The short version

  • Only Mathesar has a free tier, so it costs nothing to try first.
  • Each has a real cost: Instaclustr pricing is only obtainable through a configurator or sales conversation, so comparing against AWS MSK or Confluent list prices requires several rounds of quotes rather than a spreadsheet.; Mathesar there is no hosted offering of any kind, so a team without someone who can run and secure a server cannot use it at all.
  • They diverge on capability: Instaclustr covers Unmodified open source, Mathesar covers Direct PostgreSQL editing.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Instaclustr

  • Pricing is only obtainable through a configurator or sales conversation, so comparing against AWS MSK or Confluent list prices requires several rounds of quotes rather than a spreadsheet.
  • It manages infrastructure, not data modelling, so a poor Cassandra partition key or a mis-sized Kafka topic still causes outages that the managed service will not prevent.
  • NetApp ownership since 2022 has put the roadmap inside a large storage vendor, and the product is now one line in a portfolio rather than the whole company.
  • The catalogue is broad but each technology is served at a general level, so teams needing deep, vendor-specific tuning often find a specialist provider goes further on their one technology.
  • Bring your own cloud reduces lock-in but shifts networking, IAM and VPC peering complexity onto the customer, which needs cloud engineering capacity the managed service was meant to save.

Mathesar

  • There is no hosted offering of any kind, so a team without someone who can run and secure a server cannot use it at all.
  • It works only with PostgreSQL, so a MySQL, SQL Server or SQLite estate is excluded outright.
  • There are no automations, no webhooks and effectively no integration catalogue, so it edits data and does nothing else.
  • Because it writes to the live database, a careless bulk edit or column type change is a production change with no staging step and no undo.
  • Development is grant and community funded rather than commercially funded, so roadmap pace and long term continuity carry a different risk profile from a venture backed vendor.

Answered from the vendors’ own pages

Instaclustr: Does Instaclustr modify the open source software?

No. Its stated commitment is one hundred per cent open source with no proprietary extensions, which is the main reason licence-averse buyers choose it.

Mathesar: Is there a cloud version?

No. Self hosting is the only option, and that is a deliberate project decision rather than a gap waiting to be filled.

Instaclustr: Who owns Instaclustr?

NetApp, which acquired the company in 2022. It is now branded NetApp Instaclustr.

Mathesar: How does it handle permissions?

Through PostgreSQL roles and privileges directly, so there is no second permission model to keep in step.

Instaclustr: Is pricing published?

No. There is an interactive calculator, but figures depend on technology, node size, cloud and region, and commitments are negotiated.

Mathesar: What is the row limit?

Whatever PostgreSQL can handle. Mathesar adds no storage layer of its own.

Instaclustr: Can clusters run in my own cloud account?

Yes, through the bring-your-own-cloud model, so the infrastructure spend also counts toward your cloud commitment.

Mathesar: Does it support databases other than PostgreSQL?

No.

Mathesar: Can it replace Airtable?

Only for editing and exploring data. There are no automations, apps or integrations.
