Five challengers, one crown, and a category error
An XDA writer spent time with five open-source Obsidian alternatives — Logseq, Joplin, TriliumNext, SiYuan, and AppFlowy — and walked away with a clear winner: AppFlowy, won on polish, built-in databases, Kanban boards, and AI features that arrive without a plugin spree. It’s a fair verdict, and I don’t argue with the testing. I argue with the framing — because I don’t think the shootout proves AppFlowy is the best Obsidian alternative. It proves the tester was shopping for Notion.
You don’t switch apps; you hire them for a job
People leave Obsidian for roughly three reasons, and they’re completely different jobs:
- Plugin fatigue. You’ve spent twenty hours assembling a workspace out of community plugins and you’re tired of maintaining a cathedral.
- A Notion-shaped hole. You want databases, boards, and timelines — a project workspace — and you’re tired of building them out of plugins.
- Sync sovereignty. You want your notes on hardware you own, with no vendor in the loop, and Obsidian’s sync options feel like someone else’s product decision.
AppFlowy won the test because the test was job #2. It’s a genuinely good Notion-alike: block editor, nested pages, grid/Kanban/timeline views, charts, slash commands, AI assistance, Google Drive embeds. If your complaint about Obsidian was “I’m using it to run projects and it fights me,” AppFlowy is the correct answer and the polish gap the writer found in TriliumNext and SiYuan is real.
But if your complaint was job #1 or job #3, the winner’s podium looks nothing like that.
The field, matched to the job it’s actually good at
- Joplin is the sync-sovereignty answer that bores people into overlooking it. Markdown notes, end-to-end encrypted sync, and — the part a homelab owner cares about — it syncs over plain WebDAV, which means the Nextcloud you already run is your note backend. Nothing new to host.
- Logseq is an outliner with a journal-first habit loop. The “learning curve” the review hit isn’t a defect; it’s a different paradigm wearing Obsidian’s clothes. Hire it for thinking in outlines and backlinks, not for documents.
- TriliumNext is the team-wiki engine: deep hierarchy, scriptable, self-hostable server. Overwhelming UI, yes — because it’s aimed at people building a knowledge base, not a journal.
- SiYuan brings block references and real databases in one package, with a self-hosted server option. Strong feature set, rougher edges, especially on macOS.
- AppFlowy is the workspace: the most Notion-shaped of the five, and — the detail that matters here — its cloud has a self-hostable server, so a small team can run the whole thing on one Docker host.
The open-source nuance everyone skips
AppFlowy being open source is a real advantage over Notion — you can inspect it, fork it, and run the server yourself, which for a 3–10 person business that doesn’t want a vendor reading its ops notes is a legitimate appliance: one box, no per-seat SaaS, data at rest on your iron. That’s the deployment where I’d actually recommend it without hedging.
But “open source” is not “files you own.” Obsidian’s data model is a folder of plain Markdown — exit cost zero, toolchain grep, git, and everything else forever. AppFlowy’s data model is an app-shaped store that its server understands. You’re not locked in the way Notion locks you in, but you’re also not one tar command away from your own notes. If the job is notes, the folder still wins. If the job is running projects with other people, built-in databases beat a folder, and AppFlowy has earned its win.
The test to run before you switch anything
Write down the job in one sentence before you migrate a single note. Most “Obsidian fatigue” I see — including the plugin sprawl the original article opens with — is really a plugin cathedral problem, and the cure is deleting plugins, not changing apps. Deleting is reversible, free, and takes an evening.
But if the sentence you wrote down starts with “I need to track…” and ends with a board, a timeline, or a team — that’s not fatigue. That’s a hiring mistake: you’ve been employing a note app to do a workspace’s job. Then AppFlowy isn’t the alternative that won a shootout; it’s the tool you should have hired in the first place. And running its server next to your other self-hosted services is exactly where a setup like that belongs.
