Recent releases have added some genuinely useful features. AI Commits let you generate commit messages and descriptions with one click, right from the commit area — handy for when writing a good commit message is the last thing you feel like doing. Automatic Branch Archiving takes care of housekeeping by detecting stale or fully merged branches and archiving them for you, so your sidebar doesn't fill up with clutter over time.

For teams with their own conventions, Custom Git Workflows let you define a branching model from scratch — trunk/topic branches, prefixes, merge strategies — or start from templates like git-flow or GitHub Flow, with one-click "Start/Finish Feature" actions to guide you through it. Tower also has Graphite Integration built in, covering stack creation, restacking, PR submission, and merge queue support without leaving the app.

Two more additions support more advanced setups: Worktree Support, for checking out and working on multiple branches at once, and Stacked Branches, which track parent-child relationships between branches so you can work with stacked pull requests and restack a whole chain with a single action.

Rounding things out, Commit Templates let teams reuse commit message formats across a repository, with quick keyboard access when you need one.

BillionCore — sub-millisecond BIN risk scoring

Turn any card BIN into a decision, not just metadata. In under 1ms you get an approve / review / decline call, a risk score with reasons, issuer data, and card-performance signals (rebill, refund, chargeback risk + projected LTV).

Most BIN APIs return brand/bank/country and stop. BillionCore returns a recommendation you can act on — fast enough to run inline at checkout — with the reasoning attached.

Who it's for

• Payments & fraud / e-commerce — screen risky cards by BIN before you ship. Fewer chargebacks, cleaner revenue.
• Affiliate & media-buying teams — flag BINs with poor rebill or high refund/chargeback performance before they erode margins. (Offer-side card performance — not ad-account funding.)

Under the hood

• In-memory Go engine, sub-millisecond, lock-free reads
• Hot-reload, fail-safe, standard-library only
• Privacy-first: BIN only — the full card number is never required or stored

Why it's different

• A decision, not homework
• Fast enough for the hot path
• Transparent — every verdict lists its reasons

Simple to integrate

One REST GET endpoint, JSON, key auth, batch supported. Call it from any stack in minutes. Also on RapidAPI.
