It uses the MIT license but the datasets adhere to Matterport3D terms. [AliceVision](https://alicevision.org) reports 3.5k GitHub stars, 879 forks, and 42 open issues, last pushed Jul 30, 2026. [VLN-CE](https://jacobkrantz.github.io/vlnce/) has 844 stars, 90 forks, and 29 open issues, last pushed Jan 7, 2025.

It uses the MIT license but the datasets adhere to Matterport3D terms. ## Choose when ### Choose AliceVision if… - AliceVision is primarily C++; VLN-CE is Python. - License: AliceVision is Other, VLN-CE is MIT. - Tags unique to AliceVision: 3d-computer-vision, 3d-reconstruction, alicevision, camera-tracking. - For C++ programmers working on projects that require precise 3D modeling using stereo vision techniques ### Choose VLN-CE if… - VLN-CE is primarily Python; AliceVision is C++. - License: VLN-CE is MIT, AliceVision is Other. - Tags unique to VLN-CE: computer-vision, deep-learning, python, research. - Also covers Model Training. - When aiming to advance robotics navigation by training models on vision-language tasks with habitat-sim. ## When NOT to use AliceVision - If your project requires a high-level programming interface less involved with low-level coding in C++ - For users who prefer a fully integrated software solution over a framework that might require custom integration ## When NOT to use VLN-CE - Avoid if your project needs fully open datasets, as some VLN-CE components are restricted by Matterport3D license terms. - Steer clear if you prefer tools with built-in support for environments other than those within the Habitat simulation framework. ## Common questions ### What is the difference between AliceVision and VLN-CE? AliceVision: 3D Computer Vision Framework. VLN-CE: Vision-and-Language Navigation in Continuous Environments using Habitat. See the comparison table for live GitHub stats and shared categories. ### When should I choose AliceVision over VLN-CE? Choose AliceVision over VLN-CE when AliceVision is primarily C++; VLN-CE is Python; License: AliceVision is Other, VLN-CE is MIT; Tags unique to AliceVision: 3d-computer-vision, 3d-reconstruction, alicevision, camera-tracking; For C++ programmers working on projects that require precise 3D modeling using stereo vision techniques. ### When should I choose VLN-CE over AliceVision? Choose VLN-CE over AliceVision when VLN-CE is primarily Python; AliceVision is C++; License: VLN-CE is MIT, AliceVision is Other; Tags unique to VLN-CE: computer-vision, deep-learning, python, research; Also covers Model Training; When aiming to advance robotics navigation by training models on vision-language tasks with habitat-sim. ### When should I avoid AliceVision? If your project requires a high-level programming interface less involved with low-level coding in C++ For users who prefer a fully integrated software solution over a framework that might require custom integration ### When should I avoid VLN-CE? Avoid if your project needs fully open datasets, as some VLN-CE components are restricted by Matterport3D license terms. Steer clear if you prefer tools with built-in support for environments other than those within the Habitat simulation framework. ### Is AliceVision or VLN-CE more popular on GitHub? AliceVision has more GitHub stars (3,462 vs 844). Stars measure visibility, not whether either tool fits your constraints. ### Are AliceVision and VLN-CE open source? Yes - both are open-source projects on GitHub (AliceVision: Other, VLN-CE: MIT). ### Where can I find alternatives to AliceVision or VLN-CE? GraphCanon lists graph-backed alternatives at [AliceVision alternatives](/tools/alicevision-alicevision/alternatives) and [VLN-CE alternatives](/tools/jacobkrantz-vln-ce/alternatives) ([AliceVision markdown twin](/tools/alicevision-alicevision/alternatives.md), [VLN-CE markdown twin](/tools/jacobkrantz-vln-ce/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/alicevision-alicevision-vs-jacobkrantz-vln-ce.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, AliceVision or VLN-CE? AliceVision: Very active. VLN-CE: Dormant. 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 AliceVision and VLN-CE? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [AliceVision trust report](/tools/alicevision-alicevision/trust); [VLN-CE trust report](/tools/jacobkrantz-vln-ce/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=alicevision-alicevision`](/api/graphcanon/graph?tool=alicevision-alicevision) - 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/_
