Problems We Solve
Performance at Scale
Notion becomes noticeably slow with large workspaces. Hyperclast uses viewport-based rendering - only visible content loads. 10 pages or 10,000, same speed.
Vendor Lock-in
Notion's proprietary block format makes full export difficult. Your data lives in formats you can't easily use elsewhere. Hyperclast gives you standard formats you own.
API Limitations
Notion's API has strict rate limits and doesn't support all block types. Hyperclast offers a full REST API with webhooks for real integrations.
Closed Source
You can't inspect how Notion works, can't self-host, can't modify. Hyperclast is open source - audit the code, self-host if you need to.
When to Choose Each
Choose Notion if...
- You need advanced databases with relations and rollups
- You want extensive templates and a large community ecosystem
- Your workspace is small and speed isn't critical
- You prefer visual, drag-and-drop page building
Choose Hyperclast if...
- Speed matters - you have large workspaces or hate waiting
- You value data ownership and standard export formats
- You need self-hosting or want to audit the code
- You want a full API and webhooks for integrations
- You prefer text-first, distraction-free writing
Frequently Asked Questions
Can I import my Notion workspace?
Yes! Export your Notion workspace as Markdown and import directly into Hyperclast. Most content transfers cleanly, though some Notion-specific features like databases won't have exact equivalents.
How is Hyperclast faster than Notion?
Hyperclast uses viewport-based rendering and CRDTs for real-time sync. We only load what's visible on screen, so document size doesn't affect performance. Notion loads more data upfront, which causes slowdowns with large workspaces.
Does Hyperclast have databases like Notion?
Hyperclast focuses on text-first knowledge management. If you heavily rely on Notion's database features with relations and rollups, Notion might be a better fit. We prioritize speed and simplicity over complex data structures.
Is Hyperclast really open source?
Yes! We use the Elastic License. You can view the source code, self-host for your team, and audit how everything works. The license protects against competitors reselling the product while keeping it free for users.
