TabTin vs Cryptohopper

TabTin's feature set is built around shared execution: a Main Agent decomposes work into research, build and verification sub-agents that inherit the same goal and rules, and every write is preceded by a Checkpoint that can roll back execution state. Human approval is mandatory before publish or write actions, permissions are enforced per team member and connector, and there are 48 official Skills packages on top of four surfaces: code (reads repos, edits, runs tests with visible diffs), documents (drafting, rewriting, annotation with versions), spreadsheets (turn scattered info into filterable records), and browser (open live pages, extract structured data). Integrations are GitHub plus a browser connector.

Cryptohopper's features are trading mechanics, not task surfaces: automated A.I. algorithms, one-on-one Copy Bot mirroring, DCA, trailing orders, short selling, paper trading on real-time data, backtesting, a no-code Strategy Designer with 130+ indicators, Market Making and Arbitrage on the Hero tier, a multi-exchange Trading Terminal, Smart Trade triggers, and a third-party signals marketplace. It connects to Binance, Coinbase Pro, Kraken, KuCoin, Huobi, OKX, Bybit, Bitfinex, Poloniex, Bitstamp, Gate.io and Zapier. Recent guides on ticker and orderbook data show the MCP server being positioned for AI agents consuming live market data — a developer touchpoint, but still in service of trading, not team productivity. The two products share no functional surface.

TabTin is freemium and open source, distributed as a downloadable release (one version is dated 9.21). The buyer's real cost is setup and operation: someone has to run or self-host it and handle configuration, and no mature third-party integration ecosystem is promised out of the box. There is also no documented public API or CLI for custom automation, so cost shows up as engineering time rather than a license fee.

Cryptohopper is explicitly paid and explicitly not free: the Explorer plan is $24.16/mo after a 3-day trial, and higher capabilities such as Market Making and Arbitrage sit on the Hero tier. It is SaaS only — there is no self-hosted or open-source option — so the trade is subscription predictability and zero hosting work in exchange for no on-premise control. It also offers a free Trading Terminal for managing multiple exchange accounts from one dashboard, which softens the entry price but does not change the paid-bot model. Comparing the two price tags is meaningless: one is a freemium open-source project you operate yourself, the other a recurring SaaS bill for hosted trading automation. Budget the first as headcount hours, the second as a monthly subscription.
