See the comparison table for live GitHub stats and shared categories. ### When should I choose habitat-lab over habitat-sim? Choose habitat-lab over habitat-sim when habitat-lab is primarily Python; habitat-sim is C++; Requirements: Min 8 GB RAM; Requires Docker; Python >=3.9 is required along with cmake>=3.14 for installation; For users working on machines equipped with NVIDIA GPUs, nvidia-docker installation is necessary to run the provided Docker containers; Tags unique to habitat-lab: deep-learning, reinforcement-learning, research; Also covers AI Agents; habitat-lab ships Docker support for self-hosted deployment; Use Habitat-Lab when your project requires the simulation of complex environments for embodied AI tasks, such as navigation and interaction with objects. ### When should I choose habitat-sim over habitat-lab? Choose habitat-sim over habitat-lab when habitat-sim is primarily C++; habitat-lab 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; When you require high performance simulation of 3D environments for research in embodied artificial intelligence. ### When should I avoid habitat-lab? Avoid Habitat-Lab if the computational resources required for running the simulations exceed what is available or feasible in terms of cost Do not use Habitat-Lab when the project is solely focused on real-world data and does not necessitate virtual training environments, as setting up such a library might add unnecessary complexity ### 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 habitat-lab or habitat-sim more popular on GitHub? habitat-sim has more GitHub stars (3,765 vs 3,082). Stars measure visibility, not whether either tool fits your constraints. ### Are habitat-lab and habitat-sim open source? Yes - both are open-source projects on GitHub (habitat-lab: MIT, habitat-sim: MIT). ### Where can I find alternatives to habitat-lab or habitat-sim? GraphCanon lists graph-backed alternatives at [habitat-lab alternatives](/tools/facebookresearch-habitat-lab/alternatives) and [habitat-sim alternatives](/tools/facebookresearch-habitat-sim/alternatives) ([habitat-lab markdown twin](/tools/facebookresearch-habitat-lab/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/facebookresearch-habitat-lab-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, habitat-lab or habitat-sim? habitat-lab: Steady. 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 habitat-lab and habitat-sim? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [habitat-lab trust report](/tools/facebookresearch-habitat-lab/trust); [habitat-sim trust report](/tools/facebookresearch-habitat-sim/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=facebookresearch-habitat-lab`](/api/graphcanon/graph?tool=facebookresearch-habitat-lab) - 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/_
