Gunbot and Kryll.io are two well–known crypto trading bots, yet they follow very different design philosophies. Gunbot delivers a self-hosted desktop or VPS application with lifetime licensing and deep code-level control, while Kryll.io offers a browser-based visual builder coupled with a pay-per-use cost model. This 2025 comparison highlights their key distinctions so you can decide which platform better fits your trading style, budget, and security requirements.
Core Differences at a Glance
| Feature | Gunbot | Kryll.io |
|---|---|---|
| Deployment | Self-hosted desktop, server, or VPS | Fully cloud SaaS, runs in the browser |
| Pricing Model | One-time lifetime license – starts at $59 (Gunbot Standard) | Pay-as-you-go in KRL tokens plus optional subscriptions from $19 / mo |
| Strategy Types | Spot and Futures Grid, DCA, Indicator Based, Liquidity Provider, Scalping, Trailing, Custom JS | Visual workflow bots built from blocks; marketplace rentals; limited Lua scripting for advanced nodes |
| Custom Scripting | Full JavaScript engine, TradingView webhooks | Lua supported in certain nodes; otherwise drag-and-drop only |
| Exchange Integrations | Native connectors for 25 + major spot and futures venues (see list below) | Roughly 10 centralised exchanges |
| API Key Custody | Local – your API secret never leaves your machine | Stored on Kryll.io servers to execute trades |
Deployment Model and API Key Security
Gunbot installs on Windows, macOS, Linux, or almost any VPS. Because everything runs locally, your API secret (sometimes called the private key) never leaves your hardware. Updates are downloaded, but trade execution happens entirely under your control.
Kryll.io runs inside your browser on Kryll’s servers. For the platform to place trades, you must upload your API keys to their infrastructure. They implement encryption and security measures, yet the custody risk is inherently higher because it is third-party managed.
Bottom line: If you have strict security policies or operate large balances, Gunbot’s local-key model is the safer option.
Pricing: Lifetime vs Ongoing Usage Fees
| Cost Scenario | Gunbot (one-time) | Kryll.io (usage-based) |
|---|---|---|
| First month, light usage | $59 (lifetime) | 0–$19 subscription + KRL used while strategy runs |
| First six months, active daily trading | $59 total | $114 subscription + variable KRL (often $40–$100+) |
| Two-year horizon, frequent trading | Still $59 | Subscription $456 + KRL variable (can exceed a few hundred) |
Gunbot’s fixed-fee structure brings cost certainty. Even if you upgrade to higher tiers later, you still pay only once per tier. Kryll’s model can appear cheaper for occasional entry-level use, but fees compound quickly if you scale up the number of strategies or run them continuously.
Strategy Creation and Customization
Gunbot
- Preset Strategies: Each category (grid, DCA, scalping, indicator based, liquidity provider, trailing) ships with sensible defaults, making it easy to get a bot live within minutes.
- Full JS Engine: Advanced users can code custom indicators, dynamic position sizing, or multi-exchange arbitrage in JavaScript.
- TradingView Webhooks: Any TradingView alert can feed directly into Gunbot for hybrid discretionary-bot trading.
- Backtesting: Local backtesting module allows rapid iteration without risking capital.
Kryll.io
- Visual Blocks: Drag SMA, RSI, or volume conditions onto a canvas, connect actions like “Buy” or “Trail Stop”, and hit deploy.
- Lua Extensions: For edge cases not covered by blocks, certain nodes accept Lua, though the syntax is sandboxed and more limited than full JS.
- Marketplace: Rent community strategies with revenue-share. Good for inspiration, but results vary and rental costs add up.
- Cloud Backtests: Simulations run on Kryll’s servers, counting toward your KRL usage.
Key takeaway: Gunbot favors power users who want total freedom, whereas Kryll.io prioritizes approachability for non-coders.
Supported Exchanges in 2025
Gunbot ships with more than 25 official native connectors. Highlights include Binance, Kraken, KuCoin, Bybit, OKX, Coinbase Advanced Trade, dYdX (v3 and v4), HyperLiquid, and PancakeSwap. Futures coverage spans both USD-M and COIN-M markets where the exchange offers them. This broad reach lets you re-deploy the same strategy across CEX and DeFi ecosystems without rewriting code.
Kryll.io integrates with roughly ten large centralised venues (Binance, Kraken, KuCoin, Coinbase, Bitget, OKX, and a few others). It currently lacks on-chain perpetual decks such as HyperLiquid or dYdX v4.
Feature Highlights You Might Overlook
| Category | Gunbot | Kryll.io |
|---|---|---|
| Version Control | Backup and restore JSON configs locally, track changes with Git if desired | Strategies stored in cloud dashboard; snapshots handled automatically |
| Mobile | Web interface. Optional third-party Telegram bots and Pushover notifications | Official mobile app to monitor running strategies and tweak parameters |
| Latency | Depends on your VPS location – can be optimised for sub-100 ms round-trip to your exchange | Kryll’s servers are fixed; you have less control over proximity to your exchange’s matching engine |
| Licensing | Transferable license keys, upgradeable between tiers by paying the price difference | No lifetime plan; you always pay per usage or subscription |
| Data Privacy | Trade logs, balances, and strategy code live only on your machine | Logs reside on Kryll’s infrastructure – deletion request required if you leave the platform |
Who Should Choose Gunbot?
- Traders who cannot compromise on API secret privacy or need on-prem compliance.
- Power users wanting to script or tweak multi-leg strategies, advanced risk management, or integrate bespoke indicators.
- Teams trading across spot, futures, and emerging on-chain perps on a single codebase.
- People who prefer paying once and owning the software indefinitely.
- Anyone aiming to experiment with liquidity-provider or scalping tactics that require precise timings.
Who Should Choose Kryll.io?
- Visual thinkers who like building flowcharts rather than writing code.
- Casual traders happy to pay only when a bot is live, forgoing a large upfront cost.
- Users who value a centralised marketplace to rent strategies and follow top performers.
- Mobile-first traders who want to babysit their bots from a dedicated phone app.
- Those okay with storing keys and trade data on an external platform.
Verdict
Both platforms automate crypto trading, but they sit at opposite ends of the control–convenience spectrum.
Gunbot is the stronger choice for users who prize security, deep strategy customization, and predictable lifetime pricing. Its self-hosted model keeps your API secret on your own device and its JavaScript engine lets you craft any logic you can imagine.
Kryll.io excels at quick visual strategy assembly and hassle-free deployment, making it attractive for beginners or part-time traders who prefer to avoid server maintenance. The trade-off is higher long-term cost and third-party custody of your keys.
Ultimately, decide whether you would rather own and control every aspect of your trading stack (Gunbot) or trade convenience for ongoing fees and cloud-level simplicity (Kryll.io). Armed with that clarity, picking the right bot becomes straightforward.
