nebula vs Agentero
nebula has 12,464 GitHub stars, 1,342 forks, 678 open issues and last shipped 2 months ago. Agentero has 1,070 stars, 83 forks, 38 open issues and last shipped 2 days ago. nebula leads on adoption by 1,065% (12,464 vs 1,070 stars). nebula is written in C++ under Apache-2.0; Agentero is written in TypeScript under MIT. nebula has attracted 11% as many forks as stars, Agentero 8%. Agentero was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (knowledge-base), so they are genuine substitutes rather than adjacent tools.
Two open source projects, one decision. Both are free and self-hostable — the differences are community size, license terms, language stack and release pace.

About Agentero
为人与 Agent 协作而生的一站式科研工作台 保留人类舒适的 PDF 阅读习惯，为模型提供纯净的结构化上下文；文献、笔记与交互记录统一沉淀于本地。 中文 English 如果本项目对你有帮助，请在右上角 给个 star 吧！ 背景与设计初衷 Zotero 是学术管理领域非常优秀的软件。它功能成熟、生态稳定，帮助许多科研人员建立了最初的文献归档体系。 但在当下日常科研与深度使用各类 Agent 时，传统的文献工具链暴露出一些断点： 上下文严重分散 ：论文存储在 Zotero，笔记记在 Obsidian，与模型的推导和分析留在各个网页对话框中。三者数据彼此隔离，当需要 Agent 结合某篇具体论文与历史笔记进行深入推导时，用户必须反复手动复制粘贴。 文献格式对模型不友好 ：人类习惯阅读排版良好的 PDF 文件；但对于模型而言，直接解析双栏排版、跨页表格、复杂数学公式和交叉引用的成本极高，极易产生识别错误与幻觉。结构化 Markdown 与 LaTeX 才是模型容易准确理解的格式。 维护成本较高 ：AI 伴读、全文翻译、笔记同步等高频需求，往往需要安装和调试多个社区插件，配置门槛高且在版本升级时容易出现兼容性问题。 批量自动化能力有限 ：通过 Deep Research 或自动化检索工具发现的大量文献，目前仍需人工在浏览器中逐篇点击保存，难以顺畅衔接批量研究流。 Agentero 并非旨在替代…
