Looking for working bidirectional sync solution between Notion and Airtable - what's your experience?

Hi everyone! I’m a freelance automation specialist who has been working with Airtable for about two years now. I’ve created some complex databases with multiple integrations and workflow automations for my clients.

Recently I started testing Notion and found it handles certain scenarios really well. One of my clients loves how user-friendly Notion is compared to what we currently have. The problem is their current Airtable system was set up around 12 months ago and has many connected processes. They want to avoid the cost of recreating everything from scratch in Notion, but they also don’t want to abandon Airtable entirely.

I need to find a synchronization tool that can:

  • Maintain real-time sync in both directions
  • Process updates quickly (under 60 seconds would be great)
  • Work consistently without breaking
  • Stay within a reasonable budget long-term

I’ve done tons of research online but I really want to hear from people who actually use these tools daily. What sync solutions have you tested? Any issues or limitations I should know about? How’s the pricing working out for you? Any advice would be really helpful!

I’ve been syncing Notion and Airtable bidirectionally for 8 months using n8n. The biggest pain point? Relationship fields and formula columns don’t play nice between platforms and can create sync loops if you mess up the config. I ditched real-time sync after it caused data conflicts when people edited the same record on both sides at once. Now I run syncs every 5 minutes - way more stable. For your client, I’d go with a master-slave setup where one platform owns writes for specific record types. n8n’s pricing beats premium Zapier plans, especially self-hosted. Just know you’ll spend serious time on setup and testing.

Been down this exact road with three different clients over the past couple years. Here’s what I learned the hard way.

Skip bidirectional sync entirely. Seriously. I spent weeks trying to make it work perfectly and it always breaks eventually. Someone edits both sides simultaneously and you get conflicts or duplicate records.

What actually works? Pick Notion as your main interface since your client loves it. Then use Latenode or Make to push specific data to Airtable only when needed. Keep Airtable as your automation engine running in the background.

I had one client who insisted on true bidirectional sync using Integromat. Worked great for two months then started creating phantom records. We rolled back to one-way push and never had issues again.

For your 60 second requirement, webhook triggers work better than polling. Set up Notion to ping your automation platform immediately when records change.

Budget wise, you’re looking at around $50-100 monthly for decent volume if you go with Make or similar platforms. Way cheaper than rebuilding everything.

yea, totally feel ya on that! i’ve used zapier too, mostly works but those complex fields can trip you up. and for sure, costs add up if you’re syncing a lot. make.com is worth a look, might save some bucks!

I’ve set up sync for several clients and Unito’s the most reliable option I’ve found for Notion-Airtable bidirectional sync. Their conflict resolution actually works - when people edit the same record simultaneously, it handles it smoothly instead of creating duplicates or breaking everything. Tested it for four months with a client who had similar needs. Updates sync in 30-45 seconds, which worked for their timeline. Costs around $80/month for the tier that handles most business volumes. Two gotchas though - Airtable’s lookup and rollup fields won’t sync to Notion’s database properties. Had to restructure some data relationships to work around this. Also, initial setup takes longer than other platforms since you need to map fields carefully, but once it’s running it’s solid without the constant maintenance other solutions need.
