CodeDrop: fair giveaway codes for V2EX

Make sure the redemption codes you give away reach real users, not scrapers

Problem: Indie developers on V2EX hand out promo codes to promote launches, but the pain is concrete: codes get scraped by bots, some claimers stay silent so everyone else wastes time trying codes one by one, latecomers can't find the redemption link, asking for codes by email leaks privacy, and codes promised to a specific floor get grabbed by someone else. Both sides end up guessing.
Solution: A hosted code pool with a claim flow embedded in the V2EX thread: the OP uploads codes and sets rules (floor, account age, one per user), a browser extension or userscript injects a Claim button, and claiming marks the code used and syncs status back to the thread. No email exchange needed.
Users: Indie developers and small teams who run giveaways on V2EX and similar communities; users who join those giveaways
MVP: Import and dedupe code lists; lock claims by floor and account rules; mark used and show remaining count on claim; export claimer list; a single extension or userscript entry point
Revenue: Free tier of ~50 codes per month, then per-claim or monthly subscription; one-time license for frequent promoters
Why now: AI coding tools have exploded the number of indie builders, so code giveaways are now standard launch tactics while community tooling stays primitive; it's just API reads plus state sync, buildable solo in 2-3 weeks
