Aiven alternatives: one plan instead of one bill per service

Short version: Aiven is a good platform with a pricing model that punishes stacks made of more than one thing. Every service carries its own plan and its own hourly meter, so a Postgres, a MySQL, and a Valkey are three separate decisions and three separate charges. Layerbase Cloud sells one plan that covers up to 10 databases across 18 engines. If your whole world is one Postgres, the gap is small. If it is four services, the gap is the entire bill.

What Aiven actually is

Aiven is an open source data platform, and the databases are not the headline. Kafka is. Then Flink, OpenSearch, and Grafana, with PostgreSQL, MySQL, Valkey, and ClickHouse sold alongside them as managed services on the same control plane. If you are running a streaming pipeline and you want the broker, the stream processor, the search index, and the dashboards from one vendor in one cloud region, that is a coherent product and there is not much like it.

We do not compete with that half at all. We host databases. If Kafka is why you are on Aiven, close this tab.

The part worth comparing is the other half: the ordinary application databases you keep next to your app. That is where the pricing model gets expensive, and it gets expensive in a way that has nothing to do with how much you use.

The meter is per service

Aiven bills hourly, per service, and each service is priced independently. Their own pricing page tells you to price each service on its own and add the results together. That is honest, and it is also the whole problem: adding is exactly what your invoice does every time your stack grows a component.

Here is the PostgreSQL ladder, verified 2026-08-26 from aiven.io/pricing.

Two things to read off that table. High availability starts at Business, so every plan under $180 a month is one node. And each rung is per service: the MySQL ladder and the Valkey ladder are their own ladders, charged their own way.

Now the arithmetic. Say your app needs a Postgres, a MySQL you inherited, and a Valkey for sessions and queues. On Aiven that is three Developer services at $5 each, which is $15 a month, split across three plans you chose separately, each single node, each capped around 8 GB of storage.

Fifteen dollars a month for three databases is not outrageous. That is the point I want to be fair about. What matters is what happens next, because on Aiven the fourth service is another decision and another line, and the fifth is another one after that.

On Layerbase, $15 a month is Pro: up to 10 databases, 25 GB of storage across them, every one of the 18 Cloud engines available, one bill. Adding the vector store next quarter is a create button, not a purchasing decision. The number stops moving.

Smaller than that, the shape is the same. Two databases on Aiven Developer is $10 a month in two plans. Two databases on Layerbase is Solo at $5 a month with 10 GB, and Solo comes with a 768 MB always-on pool: pin the database that has to stay awake and it never sleeps, while the second one hibernates when idle and wakes on connect.

One honest asterisk on the comparison. Aiven's Developer tier gives each service its own dedicated plan resources. Our shared plans run your databases out of a pool, and the pool is what bounds them. If you need a guaranteed box per database, that is our dedicated tier, not Solo, and the pricing page has those numbers.

Both free tiers, described accurately

Aiven's free tier is a real free tier and it deserves credit for that. Verified 2026-08-26 from aiven.io/free-tier and the free plan documentation: always free rather than a trial, no expiry, no credit card, backups included.

The constraints are where the two differ. Aiven gives you one free service per service type: one PostgreSQL, one MySQL, one Valkey, and that is the ceiling. Each free service is a single node with 1 GB of RAM and 1 GB of storage. VPCs, static IPs, forking, and choosing your cloud and region are all excluded. Free services that sit idle get powered off, and Aiven notifies you first and lets you power the service back on yourself.

Layerbase Free is $0 with no card, 2 databases with 5 GB of storage between them, drawn from 8 Standard engines: PostgreSQL, MariaDB, SQLite, DuckDB, libSQL, Redis, Valkey, and TypeDB. Each free database gets one instant branch. Idle databases sleep after 15 minutes and wake when you connect, which is the difference I would weigh most: nobody has to go press a button, because reconnecting is the button.

The trade is real in both directions. Two databases on Layerbase Free can both be Postgres if that is what you need, which Aiven's one-per-type rule does not allow. Aiven Free will hand you a Postgres and a Valkey and a MySQL simultaneously, which is three engines to our two databases. And MySQL is not on our free tier at all: it starts on Solo, and ClickHouse starts on Pro. Aiven's ClickHouse has no free plan either, so on that one we are even.

The Redis story, told with dates

If you are searching for "Aiven Redis" and finding nothing, here is why, straight through, verified 2026-08-26.

Aiven for Redis was renamed Aiven for Caching when Redis changed its license, pinned at Redis 7.2.4, which was the last version under the old terms. Services were then auto-upgraded to Aiven for Valkey after 2025-03-31. Aiven for Caching was decommissioned starting 2025-10-15. There is no Aiven Redis product now.

I am not going to spin that as a betrayal, because it was the reasonable response to a license change Aiven did not make, and Valkey is the Linux Foundation fork the rest of the ecosystem landed on too. Aiven was an early and loud backer of Valkey and it went the way they said it would.

The reason it appears in a post about alternatives is narrower: if you moved because of that migration, and you are re-evaluating anyway, we host Valkey. It is on our free tier. So is Redis, for the versions we can still ship, so a redis:// connection string does not have to become a project.

What Layerbase does not have

Four gaps, plainly, before the migration section talks you into anything.

Kafka, Flink, OpenSearch, and Grafana. We host none of them and there is no plan on a whiteboard for them. If your Aiven account has a Kafka cluster in it, you are keeping the Aiven account no matter what the database half of the bill looks like.

A guided path for every engine. The Aiven migration wizard covers PostgreSQL and Valkey today: paste the Service URI and the copy runs. MySQL is not in the wizard yet, because an Aiven dump needs mysqldump --set-gtid-purged=OFF and our remote dump does not pass that flag yet. It is coming, and until it lands the manual mysqldump --single-transaction --set-gtid-purged=OFF route works today and is the one documented below. ClickHouse is not covered either, so moving an Aiven ClickHouse service is a dump and load you do yourself.

Bring your own cloud and VPC peering. Aiven will run services inside your own cloud account and peer into your VPC. We run our own fleet, and databases reach the public internet over TLS. For a team with a network security posture written down and audited, that is a hard requirement and we do not meet it.

Their compliance surface. Aiven is a large vendor selling to enterprises with the attestations and the procurement paperwork to match. We are a small company. If your buyer needs a specific certification on file before signing, ask us before you plan a migration rather than after.

There is a fifth I will fold in here rather than pretend away: Aiven Business adds a standby node. We do not offer a replica at any plan. Every Layerbase database is a single node with backups. If losing the primary means losing minutes rather than seconds, that is a real architectural difference, and $180 a month is what it costs there.

Moving a database across

The Aiven side of this is genuinely easy, which is worth saying about a competitor. Every service puts a full Service URI on its Overview tab. Copy it and you have everything: host, the random high port Aiven assigns, the avnadmin user, the defaultdb database, and the password. TLS is always on, and sslmode=require works without downloading the project CA. You only need the CA for verify-ca or verify-full, which use Aiven's per-project private certificate authority. Valkey services hand you the same thing under a valkeys:// scheme. The IP filter on a new service defaults to 0.0.0.0/0, so in most accounts there is no firewall change to make first.

Paste that URI on the Aiven migration page. We connect once, copy the schema and the data, and disconnect. Your Aiven service is read and never written to, and it keeps serving traffic the whole time. It is a one-shot copy rather than live replication, so pick a cutover window. PostgreSQL and Valkey go through that wizard; MySQL is the manual route below until the flag work lands.

If you would rather dump it yourself, know the one constraint that shapes every Aiven export: avnadmin is not a superuser. Aiven says so directly, which is why their own recommended pg_dump recipe passes --no-owner --no-comments. Ownership and comments on objects you do not own are exactly what a non-superuser dump cannot reproduce. On the MySQL side their docs require mysqldump --set-gtid-purged=OFF, for the same class of reason, and --single-transaction is what keeps the dump consistent while the service stays up:

mysqldump --single-transaction --set-gtid-purged=OFF \
  --routines --triggers \
  -h mysql-yourproject.a.aivencloud.com -P 12345 -u avnadmin -p defaultdb \
  | mysql -h <host>.cloud.layerbase.dev -P 3306 -u layerbase -p appdb

Both flags are about the source, not the destination, so they apply wherever you are moving to.

Once the data is across, the workflow changes in one way that is worth the move on its own. Branch it. 16 of our Cloud engines branch, copy-on-write, in seconds, so a preview deployment or a CI run or an agent gets an isolated copy of real data instead of a seed script. It comes out of your plan's branch allowance rather than being a second thing you buy.

When to stay on Aiven

Not a formality. Four cases where staying is correct:

• Kafka, Flink, or OpenSearch is in the account. The databases are the small half of your bill and consolidating them elsewhere splits your platform for no gain.
• You need a standby node. Aiven Business has one and we do not. This is the clearest reason on the list.
• You need BYOC, VPC peering, or a specific region. We run our fleet; you cannot run ours inside your cloud account.
• You are on one Aiven service and the bill has never surprised you. One Developer Postgres at $5 a month is a fine deal. Flat pricing solves a problem you do not have yet.

The case for moving is strongest when your Aiven console has three or four small services in it, none of them large, all of them billed separately, and the total went up every time your app grew a feature.

FAQ

What is the best Aiven alternative?

It depends which Aiven you mean. For the streaming platform, nothing here replaces it. For the ordinary application databases sitting next to it, a flat plan that covers all of them costs less and stops moving as you add services. Layerbase Cloud hosts 18 engines on one account, with up to 10 databases on the $15/mo Pro plan.

How does Aiven's pricing actually work?

Hourly, per service, with each service priced on its own plan ladder. Aiven's pricing page instructs you to price each service independently and add them together. Verified 2026-08-26: PostgreSQL runs Free, Developer $5/mo, Hobbyist from $12/mo, Startup from $75/mo, Business from $180/mo, Premium from $270/mo, and high availability starts at Business.

Is the Aiven free tier really free?

Yes. Verified 2026-08-26: always free with no expiry, no credit card, backups included. The limits are one free service per service type, a single node with 1 GB of RAM and 1 GB of storage, no VPCs, no static IPs, no forking, and no choice of cloud or region. Idle free services get powered off after a notification, and you power them back on.

What happened to Aiven for Redis?

It became Aiven for Caching when Redis changed its license, pinned to Redis 7.2.4. Those services were auto-upgraded to Aiven for Valkey after 2025-03-31, and Aiven for Caching was decommissioned starting 2025-10-15. Aiven no longer sells a Redis product. Layerbase hosts Valkey on the free tier.

Where do I find my Aiven connection string?

On the service's Overview tab, as the Service URI. It carries the host, the assigned high port, the avnadmin user, the defaultdb database, and the password. TLS is always on and sslmode=require works without the project CA; you need the CA only for verify-ca or verify-full. Valkey services use a valkeys:// scheme.

Why does my Aiven pg_dump complain about ownership?

Because avnadmin is not a superuser. Aiven does not allow superuser access, so a dump cannot reproduce ownership and comments for objects it does not own. Their own recipe is pg_dump --no-owner --no-comments, and the MySQL equivalent is mysqldump --set-gtid-purged=OFF.

Can I get an isolated copy of my data for previews?

Yes. A Layerbase branch is copy-on-write, arrives in seconds, and comes out of your plan's branch allowance rather than being a second service you provision and pay for. 16 Cloud engines support it.

Starting

If you have data in Aiven, the shortest path is the Aiven migration page: copy the Service URI off the Overview tab, paste it, and let the copy run while the service keeps serving.

Starting clean is create a PostgreSQL database on the free tier. No card, 2 databases, and the same connection string format your driver already expects.

Aiven priced each service honestly. The bill just adds them up, and most stacks are not one service.
