See the comparison table for live GitHub stats and shared categories. ### When should I choose holodeck over habitat-sim? Choose holodeck over habitat-sim when holodeck is primarily Python; habitat-sim is C++; Tags unique to holodeck: drones, reinforcement-learning, unreal-engine; Also covers Model Training; - When you need to simulate complex robotics scenes in high fidelity that mirror real-world scenarios accurately. ### When should I choose habitat-sim over holodeck? Choose habitat-sim over holodeck when habitat-sim is primarily C++; holodeck is Python; Requirements: Installation can be done via Conda, pip, Docker, or building from source. Building from source requires C++ development environment setup.; Tags unique to habitat-sim: cplusplus, sim2real; When you require high performance simulation of 3D environments for research in embodied artificial intelligence. ### When should I avoid 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 should I avoid habitat-sim? If your project does not require the performance characteristics that Habitat-Sim provides for embodied AI research; a less specialized tool might be sufficient or more user-friendly When you have limited development resources since building from source requires an understanding of C++ and handling potential build issues could divert significant effort ### Is holodeck or habitat-sim more popular on GitHub? habitat-sim has more GitHub stars (3,765 vs 597). Stars measure visibility, not whether either tool fits your constraints. ### Are holodeck and habitat-sim open source? Yes - both are open-source projects on GitHub (holodeck: MIT, habitat-sim: MIT). ### Where can I find alternatives to holodeck or habitat-sim? GraphCanon lists graph-backed alternatives at [holodeck alternatives](/tools/byu-pccl-holodeck/alternatives) and [habitat-sim alternatives](/tools/facebookresearch-habitat-sim/alternatives) ([holodeck markdown twin](/tools/byu-pccl-holodeck/alternatives.md), [habitat-sim markdown twin](/tools/facebookresearch-habitat-sim/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/byu-pccl-holodeck-vs-facebookresearch-habitat-sim.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, holodeck or habitat-sim? holodeck: Dormant. habitat-sim: Active. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for holodeck and habitat-sim? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [holodeck trust report](/tools/byu-pccl-holodeck/trust); [habitat-sim trust report](/tools/facebookresearch-habitat-sim/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=byu-pccl-holodeck`](/api/graphcanon/graph?tool=byu-pccl-holodeck) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
