Best alternatives to Airtight in 2026
Most portfolio trackers ask you to connect exchange accounts or paste in API keys so a company's servers can watch your holdings for you — which means a third party now has a live view of your crypto wealth. Airtight takes the opposite approach: it's a single HTML file, like a self-contained mini-app, that you download once and open in your browser. There's no company account, no server processing your trades, and no internet connection required after you've downloaded it — closer to keeping your finances in a personal spreadsheet than logging into a cloud dashboard, except with real portfolio math built in. Under the hood, Airtight runs entirely client-side: transactions are entered manually, or imported from CSV/Excel exports (paid version) from over 70 exchanges and wallets, and profit/loss is computed using FIFO (first-in-first-out) cost-basis accounting, with live prices pulled from an optional CoinGecko API call — the only network request the tool makes, and it's configurable. Data can be encrypted with a password using AES-GCM before being stored locally. The free version caps manual entries at 50 transactions and has no CSV import; the $30 one-time premium version removes the transaction cap and adds bulk CSV/Excel import. It's sold, not open source, and distributed through the sell.app marketplace rather than a traditional SaaS website.
