ProfitTrailer vs Gunbot: two closed bots you run yourself

The same shape, metered in different units

Both are closed-source trading bots that you download and run on your own machine, licensed by the month in euros. Both sit in the self-hosted collection and not in open source. The template prints 50 euros against 29 and stops there. The two figures do not buy the same unit.

• ProfitTrailer meters bots. One licence runs three live bots and keeps seven saved configurations. An extra API-key slot is 12.50 euros a month, and the shop's VPS tiers run one to five live bots on top of a licence. The vendor's pages do not say how a live bot maps to an API key. Ask before planning a fourth.
• Gunbot Unlimited meters nothing. The plans page promises "unlimited exchange access". The vendor's FAQ says one licence drives any number of installations sharing one licence wallet, which Gunbot vs HaasOnline works through.

So a trader running one bot pays 50 against 29. A trader running four pays 50 plus a slot or a second licence on ProfitTrailer, and still 29 on Gunbot.

Over a year, as of 24 October 2026:

• Gunbot, monthly through PayPal: 348 euros. Its plans page now also sells prepaid terms in crypto, which do not renew automatically: six months for 174 dollars and twelve for 348.
• ProfitTrailer, billed annually: 449 euros. Month to month it is 600.
• ProfitTrailer, lifetime: 1,999 euros on the homepage. The shop's product page for it read "Out of stock" on 23 October.

Gunbot's currency is not settled. The plans page prints euros for the monthly plan, while its embedded product data and the prepaid links say dollars. ProfitTrailer's is euros everywhere it prints a price, and its /pricing page is a placeholder.

What each one lets you change

ProfitTrailer is configured, not programmed. The logic is fixed: wait for an entry condition, trail the price before buying, trail it again before selling, and average down with DCA. What you choose is which of the 40-plus indicators open and close the trades, up to 26 combined, in a basic or advanced editor. There is no scripting language, and the wiki documents no API for controlling the bot from outside. TradingView alerts reach it through a webhook on the vendor's signal server, with a 5-euro add-on.

Gunbot is configured, then programmed. It ships a library of grid and stepgrid strategies and a builder of mixable buy and sell methods. AutoConfig rewrites settings and rotates pairs on rules you define. Past that sits plain JavaScript, with module imports and filesystem access. It has a REST API with first-party JavaScript and Python SDKs. TradingView alerts arrive by webhook or through an IMAP listener that reads alert emails.

Testing a configuration before it trades

Gunbot has a backtester; ProfitTrailer does not. ProfitTrailer's homepage, product pages and wiki index name none, so paper trading the same configuration on live prices is how you try one. That means a test takes as long as the market takes. Gunbot's Unlimited plan includes the backtesting toolkit. Its documentation also says the historical data covers fewer exchanges than it trades live, and suggests testing a similar market elsewhere when yours is missing. On those venues a Gunbot backtest runs on somebody else's prices, and what a crypto backtest assumes covers the rest.

Where they trade

Both reach Binance, Binance US, Binance Futures, Bybit spot and futures, KuCoin, HTX (both still call it Huobi), Kraken, Kraken Futures and Poloniex. Kraken Futures arrived in ProfitTrailer's 2.6.0 release, which its homepage list does not yet show.

• Only ProfitTrailer: KuCoin Futures and Huobi futures, plus OANDA for forex.
• Only Gunbot: OKX, Bitget, Bitfinex, Coinbase Advanced Trade, Crypto.com, Gate.io, MEXC, BingX, HitBTC, CEX.IO and BYDFi futures, and four decentralised venues: Hyperliquid, dYdX, PancakeSwap and Aster. It also lists Alpaca for US stocks, which this catalogue does not cover.

Gunbot still listed BitMEX after it ceased trading on 23 September 2026. Ignore that row.

The things that keep running after you buy

Where the two differ is in what you rely on after the purchase. On this axis ProfitTrailer is the more conventional product.

A previous build you can reinstall. ProfitTrailer's releases are on GitHub as downloadable zips. On 24 October 2026 the eight most recent ran from 2.6.1, published on 10 October, and 2.6.0 on 8 September, back to 2.5.66 in January 2025, each with a zip of about 112 MB. The notes ask for a backup before every upgrade and warn that a move from 2.4 cannot be undone. Gunbot's downloads page lists every release back to 31.0.3. When its card tried three of the links on 21 September, each returned a page of HTML rather than a zip, so a bad update cannot be undone from the vendor's own archive.

A licence that is only money. ProfitTrailer is a subscription in euros with no wallet involved. Gunbot Unlimited's setup asks for a Gunthy wallet address from the order email, and none of its pricing or setup pages says whether a token balance must be kept there. Its older lifetime licences do require one, which a token threshold is not a price works through. The question is open, not answered either way.

A machine it will run on. ProfitTrailer needs Java 8. Its wiki says Java 9 and later are not supported, which rules out the runtime a fresh machine installs by default. It warns of about 30 GB of traffic a day, and it says plainly that it is not for a point-and-click user. Gunbot ships signed binaries for Windows, macOS and Linux of around 300 MB, and also runs on a Raspberry Pi.

Both vendors also put other people's decisions beside the bot. ProfitTrailer's shop resells two signal subscriptions, and Gunbot's features page announces a copy-trading marketplace as coming soon. Neither is needed to run the software, and this catalogue assesses neither.

Which one, and when

Take Gunbot if you are choosing between the two from scratch. At 29 a month it is the cheaper licence, it does not cap bots or installations, and it trades more than twice the venues, decentralised ones included. It has the backtester, the code layer and the API that ProfitTrailer lacks. Start with one month on PayPal. Before paying for the 348-dollar prepaid year, ask support two things in writing: whether Unlimited needs a token balance, and which currency you will be charged in.

Take ProfitTrailer only if your strategy is a trailing entry with DCA that its indicator set can express, you will run three bots or fewer, and you value two things Gunbot does not offer: a licence with no wallet attached, and last month's build on GitHub to go back to. Take it too if you need KuCoin or Huobi futures or OANDA. Then budget 449 euros a year, install Java 8 on purpose, and paper trade every configuration for as long as you would have backtested it.
