Best alternatives to tokensift in 2026
If you've ever pasted a wall of pretty-printed JSON or a long UUID into a prompt without thinking twice, tokensift is built to catch exactly that habit. Since AI APIs charge by the "token" — small chunks of text — and token counts don't line up neatly with how many characters something has, small habits like extra whitespace or verbose IDs quietly inflate your bill every single time that prompt runs. tokensift works like a code linter, in the spirit of ESLint, except instead of flagging bad code style, it flags bad prompt style — pointing out, for instance, that a UUID costs 18 tokens when a short ID would cost 3. Technically, tokensift is a zero-dependency TypeScript library and CLI that tokenizes prompts offline and deterministically, using OpenAI's actual BPE vocabularies for exact counts on GPT-4o/4/3.5/o1/o3, and calibrated estimates (about 7.6% mean error) for Anthropic's Claude models. It ships 20 built-in detection rules — for repeated blocks, base64 blobs, and filler text among others — and translates each finding into an actual dollar-cost estimate, not just a token count. It supports custom rules, CI integration with GitHub/SARIF/Markdown output, baseline regression tracking, per-file token budgets, and test matchers for vitest and jest. It runs anywhere JavaScript runs: Node.js, Deno, and edge runtimes like Cloudflare Workers.
