[carla](http://carla.org) reports 14k GitHub stars, 4.6k forks, and 1.2k open issues, last pushed Jul 10, 2026. [text2vec](https://pypi.org/project/text2vec/) has 5.0k stars, 428 forks, and 7 open issues, last pushed Feb 14, 2026. Figures are from public GitHub metadata via [carla's repository](https://github.com/carla-simulator/carla) and [text2vec's repository](https://github.com/shibing624/text2vec). | | [carla](/tools/carla-simulator-carla.md) | [text2vec](/tools/shibing624-text2vec.md) | | --- | --- | --- | | Tagline | Open-source simulator for autonomous driving research. | 文本向量表征工具，实现多种文本表征和相似度计算模型 | | Stars | 14,161 | 4,971 | | Forks | 4,626 | 428 | | Open issues | 1,185 | 7 | | Language | C++ | Python | | Adopt for | - | - | | Persona | - | - | | Runtime | - | - | | License | MIT | Apache-2.0 | | Categories | AI Agents, Model Training, Vector Databases | Data & Retrieval, Model Training | ## Trust and health _Sourced signals - not a safety guarantee.

Validate activity before betting a new project on text2vec. - Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough. - Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ## Common questions ### What is the difference between carla and text2vec? carla: Open-source simulator for autonomous driving research.. text2vec: 文本向量表征工具，实现多种文本表征和相似度计算模型. See the comparison table for live GitHub stats and shared categories. ### When should I choose carla over text2vec?

Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. ### When should I avoid text2vec? Last GitHub push was 147 days ago (slowing maintenance, Feb 14, 2026). Validate activity before betting a new project on text2vec. Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough. Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ### Is carla or text2vec more popular on GitHub? carla has more GitHub stars (14,161 vs 4,971). Stars measure visibility, not whether either tool fits your constraints. ### Are carla and text2vec open source? Yes - both are open-source projects on GitHub (carla: MIT, text2vec: Apache-2.0). ### Where can I find alternatives to carla or text2vec? GraphCanon lists graph-backed alternatives at [carla alternatives](/tools/carla-simulator-carla/alternatives) and [text2vec alternatives](/tools/shibing624-text2vec/alternatives) ([carla markdown twin](/tools/carla-simulator-carla/alternatives.md), [text2vec markdown twin](/tools/shibing624-text2vec/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/carla-simulator-carla-vs-shibing624-text2vec.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, carla or text2vec? carla: Very active. text2vec: Slowing. 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 carla and text2vec? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [carla trust report](/tools/carla-simulator-carla/trust); [text2vec trust report](/tools/shibing624-text2vec/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=carla-simulator-carla`](/api/graphcanon/graph?tool=carla-simulator-carla) - 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/_
