[holodeck](https://holodeck.cs.byu.edu) reports 597 GitHub stars, 42 forks, and 52 open issues, last pushed Feb 19, 2022. [LazyLLM](https://docs.lazyllm.ai/) has 3.9k stars, 404 forks, and 41 open issues, last pushed Aug 7, 2026. Figures are from public GitHub metadata via [holodeck's repository](https://github.com/BYU-PCCL/holodeck) and [LazyLLM's repository](https://github.com/LazyAGI/LazyLLM). | | [holodeck](/tools/byu-pccl-holodeck.md) | [LazyLLM](/tools/lazyagi-lazyllm.md) | | --- | --- | --- | | Tagline | High Fidelity Simulator for Reinforcement Learning and Robotics Research | Easiest and laziest way for building multi-agent LLMs applications. | | Stars | 597 | 3,866 | | Forks | 42 | 404 | | Open issues | 52 | 41 | | Language | Python | Python | | Adopt for | Holodeck is a high-fidelity simulator for reinforcement learning and robotics research in Python using Unreal Engine, suited for creating detailed simulated environments. | Critical facts for LazyLLM | | Persona | - | - | | Runtime | - | - | | License | MIT | Apache-2.0 | | Categories | Computer Vision, Model Training | AI Agents, Model Training | ## Trust and health _Sourced signals - not a safety guarantee.

No Docker required, but a Python environment is necessary. - **Adopt for:** Critical facts for LazyLLM ## Choose when ### Choose holodeck if… - License: holodeck is MIT, LazyLLM is Apache-2.0. - Tags unique to holodeck: ai, computer-vision, drones, reinforcement-learning. - Also covers Computer Vision. - - When you need to simulate complex robotics scenes in high fidelity that mirror real-world scenarios accurately ### Choose LazyLLM if… - License: LazyLLM is Apache-2.0, holodeck is MIT. - Pricing: LazyLLM is open-source under the Apache-2.0 license, making it free to use for both personal and commercial projects.. - Requirements: Min 8 GB RAM; Installation can be done via pip or from source. No Docker required, but a Python environment is necessary.. - Tags unique to LazyLLM: agents, ai-agent, deep-learning, framework. - Also covers AI Agents. - - When you need a highly user-friendly framework specifically designed for building multi-agent LLM applications, emphasizing simplicity and streamlined installation. ## When NOT to use holodeck - - If your project is limited to simpler scenarios where less detailed simulations are acceptable for training reinforcement learning models - - For projects with constraints on computing resources since Unreal Engine can be demanding and this limits its use in resource-constrained environments. ## When NOT to use LazyLLM - - Avoid if you require extensive customization options or a more complex framework; LazyLLM's focus on being the 'laziest' way may mean it lacks advanced or specialized features found in other tools. - - If you are working with non-Python environments, as LazyLLM is specifically language-oriented towards Python. Users needing cross-language support might not find LazyLLM suitable. ## Common questions ### What is the difference between holodeck and LazyLLM? holodeck: High Fidelity Simulator for Reinforcement Learning and Robotics Research.
