    I built a pool-based proxy that hacks Claude Code's pricing tiers. To actually use Claude Code you need Max at $200/mo, and then most of that capacity sits idle anyway. So ClawPool lets subscribers pool their OAuth tokens and earn up to $120/mo from the spare capacity. Everyone else gets Opus, Sonnet, all models for $8/mo. Setup — they actually support proxies themselves via standard env params: export ANTHROPIC_AUTH_TOKEN="your-pool-key" export ANTHROPIC_BASE_URL="https://proxy.clawpool.ai" claude

    Hey HN, I built an alternative to Google translate that's fast, accurate, and 1/30th the price. 20+ supported languages, not billed until 100k tokens, and already used thousands of times with real language learning users. The landing page has a demo for you to test performance yourself for free with no card required. (Also landing page says 1/13 the price because had to account for all 3 big names, with varying prices each). I built this as a workaround for my language learning startup, and it was perfect at a fraction of the cost. Hopefully it can help other devs in accessibility…

    Hi HN, I'm Ben / Tiny Projects (I once posted here about buying 300 emoji domains from Kazakhstan…). For the past 3 years I've been solo bootstrapping PromptBase, an AI marketplace with 450k+ users. At the peak, I was burning $9,400/month in opaque Stripe Connect fees for seller payouts, so I built Zoneless to replace it: - GitHub: https://github.com/zonelessdev/zoneless - Website: https://zoneless.com Zoneless is a free, open-source (Apache 2.0) drop-in replacement for the payout part of Stripe Connect. It allows you to pay marketplace sellers…
