Scope
Metadata and repository facts recorded from the official GitHub API on 2026-08-14. Sensor assumptions are recorded from official README statements. Flight-test behavior, benchmark numbers and certification are deliberately not compared because the indexed sources do not provide field-level evidence.

This comparison does not rank the projects. Field values come only from the linked sources; unrecorded values remain Unknown.
Verification sequence
- Open each repository page and confirm license and maintenance from the official API.
- Run each system on its officially documented dataset and record the version.
- Verify the sensor setup of your vehicle against the recorded assumptions before choosing.
Limitations
- This comparison records repository-level facts only.
- It does not certify flight-safety behavior or hardware compatibility of any combination.
- Unknown cell values are kept as Unknown; absence of a value is not a judgment.
