Automation and integrations decision
Save Bulk Gmail Attachments
A competent developer can build and maintain a useful replacement in about a week; the vendor's main durable advantage is an advertised CASA security attestation and existing store presence, not infrastructure or proprietary data, so self-hosting a replacement is realistic.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Select emails in Gmail → extension fetches attachments → upload to Google Drive or generate local ZIP → show progress and resume on reconnect.
What it still won’t have
- Google CASA Tier 2 security attestation (audit/certification)
- Chrome Web Store history, reviews and existing user trust
- Polished UX refinements and edge-case polish for very large batches
- Enterprise deployment support and in-extension paid subscription plumbing already tested
What remains hard
- Compliance and regulation

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a Chrome extension (Manifest V3) in TypeScript + React for the injected Gmail UI, use Google's OAuth2 flows and Gmail/Drive REST APIs, store session state in IndexedDB, and implement resumable chunked uploads to Drive plus local ZIP creation via jszip. Core features in scope: multi-email selection UI, show per-email attachment counts, one-click 'Save All' to Drive with year/month auto-folder creation, local ZIP download option, resumable uploads/session persistence, and in-extension Pro-feature gating. Out of scope: automated server-side processing, third-party payment processor integration beyond opening a secure hosted payment page, and obtaining Google CASA accreditation. Include error handling, exponential backoff for API calls, unit/integration tests for the pipeline, and CI build + instructions to package and publish to Chrome Web Store.
