The short version

  • Each has a real cost: 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.; NATS core NATS has no persistence at all, so messages are lost if no subscriber is listening
  • They diverge on capability: Mathesar covers Direct PostgreSQL editing, NATS covers Very low latency.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Mathesar

  • A nonprofit or research group whose data is already in PostgreSQL and whose staff cannot write SQLnot NATS
  • Giving analysts a safe editing interface governed by database roles that already existnot NATS
  • Replacing a hand built Django or Rails admin screen that nobody wants to maintainnot NATS
  • Editing production reference data where an export, edit and reimport cycle would risk losing concurrent changesnot NATS

NATS

  • Service-to-service messaging where latency is the binding constraintnot Mathesar
  • Edge and IoT messaging where a lightweight broker mattersnot Mathesar
  • Replacing a heavier broker when the workload does not need its guaranteesnot Mathesar

Where each one falls short

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

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.

NATS

  • Core NATS has no persistence at all, so messages are lost if no subscriber is listening
  • JetStream adds the durability but also the operational complexity NATS is chosen to avoid
  • A much smaller ecosystem than Kafka or RabbitMQ, with fewer connectors and integrations
  • Fewer people know it, so hiring and existing organisational knowledge favour the alternatives

Answered from the vendors’ own pages

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.

NATS: Is NATS free?

Yes, open source and CNCF-graduated. Synadia sells a managed service.

Mathesar: How does it handle permissions?

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

NATS: Does NATS persist messages?

Core NATS does not — it is fire-and-forget. JetStream adds persistence, streaming and replay when you need them.

Mathesar: What is the row limit?

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

NATS: NATS or Kafka?

NATS is far lighter and lower latency, and much simpler to run. Kafka is the answer when you need a durable replayable log and a large connector ecosystem.

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.
