About
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

About
Third-party APIs change while your code depends on them: a model ID is retired, a field is removed, or an API version reaches end of life. Dependabot updates package versions, but it does not tell you which lines call the changed API.
Upseam does. It reads vendor changelogs and deprecation notices for Stripe, Shopify, OpenAI, Anthropic, and Gemini, matches them against JavaScript, TypeScript, and Python code, and identifies the affected lines.
Then it opens a pull request with the fix. It never pushes to your default branch. In Ask mode (the default), you approve each fix before a pull request opens, including simple fixes such as a renamed model ID.
Install the GitHub App or run a one-off local report with npx @upseam/cli inspect. The local report requires no account or installation. Upseam is free during the beta.
