Tektii vs QuantConnect
QuantConnect pioneered cloud-based algorithmic trading with the open-source LEAN engine. Tektii takes a different approach — Docker-native strategies, language freedom, and an open-source Trading Gateway for live execution. Here's how the two platforms compare.
The core difference
QuantConnect is built around the LEAN engine — an open-source algorithmic trading engine where strategies must inherit from a base class and use LEAN's API for data, orders, and portfolio management. This means your strategy code is coupled to the LEAN runtime, your language choices are limited to C# and Python, and migrating away requires a rewrite.
Tektii takes a Docker-native approach. Your strategy is a standard container that communicates with the engine via WebSocket and REST APIs. You choose the language, libraries, and tools — the platform doesn't care what's inside the container. This means your strategy code is portable, fits into CI/CD pipelines, and has no dependency on a platform-specific SDK.
The same WebSocket and REST protocol powers both the backtest engine and the open-source Trading Gateway. Your strategy connects to the engine during backtesting and to the Gateway for live trading — zero code changes. The Gateway is free, open-source, and you run it yourself. Even if Tektii disappeared tomorrow, your Docker strategy and the Gateway would still work.
For developers and quant traders who value language freedom, CI/CD workflows, and portable strategies, Docker-native is the modern approach. You get full control over your runtime, zero vendor lock-in, and strategies that deploy like any other production software.
Feature comparison
| Feature | Tektii | QuantConnect |
|---|---|---|
| Language Support | Any (Docker-native) | C#, Python |
| Strategy Packaging | Docker containers | LEAN framework (coupled to LEAN runtime) |
| Execution Engine | Unified protocol — backtest engine + open-source Trading Gateway for live | Unified LEAN engine for backtest and live |
| Backtest-to-Live Parity | Same REST + WebSocket protocol — zero code changes between backtest and live | Same LEAN API for both — generally consistent |
| Data Granularity | Tick-level | Tick-level |
| Asset Classes | Forex today; equities, crypto, and futures on the roadmap | Equities, options, futures, forex, crypto, CFDs |
| Infrastructure | Managed cloud for backtesting; self-hosted Trading Gateway for live execution | Managed cloud or self-hosted (requires LEAN setup) |
| Strategy Portability | Standard Docker containers, no vendor lock-in | Locked to LEAN API — requires rewrite to leave |
| Broker Integration | Alpaca, Binance, Oanda, Saxo via open-source Trading Gateway (free to self-host) | 20+ brokers |
| Live Trading Cost | Free — open-source Trading Gateway, self-hosted | Requires paid live trading node ($20-40+/mo per algorithm) |
| Pricing | Free tier, from $29/mo | Free tier, paid tiers from $8/mo (compute nodes extra) |
| Version Control | Built-in version tree | Git integration |
| Research Environment | Use your own tools — any IDE, any library, any framework | Built-in Jupyter notebooks |
| Open Source | Trading Gateway is open source (Elastic License 2.0) — inspect, modify, and self-host. Your strategy code stays private in isolated Docker containers. | LEAN engine is open source (Apache 2.0). Cloud platform is proprietary. |
| Community | Dedicated community with direct founder access | Large (active forums and community) |
When to choose Tektii
- •You want to use any programming language — Rust, Go, C++, Python, or anything that runs in a Docker container
- •You want portable strategies with no vendor lock-in — your Docker image works anywhere
- •You prefer CI/CD-native workflows where strategies deploy like software
- •You need full control over your runtime environment and dependency versions
- •You want isolated execution where the platform never accesses your source code
- •You want free live trading execution through the open-source Trading Gateway with no per-algorithm fees
Where QuantConnect differs
- •QuantConnect covers more asset classes today — Tektii is expanding beyond forex
- •The LEAN engine is open source if self-hosting and source-level control are requirements
- •QuantConnect includes built-in indicators and research notebooks — Tektii lets you bring any library instead
- •If you are already invested in the LEAN ecosystem, migrating has a cost
- •QuantConnect has a larger community today — Tektii is in early access with a fast-growing user base
Frequently asked questions
Is Tektii a good QuantConnect alternative?
Tektii is built for traders who want language freedom, Docker-native workflows, CI/CD pipelines, and portable strategies with no vendor lock-in. If you have felt constrained by LEAN's C#/Python requirement, or want your strategies to deploy like production software rather than framework-specific code, Tektii solves those problems directly. QuantConnect covers more asset classes today, though Tektii's coverage is expanding rapidly. For traders who prioritise modern DevOps workflows and language choice, Tektii is the stronger platform.
Can I migrate from QuantConnect to Tektii?
Since Tektii uses Docker containers, you can package your strategy logic in any language. If your QuantConnect strategy is in Python, you'd rewrite the LEAN-specific parts (data subscriptions, order management) to use Tektii's WebSocket and REST APIs, while keeping your core signal logic. The strategy itself becomes a portable Docker image rather than framework-specific code.
How does the execution model differ between the two platforms?
Both platforms aim for backtest-to-live consistency. QuantConnect runs strategies inside the LEAN process using the LEAN API. Tektii strategies run in isolated Docker containers that communicate via WebSocket and REST. The backtest engine and the open-source Trading Gateway share the same API protocol — write once, run in simulation or live with zero code changes. Live execution is handled by the free, open-source Trading Gateway, not the paid platform.
What about strategy privacy and intellectual property?
Tektii runs your strategy in an isolated Docker container — the platform executes your container without accessing the source code inside it. QuantConnect provides encryption at rest, IP ownership protections, and restricted staff access. Both platforms take strategy privacy seriously. QuantConnect also offers a local platform option where your code never leaves your machine.
How does data coverage compare?
QuantConnect covers more asset classes today, including equities, options, futures, forex, crypto, and alternative data. Tektii currently provides tick-level forex data, with equities and crypto on the near-term roadmap. Where Tektii differentiates on data is granularity: tick-level simulation gives you more accurate fill and slippage modelling than bar-level data, regardless of which assets you are trading. As Tektii's asset coverage expands, you get both breadth and depth.
