Release Notes
Notable changes to how TeqSeq is built, deployed and hosted.
Current version: v1.2.0New Calculator utility
Use a browser-based calculator with keyboard controls, parentheses, percentages, powers, square roots, reciprocal/sign controls and memory. Completed calculations are retained locally, can be restored or cleared, and can be downloaded as a TXT history.
Try the CalculatorNew Direct Video Downloader tool
Prepare authorized direct video file downloads in your browser with progress tracking, a 15-minute duration limit, and a save option when ready.
Try the Video DownloaderNew Password Generator tool
Create random passwords in your browser, choose the length and character types, and copy the result. Each selected character type appears at least once.
Try the Password GeneratorNew Validators developer tools
Developer Tools now includes a Validators category for JSON, HTML, CSS, JavaScript and TypeScript — paste code and get a clear valid/invalid verdict, with the parser’s own error message (including line and column) shown when something is wrong. These reuse the same real parsers as the existing formatters (Prettier’s HTML, CSS, JS and TS parsers, plus native JSON.parse) rather than a second, separate validation layer.
Try the JSON ValidatorNew GraphQL Formatter developer tool
Developer Tools now includes a GraphQL Formatter, powered by Prettier’s GraphQL plugin — paste a messy or minified query and get it beautified with consistent indentation.
Try the GraphQL FormatterNew SVG Previewer developer tool
Developer Tools now includes an SVG Previewer. Paste SVG markup or load an example to see the artwork rendered in an isolated image preview.
Try the SVG PreviewerSix new minifier developer tools
Developer Tools now includes minifiers for JSON, JavaScript, TypeScript, CSS, HTML and SVG, showing a size comparison for each result. JavaScript and TypeScript use real minification (via Terser) rather than simple whitespace removal, and TypeScript is first stripped of its types before minifying.
Try the JavaScript MinifierNew YAML Formatter developer tool
Developer Tools now includes a YAML Formatter, powered by Prettier — paste messy or inconsistently indented YAML and get it normalized correctly, since YAML’s whitespace-significant syntax needs a real parser rather than a simple indenter.
Try the YAML FormatterNew JavaScript and TypeScript Formatter developer tools
Developer Tools now includes JavaScript and TypeScript Formatters, powered by Prettier — paste messy or minified code and get it beautified correctly, including template literals, regular expressions and generics that simpler formatters often get wrong.
Try the JavaScript FormatterNew CSS Formatter developer tool
Developer Tools now includes a CSS Formatter — paste messy or minified CSS and get it beautified with proper indentation, nested @media blocks, and consistent spacing, with an example snippet to get started.
Try the CSS FormatterNew HTML Formatter developer tool
Developer Tools now includes an HTML Formatter — paste messy or minified HTML and get it beautified with proper indentation, with an example snippet to get started and a one-click copy for the result.
Try the HTML FormatterBranded loading animation for slower pages
Pages that take a moment to load, such as admin pages, now show a spinning TeqSeq gear animation flipping between "teq" and "seq" instead of a generic skeleton.
New HTML Previewer developer tool
Developer Tools now includes an HTML Previewer alongside the JSON Formatter — paste HTML and see it rendered live in a sandboxed preview, with three example snippets to get started.
Try the HTML PreviewerTerms of Service and clearer legal navigation
TeqSeq now includes a dedicated Terms of Service page. The footer provides direct access to the Terms of Service alongside the Privacy Policy, Contact, and other legal information.

Current release: core feature set
TeqSeq 1.1.0 brings together the JSON Formatter developer tool, an admin view toggle for previewing internal-only content, dedicated Privacy Policy and Imprint pages for legal compliance, and a new Contact page with a validated form for reaching the team directly — alongside links out to the wider TeqSeq toolbox (Quiz Quest Hub and Nihongo Tech).
Migrated hosting from Amazon S3 to AWS Amplify
TeqSeq previously shipped as a static export synced to an S3 bucket, served through a hand-configured CloudFront distribution and deployed by running the AWS CLI by hand. It now runs on AWS Amplify Hosting compute: pushing to the main branch on GitHub deploys automatically, Amplify manages the CDN, TLS and caching without manual CloudFront invalidations, and the app runs as a full Next.js server instead of a static export, which unlocks server-only features such as dynamic metadata routes and request-time rendering.
