Bun
Bun is a fast, all-in-one JavaScript, TypeScript, and JSX toolkit that ships as a single executable and combines a high-performance runtime, package manager, test runner, and bundler designed as a drop-in replacement for Node.js with broad compatibility and dramatically reduced startup times and memory usage. Written in Zig and powered by Apple’s JavaScriptCore, Bun can execute JavaScript/TypeScript files, scripts, and packages with significantly faster performance than traditional tooling while supporting zero-config TypeScript, JSX, and React out of the box. Its built-in package manager installs dependencies up to 30x faster than npm with workspaces, global caching, migration support, and dependency auditing. Bun’s test runner is Jest-compatible with built-in coverage and concurrent execution, and the bundler processes TypeScript, JSX, CSS, and more without configuration, including support for single-file executables.xx

Email-Validation.org
Email-Validation.org is a web-based email verification service for businesses, marketers, and developers. It checks individual addresses through a REST API and accepts bulk lists through its dashboard and API, returning statuses and reasons to help users identify valid, invalid, risky, or unresolved addresses before using a mailing list. The service includes a credit-based usage model, webhooks, a JavaScript/TypeScript SDK, and a remote Model Context Protocol server for compatible AI clients. Users can validate addresses, submit bulk jobs, inspect results, and manage credits. Credits are purchased in one-time packs rather than a standard subscription; each credit covers one address, unresolved results are free, and purchased credits remain valid for 24 months. New accounts can receive up to 500 free credits, subject to signup eligibility. The service is intended for business email-list hygiene and application workflows.
