No it's a full story, more akin to zero (at the highest level that is, many many differences and trade-offs).

Unfortunately I'm not qualified to answer that last question... I'm on the PowerSync team. What I can say is that we get a lot of praise from users (the ones that survive onboarding that is, lots of DX improvements we still need to make)

Wonder why PowerSync isn't on the radar for a post like this, not evaluated or didn't make the cut for worth mentioning?

Appreciate the noise filter.

Who would've guessed - a dip in price means more sellers than buyers :mindblown:

New comment by kobieps in "Ask HN: Which is the best sync engine?"

kobieps — Tue, 06 Jan 2026 20:45:38 +0000

I suppose the only part the OP would need to look at is "Being able to form and execute queries in my backend" for the read path, since Sync Rules / Sync Streams need to define those queries. For the write path, you should be able to re-use the existing APIs / permission middleware for the most part.

Then: "Further, I wonder how such a system would work with connection pooling, sharding, replication etc."

These are all topics on their own, but briefly: - Connection Pooling: Not supported in PowerSync Cloud atm, but supported in theory when self-hosting since pgbouncer 1.23 added WAL support. Having said that, clients connect to the PowerSync Service for sync operations, so you only need a single direct connection between the service and your postgres. - Sharding: PowerSync can be used in a sharded setup [1], with better support planned - Replication: PowerSync uses the Postgres WAL for replication [2]

PowerSync | Senior Backend Engineer and Database Expert | Full-time | Remote (opt-in regional offices)

PowerSync is a sync engine that keeps your backend database in sync with on-device SQLite. We support Postgres, MySQL, MongoDB and SQL Server as source databases and have a plethora of client SDKS, many of which are integrated with popular libraries and frameworks on the client-side like TanStack DB, Drizzle, GRDB, Room, etc

If you're a database enthusiast and have a solid track record of building, deploying and maintaining backend systems on modern cloud stacks at scale, please check us out.

Detail: https://www.powersync.com/careers/senior-backend-engineer-an...

Our team is small and polyglot, but experience with TypeScript is a must.

Experience with OSS projects is also a must - either you've made significant contributions to popular devtool projects or, better yet, you have your own.

Culture: We're agile and devops purists (before those terms got coopted)

Haha fair, but in this case it was "loses the time if the power supply is interrupted"

kobieps — Wed, 24 Dec 2025 20:55:23 +0000

Cool, makes sense. We still want to write a blog post about how we built powersync that will go into more detail on the points you raised.

The one thing I'll add is we found "keeping UI responsive while syncing in the background" is highly platform dependent since all platforms have their quirks, but for React Native we have a detailed blog post and code (admittedly tightly coupled to powersync, but should provide a starting point) https://www.powersync.com/blog/keep-background-apps-fresh-wi...

kobieps — Tue, 23 Dec 2025 12:32:54 +0000

Not sure if you're open to using tools for this, but PowerSync solves those tricky things you listed (and many more you didn't list (disclaimer I'm on the team))

We also have docs for common offline-first use cases. For temporary client IDs, see https://docs.powersync.com/usage/sync-rules/client-id#postgr...

Those strategies are broadly applicable no matter the stack, PowerSync just takes care of some of the details.
