aiven.io/pricing/postgresql · managed Postgres and friends with a free plan that powers off on inactivity · databases-kv/aiven-free · JSON · compare

Free tier	Free plan with 1 GB RAM and 1 GB total storage per service, on Postgres, MySQL, Valkey, Kafka and OpenSearch; free indefinitely with no time limit, but the service powers off after a period of inactivity unit GB; metered on stored-bytes
Price	none stated
Per-object cap	1 GB total storage per service
Retention	the service powers off after a period of inactivity, on three triggers: no initial usage in the first few hours, or no continuative activity later; a powered-off service is deleted after 180 days. The Free plan is the exception to 'data retention is only limited by storage' (180 days)
Egress	no egress allowance, quota or per-GB rate is published on the free-plan pages or the PostgreSQL pricing table; recorded as a gap after checking both
Identity	email email signup; no card on the Free plan
Limits	per-object-cap 1 GB total storage per service; 1 GB RAM source retention-clamped the free service powers off after a period of inactivity; a service powered off for more than 180 days is automatically deleted source request-rate max_connections is set to 20 on a free PostgreSQL service, and there is no connection pooling source
Binding	retention-clamped 1 GB of storage is small, but the inactivity power-off is what defeats the use a reader would pick this for: an unattended job that runs less often than the inactivity window. The 180-day deletion sets the outer limit.
Interface	rest, cli the Postgres wire protocol; an API and the avn CLI
Tooling	psql and any Postgres client; the avn CLI
Composes with	no longer a candidate for a weekly or monthly job: the free service powers off on inactivity and is deleted 180 days after it powers off, so a keep-alive is required and the paid Developer tier is what removes the clock
Reliability	free services power off on inactivity and a service powered off for more than 180 days is automatically deleted; a powered-off service for a version past end of life is deleted within 7 days
Notes	1 GB is the smallest free Postgres storage in this class, and the free plan powers off on inactivity, so it does not answer the question the class was formed to ask. 5 GB is what the plan used to give and several comparison pages still print it. The paid Developer tier at USD 5 a month is the version of this that stays up: 'Developer tier services are not automatically powered off when inactive'.
Evidence rung	documented three first-party Aiven pages were read today: the pricing page for 1 GB RAM and 1 GB storage, the free-PostgreSQL page for the inactivity power-off, and the service power-cycle page for the 180-day deletion.

2026-10-22 Aiven's free plan was recorded as the one that never pauses, and it powers off on inactivity

Free tier	New accounts include $300 in free credits and no payment details are required to sign up. The documentation states 'Aiven offers a free trial for 30 days with credits you can use to explore the Aiven Platform. You don't need a credit card to sign up.' The amount and the duration are on two different pages. unit mixed; metered on wall-clock
Price	none stated
Per-object cap	not applicable: the offer is a spending balance, not a stored object
Retention	the trial runs 30 days; the free service tier is separate and unlimited (30 days)
Egress	not stated on the pages read
Identity	email no payment details are required to sign up; Google, Microsoft, GitHub or email; the console is JavaScript-only so the form fields were not observed live
Limits	volume-quota USD 300 of credit over a 30-day trial source the amount is published on the developer-tier page and the 30 days on the service-pricing documentation; the /free-trial/ path returns 404
Binding	volume-quota USD 300 over 30 days is 41.7 cents an hour, and the balance is the only thing that ends the trial
Interface	rest, cli the Aiven console, the Aiven CLI and per-service connection URIs; no general-purpose VM
Tooling	the Aiven CLI, the Terraform provider, and each service's native client
Composes with	the credit pays for managed PostgreSQL, Kafka, Valkey and the rest at list price; it does not buy a machine that runs arbitrary software
Reliability	the free service tier continues indefinitely and is separate from the trial credit, so a service can outlive the balance on the Free plan
Notes	The credit buys managed services only. The smallest paid plans are Developer at $5 a month (1 CPU, 1 GiB, 8 GB) and Hobbyist at $12 a month or $0.02 an hour (1 CPU, 1 GiB, 8 GB). A general-purpose process cannot be hosted here.
Evidence rung	documented two first-party Aiven pages were read on 2026-10-23; the trial URL carried by the search index is dead, so the amount and the duration are each sourced from the page that still carries them

Free tier	1 GB disk each for PostgreSQL, MySQL and Valkey (Valkey maxmemory = 50% of 1 GB RAM = 512 MB usable); 20 GB storage for OpenSearch; Kafka free tier is throughput-capped at 250 KiB/s. 'Only one service of each service type in your organization.' No time limit, no credit card. unit GB; metered on stored-bytes
Price	none stated
Per-object cap	not stated
Retention	not stated
Egress	Free — 'Network traffic is not charged separately' (Aiven service pricing doc). This is the best egress term of any structured store here, which makes the tiny byte quotas the only blocker.
Identity	card derived from the record's prose, not from an identity field, and no signup was executed: each service type in your organization.' No time limit, no credit card. Aiven 'reserves the right to power off free services with no initial usage in the first few hours' and to power off
Binding	none no constraint of a named kind was recorded; the verdict rests on the quota sentence rather than on a named limit
Interface	rest, cli rest
Tooling	psql / mysql / redis-cli / OpenSearch REST API / any Kafka client; Aiven Terraform provider and `avn` CLI for provisioning; PG-wire and RESP protocols unchanged
Composes with	One service of each type per ORG (verified in the Valkey free-tier doc: 'Only one service of each service type in your organization'). So one org yields ~1 + 1 + 0.5 + 20 GB = ~22.5 GB across four services, plus Kafka. 23 orgs would reach 500 GB — the best per-org yield of any structured store found, and the only one where egress is genuinely free.
Reliability	Aiven 'reserves the right to power off free services with no initial usage in the first few hours' and to power off services with no continuing activity. For a cold archive that means keep-alive traffic is mandatory or the service sleeps. No data loss reported, just power-off.
Notes	1 GB disk each for PostgreSQL, MySQL and Valkey (Valkey maxmemory = 50% of 1 GB RAM = 512 MB usable); 20 GB storage for OpenSearch; Kafka free tier is throughput-capped at 250 KiB/s. 'Only one service of each service type in your organization.' No time limit, no credit card.
