Selfhost.dev vs
AivenSelfhost.dev and Aiven both run standard managed PostgreSQL, but Aiven makes you pick a tier, and its first production-ready plan jumps to $250/mo with nothing between the $5 developer box and that. Selfhost.dev runs the same 2 CPU / 4 GB / 80 GB box for about $40, pay-as-you-go, with connection pooling, PG version choice, BYOC on your own AWS, and 150+ MCP tools included from the start.

TL;DR
The short
version.
Aiven jumps from a $5 developer box straight to $250/mo for its first production plan (2 CPU / 4 GB / 80 GB, single node). The same box on Selfhost.dev is about $40, roughly 6x less, prepaid and pay-as-you-go.
Selfhost.dev offers BYOC on your own AWS account at a transparent management fee, while Aiven reserves BYOC for enterprise custom pricing.
150+ MCP tools you drive from Claude, Cursor, or VS Code in plain English, editor-side. Aiven has no equivalent.
Pricing comparison
$5 to $250,
nothing in between.
Aiven asks you to pick a service tier first: Free, Developer, then Professional. The two cheap tiers are feature-limited, and the first real production plan is a steep jump.

Deep dive
Where the
differences matter.
Cheap tiers are toys, production is a jump
Aiven's Free tier is a 1 GB box that powers off when idle, with no backups or pooling. Developer at $5 is always-on but still has no connection pooling, no PostgreSQL version choice, and only continent-level region control. The first plan that is genuinely production-ready is Professional at $250/mo for a single-node 2 CPU / 4 GB / 80 GB instance. Selfhost.dev runs that same box for about $40, pay-as-you-go, with pooling, version choice, config tuning, and 150+ MCP tools included from the start. Pooling, automated backups, PITR, and Multi-AZ are handled for you: production Postgres without a DBA hire or the 3am firefighting.
BYOC without enterprise pricing
Aiven restricts BYOC to enterprise contracts with custom pricing. Selfhost.dev offers BYOC on your own AWS account at a transparent management fee, accessible to startups and small teams, not just enterprise.
Multi-cloud breadth, if you need it
Aiven is a genuine multi-cloud platform: AWS, GCP, Azure and more, plus a wide catalog of services (Kafka, Valkey, ClickHouse, OpenSearch) beyond Postgres. If you need that spread on one vendor, Aiven is purpose-built for it. Selfhost.dev runs managed PostgreSQL on AWS with Graviton price/performance and stays focused on Postgres, so if Postgres is your stack you get deeper features, AI/MCP control, and BYOC for a fraction of the cost.

Migration
Switching from Aiven?
We migrate you, free.
There is no migration tool to fight with, because you get people instead. A Selfhost.dev engineer plans and runs the move with you, end to end, at no extra cost.
Your Aiven plan, data size, and Postgres version: the free cost audit form is enough. You get the exact monthly number and a migration plan before anything moves.
Aiven runs standard PostgreSQL, so your data moves with standard tooling: logical replication for a near-zero-downtime cutover, or pg_dump and restore for smaller databases. Nothing proprietary in, nothing proprietary out.
We verify a restore on the new instance first, and you flip the connection string only when you are satisfied. Your version and extensions come with you.
Free on every plan size. If the numbers do not work for you, you keep the breakdown.
