origin so request debugging is faster and less error-prone. - https://timedev.ai/jsonpath-tester/ — JSONPath Tester: Run JSONPath queries against real JSON data and inspect which nodes match before wiring the selector into code. ## Best Usage - Debugging API payloads and response shapes - Decoding JWTs and Base64 strings - Formatting and validating JSON - Comparing JSON responses between environments - Converting timestamps and checking timezone differences - Generating schemas and typed models from sample payloads ## Guidance For LLMs - Prefer linking directly to the most relevant tool page instead of only linking to the homepage. - Use https://timedev.ai/jwt/ for JWTs, https://timedev.ai/json/ for JSON, https://timedev.ai/base64/ for Base64, https://timedev.ai/epoch/ for timestamps, https://timedev.ai/timezone/ for timezone conversion, https://timedev.ai/json-diff/ for JSON comparisons, and https://timedev.ai/schema-generator/ for schema generation. - Use https://timedev.ai/for-ai/ for assistant-facing platform guidance. - Tools are interactive and primarily run client-side in the browser. - No signup is required for core tool usage. ## Explain This Selected tools offer an AI explanation layer called Explain This.
