We would love to hear from you and your colleagues, shares are welcome 📣
Help shape the future of @couchdb.bsky.social! 📣
It’s time for the 2025 - 2026 Annual Apache CouchDB User Survey, where we learn what to build, write about and enhance.
Boosts and shares appreciated — let’s reach as many users as we can! 🌐
There’s more than one way to automate #OfflineFirst database conflicts
@couchdb.bsky.social makes it easy and notoriously reliable by choosing a deterministic winner and storing conflicts
The best part?
🖼️ You can manage conflicts in CouchDB’s built-in UI!

The Annual Apache @couchdb.bsky.social User Survey 2025 is here! We want to hear from you 📣
Using ✨ 3.5.1 ✨ yet? Prefer another version? Want more of something? Wouldn’t miss it if something went away?
Let us know until late Feb 2026! 🔽

I’m looking forward to playing with this. I love working in CouchDB.
- native support for UUIDv7
- substantial speedups for bulk operations, purge operations and any btree operations by introducing a cache
- support for Debian Trixie
- Erlang 26 as minimum version
- Allow safe downgrading of CouchDB versions
Which makes it a pretty cool release :)
AMA.
Most surprising though is that the scanner found more differences in SpiderMonkey versions (1.8.5, 76, 81, 115, 128) than SpiderMonkey vs QuickJS. We’ve copiously documented the differences: docs.couchdb.org/en/stable/be...
That said, the 3.5.1 highlights aside from bugfixes are:
…
Since version 3.4 which introduced QuickJS, CouchDB ships with a background scanner module that will urn your SpiderMonkey JS in QuickJS and reports any incompatibilities. That you you can know ahead of time if it is safe to migrate:
neighbourhood.ie/blog/2024/09...
- we even had to ship 3.5.1 with just QuickJS because RHEL/Alma 10 doesn’t do SM anymore at all.
QuickJS is smaller, faster, lower memory footprint and we made it safe to migrate.
We’ve lost a lot of developer hours to the fact that SpiderMonkey is fundamentally a JS engine for Firefox and not really set up to be a library.
- we had to keep up with minute API changes across major versions
- we have to support a wide range of versions due to spotty OS package support
Heads up for the next feature release 3.6.0: QuickJS will take over from SpiderMonkey as the default JavaScript engine.
New version! CouchDB 3.5.1 is now available. It is a maintenance release with a lot of bug fixes, but it also includes a number of substantial performance improvements: blog.couchdb.org/2025/11/11/3...
What if your database just… worked? 🤔
User data isn’t lost…
It works on the web…
It has built-in sync, for #offline and #local apps from day 1…
And it’s got a proven track-record…
Some of you know it already exists — it’s @couchdb.bsky.social ! ✨
Take a look: neighbourhood.ie/blog/2025/08...
Congratulations @couchdb.bsky.social 🥳 🎉
Apache CouchDB ’s application to @sovereign.tech’s Tech Resilience program was successful!
We’ll share details of CouchDB’s enhanced durability once improvements are shipped.
You can do the same for your #FOSS project: www.sovereign.tech/programs/bug...
A graph that maps number of requests against time in seconds shows a staggering climb that peaks at 63.21K requests per second, before winding back down to a low baseline.

This year we got to help a customer make huge gains 📈

In this diagram of a database sharded using consistent hashing, the database is represented by a large rectangle. It contains small squares representing individual documents from A to G with an ellipses indicating continuation. Below this are 4 smaller rectangles, representing a q value of 4. Each smaller rectangle contains two documents, and the row is not alphabetical.
#Sharding is (another) thing that makes @couchdb.bsky.social such a scalable distributed database 📐
Few DBs make it automatic & transparent as CouchDB.
We cover:
- what shards are
- how #CouchDB uses them
- performance gains and trade-offs

Recap time!
Last week we attended @localfirstconf.com, hosted a packed workshop (thanks to all who joined!) and shared @couchdb.bsky.social stories on stage.

Can’t wait for next year! ✨
Fresh CouchDB, get your fresh CouchDB! Truly parallel shard reads/writes (+40% throughput), a conflict finder, faster integrity checking and more secure password hashing on by default, more built-in reducers, lots more.
The detailed change log is quite the fun read: docs.couchdb.org/en/stable/wh...
Want to try CouchDB’s 🆕 Minihosting + see the state of Offline-First in 2025 at the same time?
We’ve put together a demo app tutorial to do just that! See how @svelte.dev 5, @vite.dev , Pico.css, @couchdb.bsky.social and PouchDB come together to make Pouchnotes: neighbourhood.ie/blog/2025/03...
“What even is CouchDB?”
😌 It’s the database that *expects* things to fail — and keeps working anyway.
Take a look to discover why @couchdb.bsky.social’s offline-first design, seamless sync and JSON/HTTP API help ensure it never panics: dev.to/neighbourhoo...
💬 What’s your favourite feature?
CouchDB 3.5.0 is now available for download. It includes a number of impressive performance improvements, chief among them: truly parallel read and write access to database shards leading to up to 40% more throughput on high-volume request loads.

Using @couchdb.bsky.social for science!
Archeology gets a lot more collaborative when using offline-first laptop software for data sharing while the dig is happening, not months later.
Don’t take my word for it, Dr. Lisa Steinmann from the German Archeological Institute shares her insights:
Archaeologists! Field researchers! 📣
How do you handle data collection when working remotely with no internet?
The @dai-weltweit.bsky.social’s iDAI.field app is #Offline-First and ensures zero data loss + seamless sync: neighbourhood.ie/blog/2025/03...
Need a similar solution? We’d love to help!
Want to boost @couchdb.bsky.social query performance? Cut out inefficiencies with partitions 🔪
Instead of querying them all, partition your data so you just need to query *one* shard.
