A visual self-hosted product still approaching live trading compared with an established open-source live framework.
KryllOS is easier to approach visually but remains Limited Availability for live bot use. Freqtrade requires Python and infrastructure skill but has verifiable public code, a GPL license and current live connectors.
Availability note: KryllOS is currently classified Limited Availability. Confirm the current route before relying on feature or pricing comparisons.

Key differences in practice
Architecture, operating responsibility and evidence matter alongside the feature list.
Current availability
This comparison does not import features from the discontinued historical Kryll cloud platform. KryllOS is evaluated only on its current editor and testing scope. Freqtrade's live runtime and dry-run are current, so the products are not feature-equivalent today.
Strategy development
KryllOS uses a visual editor and companion-style backtest results. Freqtrade uses Python strategies, configuration, historical tests and Hyperopt. Visual authoring can reduce coding friction; Python exposes deeper custom logic.
Security and source model
Both place operations on user infrastructure. KryllOS describes local keys and a future open-source direction, but this review did not establish a current repository and license. Freqtrade publishes GPL code. Neither public code nor local hosting substitutes for host hardening.
Pricing and users
KryllOS is currently free, while Freqtrade is free GPL software. Infrastructure and operator time remain costs. KryllOS fits visual researchers willing to wait for documented live availability; Freqtrade fits technical users needing a live framework now.
Limitations
KryllOS cannot yet be treated as a production live replacement for historical Kryll. Freqtrade has a steeper coding and operational burden. Backtests in either system remain vulnerable to overfitting and execution assumptions.
Features and target users
The scores are comparable; the workflows are not identical.
KryllOS
Strategy Editor, backtest, multi-backtest, VPS deployment and file management are available. Futures, portfolio, paper trading, live trading, plugins, marketplace and AI agent are still upcoming on the current page.
Best aligned with- Users researching visual strategies
- Technical users evaluating the KryllOS reboot
Freqtrade
Freqtrade combines Python strategies, historical data, backtests, hyperoptimization, dry-run, FreqAI and live execution in one self-hosted system.
Best aligned with- Python strategy developers
- Users who want local control
Security and custody
Permissions and architecture matter more than security slogans.
KryllOS
KryllOS moves runtime responsibility to the user's workstation or VPS. Local custody is not automatic safety: exposed SSH, weak host controls, dependencies and backups can compromise future trade credentials.
Current research/backtesting is local. Future live execution is described as self-hosted with funds at exchanges.
Security score 68/100Freqtrade
Freqtrade provides strong visibility and local control, while explicitly warning that its web interface should not be directly internet-exposed.
Funds remain at connected exchanges while credentials and the runtime remain on user-controlled infrastructure.
Security score 78/100Pricing, bot types and limitations
KryllOS
Pricing: KryllOS is currently free, with no subscription or trading commission

Different workflows create different trade-offs.
Freqtrade is the current live-execution choice for capable Python operators; KryllOS is the more approachable visual research environment in active development. Reassess only after KryllOS publishes generally available live trading and connector security documentation.
