StackSwap

What it does

Most GTM teams waste 30-40% of their stack spend on overlapping tools — and don't know it until renewal season. StackSwap scans your tools in ~60s and tells you exactly what to remove, swap, or keep — with modeled savings per tool, priced from 11 real SaaS vendor datasets. No login. No subscription. Free preview. Unlock the full CFO-ready savings plan when you're ready. Built for RevOps, ops leads, and finance teams cutting stack spend without guessing.

  I built a free AI tool that picks your SaaS tech stack based on budgetFeb 2026 · appstackbuilder.com · ▲6

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
