How to Decide
Obsidian is a local‑first, markdown‑based knowledge base used by individual researchers, writers, and developers. The alternatives split into a few clear camps: logseq leans on open‑source, hierarchical note‑taking with a free tier; Trilium emphasizes self‑hosted deployment and powerful full‑text search; Notion focuses on cloud SaaS with relational databases and an API; Marktext offers a minimalist markdown editor with live preview and multi‑platform desktop apps; Foam centers on a graph‑database backend with extensible plugins and an available API.
When choosing a replacement, consider where your data lives (local markdown files versus cloud storage), how you organize and retrieve information (graph links, hierarchical tags, or relational tables), the extensibility model you need (plugin ecosystems versus built‑in features), the deployment platform (desktop‑only versus SaaS), and the pricing structure (free/open‑source versus paid sync or team plans).
