🏦 Zerosum v1.5.1 — Account Groups, RTB Clarity & a New Home

Two of the most-requested features — plus a brand-new home for the app. Account groups finally let you organize your accounts the way you think about them. The Ready to Budget card now opens a full breakdown of exactly where this month's money came from. And the app has moved to its own subdomain — cleaner separation, faster marketing site.

📂 Account Groups

Organize your accounts your way. Create your own groups — "Joint", "Work", "Savings buckets", "Kids" — and drop accounts into them. No more flat scroll when your setup grows.
Drag to reorganize. Drop any account onto a different group (same type only), or drag it back to ungrouped. Reorder groups by dragging their header.
Right-click a group header for Rename, Add account, and Delete. Deleting a group returns its members to ungrouped — nothing gets lost.
Flows through everywhere. Analytics filters, account pickers, and the sidebar all respect your grouping. Filter by a group and new accounts added to it later are automatically included.
Fully opt-in. If you don't create a group, nothing changes — the flat list stays the default.

🧮 Ready to Budget Breakdown

Click the info icon on the RTB card to open a full breakdown of where this month's money came from.
See every piece at a glance — last month's leftover, income landed this month, overspending carried forward, For Next Month moves — instead of flipping between months.

🌐 New Home on the Web

The app now lives at app.zerosum.so. Cleaner separation between the logged-in product and the marketing site.
zerosum.so is now a dedicated marketing + help-center site — rebuilt on Astro for instant static delivery, proper SEO (sitemap, structured data, OG cards), and a polished help center that cross-links everything.
PWA heads-up. If you installed Zerosum to your home screen from the old URL, please uninstall and reinstall from app.zerosum.so — PWAs are origin-bound, so the old install opens in a regular browser tab instead of standalone mode.

🛠️ Fixes & Polish

Polar subscription webhooks no longer drop. Fixed a case where a missing customer email could break incoming webhooks mid-flow.
Stack refresh. Upgraded to Node 24, Prisma 7.7, and a handful of dependency majors (lucide-react, echarts, motion, Redis 8, Postgres 18) for performance + security fixes across the board.

📚 Help center

Accounts & Transfers — updated with the new Account Groups section (create, rename, drag-to-reorder, filter behavior)
Zero-Based Budgeting — added the "Ready to Budget breakdown" section explaining each component
The entire help center has been rebuilt on the new marketing site — faster loads, deep links from inside the app land instantly.
