SiYuan vs Obsidian

I hope my question isn't bothering anyone. I see that SiYuan is an excellent tool as a second brain, and I like it more than Obsidian, but I still have my doubts about whether it's worth migrating. Since I'm new to both tools, I'd like someone to explain the differences and advantages between them so I can make my decision.

    Here we can learn from each other how to use SiYuan, give feedback and suggestions, and build SiYuan together.

      • Open source: Unlike Obsidian, which is closed source, Siyuan's source is open. This gives a lot of benefits; some of them will be cited below
      • Performance: Siyuan can handle millions of documents; Obsidian lags badly at the 280,000+ notes mark
      • One-time payment for Sync & Versatility of choice: Obsidian offers only subscription-based sync; Siyuan offers one-time payment and also one-time payment for a subscription plan for limited seats
      • Sustainability: Due to its small team, location, the enormous edge that Siyuan offers, and its rapid international adoption, Siyuan's sustainability looks stable.
      • Posteriority & Aging: Siyuan's technical stack is future-proof, its usage of Go for kernel and pure HTML/CSS/JS for interface are good foundation for solid aging.
      • Intentionality: Attention to details, precision, well-thought-out design decisions, focus on the right things...ect
      • Experience & Wisdom: B3log dev team cumulated 20+ years of experience around markdown, editing and publishing. The remarkable adoption of Siyuan didn't come overnight, its the fruit of long years of making the right decisions.

      I have been using Siyuan for a long while. Obsidian I have used far less. I do find Siyuan superior and havent regretted or had any desire to switch back to obsidian. If you do commit to migration to siyuan from obsidian, obviously there isnt an ideal back and forth migration (between siy vs obs) that retains all document structures, backlinks perfectly intact last I tested 6 months back, mainly because the syntaxes differ (and features differ) between the two apps for creating backlinks. I have seen some third-party tools specific to migration, and since 6 months there might be better solutions I havent figured out

      Siyuan Excels in:

      • editing: where Obsidian can still be a little quirky, rather Siyuan has flawless consistency editing paragraphs, code block, lists, embedded blocks and not to forget moving any block types around. Moving blocks and nesting blocks also feels superior in Siyuan
      • Backup/restore: Siyuan can backup of entire workspace, partial documents, migrate to new workspaces while retaining prior structures and context flawlessly. I havent had any issues starting anew, creating temporary workspaces. I have less understanding how Obsidian deals with deep backup/restore that much, but Siyuan wont leave you hanging or yurning obsidian.

      There is more to be said and compare, but basically, Siyuan never left me hanging or desiring a switch. The core features of siyuan (some mentioned above) as stable PKM were superior, where Obsidian (and switching between edit view vs reading view) seems more quirky.

      I haven't got a definitive pros and cons, but you could probably get that using ChatGPT or Gemini. I used Obsidian for a long while, but in the end I didn't like paying a monthly subscription to sync my notes, and couldn't get other Obsidian options to work cleanly. I also became annoyed with the number of plugins I had to use and maintain to make things work how I wanted.

      Obsidian is a great tool and has huge community engagement, but I've found SiYuan a more complete PKM implementation which looks great and does everything I need, and I still retain control of my data.

      I use Cloudflare R2 (S3 storage) for sync as it has a generous free tier.
