The short version
- Each has a real cost: Aiven the free plan gives 1 VM with 1 CPU, 1 GB RAM and 1 GB storage, and cannot pick a specific cloud or region; Timeplus proton, the free version, is single-node by design, so any requirement for high availability or horizontal scale forces the commercial licence; the open source edition is a trial in practical terms.
- They diverge on capability: Aiven covers Multi-cloud Support, Timeplus covers Streaming SQL.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Aiven
- The free plan gives 1 VM with 1 CPU, 1 GB RAM and 1 GB storage, and cannot pick a specific cloud or region
- Free and Developer tiers have no integrations and no connection pooling
- Connection pooling, database forks and dynamic disk sizing need the Business or Premium plan
- A 99.99 percent uptime SLA starts at the Startup plan from $75 a month
- High availability with automatic failover starts at Business from $180 a month
Timeplus
- Proton, the free version, is single-node by design, so any requirement for high availability or horizontal scale forces the commercial licence; the open source edition is a trial in practical terms.
- It is a young project against Apache Flink’s decade of production history, so the hiring pool, the connector library and the body of known failure modes are all much smaller.
- Inheriting ClickHouse internals also inherits ClickHouse constraints: memory-hungry queries, awkward updates and a SQL dialect that is not portable to other engines.
- Exactly-once semantics and state recovery guarantees are less battle-tested than Flink checkpointing, which matters if the pipeline moves money.
- Cloud pricing is by provisioned instance size rather than usage, so a bursty workload pays for peak capacity around the clock or has to be resized by hand.

Answered from the vendors’ own pages
Aiven: What does Aiven's free tier include and does it have any time limit?
The free tier includes PostgreSQL with 1 VM, 1 CPU, 1 GB RAM, and 1 GB storage with access to limited cloud and region selections. There are no time limitations on the free tier, though Aiven reserves the right to shut down accounts that violate policies or remain unused for extended periods.
SourceTimeplus: Is Timeplus open source?
The core engine, Timeplus Proton, is Apache 2.0. Timeplus Enterprise and Cloud are commercial.
Aiven: How is Aiven billed and what are the monthly costs for each tier?
Aiven bills services by the hour and invoices monthly, charging only for what you actually run. PostgreSQL pricing starts at 5 dollars per month for Developer, 12 dollars per month for Hobbyist, 75 dollars per month for Startup, 180 dollars per month for Business, and 270 dollars per month for Premium. All paid tiers offer hourly billing options as well.
SourceTimeplus: What is the difference from Flink?
Timeplus is one binary with SQL as the only interface; Flink is a JVM cluster with a Java and SQL API and far more operational surface.
Aiven: What backup retention periods are included at different Aiven tiers?
Backup retention increases with tier level: Startup tier provides 2 days of backup retention, Business tier offers 14 days, and Premium tier includes 30 days. Point-in-time restore is available on all paid tiers.
SourceTimeplus: Can Proton run in production?
It can, but it is single-node only, so there is no high availability without the commercial edition.
Aiven: Is high availability included in Aiven pricing or charged separately?
High availability, backups, and routine maintenance are all included in the tier costs with no separate charges. The Business tier includes 2 VMs with automatic failover, and Premium includes 3 VMs with a second standby node.
SourceTimeplus: How much is the cloud?
From 199 US dollars a month, sized by CPU and memory, with a fourteen day trial.
Aiven: Does Aiven offer a trial period to test premium features?
Aiven offers a 30-day free trial to access premium features beyond what the free plan provides.
