AFFiNE vs BookStack

The one question that decides this

The real split is whether you want a Notion/Miro-shaped workspace for planning, sorting, and creating, or a self-hosted knowledge base that behaves more like a sober internal wiki. AFFiNE’s own line is “There can be more than Notion and Miro,” and its GitHub description says it is a “next-gen knowledge base” that brings “planning, sorting and creating all together.” BookStack is much narrower on purpose: “A simple, self-hosted, easy-to-use platform for organising and storing information.” If you want a flexible canvas-ish productivity system, AFFiNE is the more obvious bet; if you want durable documentation without the productivity-app perfume, BookStack is the cleaner fit.

What each one is actually trying to be

AFFiNE: Notion plus Miro energy, open-source edition

AFFiNE is trying to be a broad workspace, not just a wiki. The project’s tagline, “There can be more than Notion and Miro,” is not subtle. It is positioning itself as a place where notes, planning, knowledge work, and visual creation can live together instead of being split across a docs app and a whiteboard app.

That ambition is the appeal, and also the thing to watch. The GitHub description calls AFFiNE “Privacy first, open-source, customizable and ready to use,” which is exactly the pitch people want to hear after getting tired of SaaS workspaces that slowly become billing events with a sidebar. But broad workspace tools can also become feature soup fast. AFFiNE is the better pick if you actually want the extra surface area: planning, sorting, creation, and a Notion/Miro replacement story in one product.

BookStack: A wiki that knows it is a wiki

BookStack is not trying to be a second operating system for your company. Its tagline is plain: “A simple, self-hosted, easy-to-use platform for organising and storing information.” That is the whole vibe. It replaces Notion and Confluence, but it does so from the documentation side, not the infinite-canvas-productivity-dashboard side.

This is a strength if your problem is “our docs are a mess,” not “we need a beautiful all-purpose workspace where every team invents its own semi-private taxonomy.” BookStack’s pitch is less glamorous, which in wiki software is often a compliment. A boring place to put organized information beats an over-designed productivity shrine when the job is onboarding notes, internal manuals, policies, runbooks, and the kind of pages people need to find six months from now.

Head-to-head: the metrics

AFFiNE’s GitHub repo, toeverything/AFFiNE, shows 70,662 stars, 5,072 forks, 674 open issues, license listed as NOASSERTION, and a last push date of 2026-07-21. It is written primarily in TypeScript. Those are large numbers, especially the stars and forks, and they line up with a project that is chasing a big, popular category: Notion and Miro alternatives are catnip for developers who want the interface without the SaaS leash.

BookStack’s GitHub repo, BookStackApp/BookStack, shows 18,926 stars, 2,411 forks, 1 open issue, license MIT, and a last push date of 2026-07-21. It is written primarily in PHP. Its GitHub description says “NOW MANAGED ON CODEBERG,” which matters because GitHub is not necessarily the whole operational picture for the project anymore. Still, the GitHub numbers give a useful public snapshot: smaller star count than AFFiNE, a permissive MIT license, and a very different issue count.

The metrics say AFFiNE has much louder GitHub gravity. More stars, more forks, and a bigger public footprint. That does not automatically mean it is the better tool; it means more people have noticed it, starred it, forked it, or are at least watching the category. Notion-shaped tools attract drive-by attention in a way plain documentation software rarely does.

The metrics also say BookStack is not some abandoned wiki sitting in a basement with a PHP version warning taped to the door. The last push date is also 2026-07-21, the license is clear MIT, and the project has a long-standing identity. The “1 open issue” number should be read carefully because the repo description says it is now managed on Codeberg. It is a signal, not a full health report.

What the metrics do not tell us is whether AFFiNE’s wider ambition will fit your team, or whether BookStack’s simpler model will feel refreshing or restrictive. Stars do not measure documentation quality. Forks do not measure whether your non-technical coworkers will use the thing. Open issues do not tell the whole maintenance story when a project points development activity elsewhere. Metrics are useful for smell tests; they are not product strategy.

Self-hosting

AFFiNE supports self-host and official-cloud hosting options. Its deploy difficulty is listed as 3 out of 5, which puts it in the middle: not “click a button and forget it,” but also not necessarily a weekend-eating infrastructure ritual. The official SaaS price is listed as $6.75 monthly, so AFFiNE gives you both routes: use their cloud if you want the managed path, or self-host if control is the point.

BookStack supports self-host only in the provided data. Its deploy difficulty is listed as 2 out of 5, which matches the general shape of the project: focused, practical, and less ambitious in scope than a full workspace trying to replace multiple SaaS categories. There is no official SaaS monthly price provided here, so there is no honest number to compare against AFFiNE’s $6.75. If you want a managed vendor path from the project itself, the provided hosting data does not show one.

Community signals

AFFiNE has 2 Hacker News mentions in the last 90 days in the provided data, but the listed top HN story is “Affine transformations,” posted by signa11 on 2018-01-10, with 82 points and 19 comments. That is about affine transformations, not clearly about the AFFiNE product. So the honest read is: there is HN data present, but this particular top story is not a meaningful product signal for AFFiNE. Treating it like community validation for the app would be classic SEO slop.

The provided Reddit top post for AFFiNE is also not useful as a product signal. It is titled “Morality of giving every single person a permanent symbol of their 'destiny' the moment they do something they're 'meant to do' the rest of their life?”, from r/MoralityScaling, with 15,689 upvotes and 409 comments. That is not evidence that people are discussing AFFiNE as a Notion alternative. It is just data with a matching-looking string somewhere in the machinery.

BookStack’s HN signal is much cleaner. The provided top story is “Show HN: BookStack – An open source wiki platform and alternative to Confluence,” posted by ssddanbrown on 2022-01-08, with 562 points and 198 comments. That is directly about the product and directly about the category. It does not prove BookStack is right for you, but it does show the project has had real attention from the kind of audience that cares about self-hosted software and Confluence alternatives.

BookStack’s provided Reddit top post is less useful. It is titled “I (sort of) discovered a relationship between two areas of mathematics by accident.” from r/math, with 3,397 upvotes and 148 comments. That is not a BookStack product discussion. As with AFFiNE’s Reddit item, it should not be laundered into fake community sentiment.

What we'd do

Pick AFFiNE if you want an open-source productivity workspace that reaches toward both Notion and Miro, and you are comfortable with a broader, more ambitious tool. Pick BookStack if your real need is organized internal knowledge, docs, and wiki pages without turning the whole company into amateur workspace architects. AFFiNE wins for flexible planning and creation; BookStack wins for boring, durable documentation. And boring is not an insult here.
