Snippets leads this release. Not a clipboard: your lifetime library. Diagram Studio follows. Project Atlas is in Mac beta. Anvil is a native developer toolkit for macOS, iPhone, and iPad, built to make everyday formatting, encoding, conversion, and inspection tasks faster. Work with JSON, Base64, URLs, timestamps, JWTs, UUIDs, hashes, regular expressions, strings, SQL, CSV, YAML, QR codes, and more from one focused app. Instead of jumping between web utilities, Anvil keeps common developer workflows close at hand in a fast, native interface. Use Anvil to: Format, validate, repair, and inspect JSON. Encode and decode Base64, URLs, HTML entities, and escaped strings. Convert timestamps, number bases, CSV, YAML, and other structured data. Decode JWTs and inspect token payloads. Generate UUIDs, ULIDs, QR codes, hashes, sample text, and formatted code. Analyze strings, compare text, and clean up data while building or debugging. Anvil is designed for developers who want practical tools without clutter. Whether you are debugging an API response, preparing test data, checking a token, formatting a query, or converting values during development, Anvil gives you a polished native workspace for the small tasks that happen all day.

This update makes Snippet iCloud sync actually work. It recovers expired tokens, retries record conflicts, and no longer says “All changes saved” when a save failed. Edits, imports, and companion, CLI, or URL-scheme writes wake sync. Coming back to the app restarts a dead scheduler. Sync status is honest about your iCloud account, last error, and last upload or download. Other devices can be woken with a silent push (sync still runs the next time you open the app). Snippets tab: groups are tappable again, including after you back out and tap the same group.
