How the score of 48 was calculated
| Factor | Share of maximum | Points |
|---|---|---|
| NoveltyRubric level 2/4 (Moderate). Heuristic (automated): first published 53 days ago. | 7.5/15 | |
| Technical significanceRubric level 3/4 (High). AI-assisted (openai/gpt-oss-20b), pending human review: Moli combines a full web runtime with on‑demand visual rendering in a single Rust binary, eliminating the need for separate browser drivers and reducing resource overhead. Evidence: “Full-featured — real JavaScript, DOM, CSS, networking, storage, layout, screenshots, and standard automation protocols, all integrated into one headless browser.” | 11.3/15 | |
| Developer relevanceRubric level 3/4 (High). AI-assisted (openai/gpt-oss-20b), pending human review: Provides a lightweight, fast, and unified automation tool that can replace heavier browsers like Chrome or Firefox in agent workloads. Evidence: “Fast — most automation requests never need visual rendering, so structure-first operations skip layout and paint entirely.” | 11.3/15 | |
| Adoption velocityIndependent integrations: unknown (0 pts). GitHub stars: 81.5 per day since creation; full marks at 1000/day, log-scaled (3.2/5). | 3.2/10 | |
| Community momentumFewer than three periods of activity data, or no baseline activity to compare against. | 0/10 | |
| Source credibilityPrimary source present; mean source-tier weight 1.00 (primary 1.0, secondary 0.7, community 0.35). | 10/10 | |
| Cross-source confirmationNo independent publisher has confirmed this yet. | 0/10 | |
| Evidence strengthMet 2/4: primary source ✓, runnable artifact (code, weights or package) ✓, reproducible or independent benchmark ?, technical documentation or paper ✗. 1 unknown (scored 0). | 5/10 | |
