utopia vs MimirQ
utopia has 8,667 GitHub stars, 1,185 forks, 27 open issues and last shipped yesterday. MimirQ has 585 stars, 101 forks, 4 open issues and last shipped 2 days ago. utopia leads on adoption by 1,382% (8,667 vs 585 stars). utopia is written in Rust under Apache-2.0; MimirQ is written in Python under Apache-2.0. utopia has attracted 14% as many forks as stars, MimirQ 17%. utopia was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 5 topic tags (graphrag, knowledge-base, knowledge-graph, llm), 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 utopia
Utopia Philosophy · Quick start · Features · Roadmap The enterprise world model built by DeepLethe. It is the first open substrate for knowledge engineering that learns passively and governs itself. Where a knowledge graph or a vector store works to hold present knowledge, Utopia puts time awareness and ontology in the base layer: the knowledge system evolves as material arrives, and conflict detection, reasoning and decision making all run against that ontology. It deploys offline, so a company can stand up a knowledge foundation, a decision core its agents can trust, and a compliance audit trail on hardware it…

About MimirQ
MimirQ 可观察、可替换、可回归的企业 RAG 基础设施 中文优先 · 从文档解析到证据引用，每一步都能检查输入、输出与版本 项目定位 · 产品界面 · 快速开始 · 平台对比 · 800 题实测 · 完整文档 简体中文 · English · 日本語 · 한국어 为什么做 MimirQ 企业知识库真正难的，不是把文档向量化，而是让错误可定位、策略可替换、质量可回归。 MimirQ 起源于真实的政务知识库交付。回答出错时，团队需要快速判断问题究竟来自解析、治理、切块、召回、重排，还是生成偏离引用。把整条链路藏在一个“上传并开始问答”的按钮后面，原型很快，长期交付却难以估算、验收和治理。 一条可控的企业知识流水线 数据评估 → 场景化解析 → 清洗治理 → 业务切块 → 向量 / 全文索引 → 混合召回 → 重排与引用 → Golden 回归 真实项目应先抽样评估数据，再按材料选择解析器：复杂版式或扫描件可比较 MinerU / DeepDoc，公式、表格与版面结构密集的资料可评估 Docling，数字原生 Office 或纯文本可从 MarkItDown 等轻量路径开始。高风险资料仍需人工校验。 解析结果经脚本、规则 DSL 或插件治理后，再按标题、章节、业务记录或父子关系切块，而不是统一套用固定长度和重叠窗口。索引层可使用 Milvus 等向量库，并组合 BM25、向量检索与重排；上层应用可以是…
