Free Solana Tools I Built That Actually Get Used

I've been building free Solana tools over the past few months. Some of them get decent traffic. All of them funnel into paid products. Here's the stack: Free Tools (SEO traffic drivers) Wallet Balance Checker — Enter any Solana address, see SOL balance and all token holdings instantly. devtools-site-delta.vercel.app/sol-balance Price Tracker — Live SOL price + look up any token by mint address via Jupiter API. devtools-site-delta.vercel.app/sol-price Airdrop Checker — Scan any wallet for token holdings — find unclaimed airdrops and forgotten tokens. devtools-site-delta.vercel.app/airdrop-checker Token Safety Scanner — Score any token 0-100 on rug pull risk signals. Free tier is 10 scans/minute. devtools-site-delta.vercel.app/is-safe Paid Products (revenue) Each free tool has a CTA at the bottom pointing to paid products: Trading Bot (free + 1% fees) — t.me/solscanitbot Sniper Service (0.2-5 SOL/month) — /sniper Whale Tracker (free + premium) — /whale-tracker Payment Buttons (2% per tx)
