Is HAProxy or Readyset better?

Neither clearly leads. HAProxy starts at Free and Readyset at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, HAProxy or Readyset?

HAProxy starts at Free and Readyset at Free.

Does HAProxy or Readyset run on more platforms?

HAProxy runs on Linux, Docker, Kubernetes, Self-hosted. Readyset runs on Cloud, Self-Hosted.

Can I use HAProxy for free?

Both have a free tier, so you can try either at no cost before committing.

What is HAProxy best used for?

HAProxy is most often used for load balancing at traffic levels where proxy efficiency shows up in the hardware bill, precise traffic control — rate limits, sticky sessions, complex routing rules, tcp load balancing for databases and non-http services. Of those, load balancing at traffic levels where proxy efficiency shows up in the hardware bill and precise traffic control — rate limits, sticky sessions, complex routing rules are not what Readyset is typically brought in for.

What can HAProxy do that Readyset cannot?

HAProxy covers High throughput, Layer 4 and 7, Health checking, Rate limiting and ACLs. Readyset covers Automatic Query Optimization, SQL-Level Caching, Live Incremental Updates, Zero-Touch Integration.

Where each one falls short

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

HAProxy

Configuration syntax is dense and unforgiving, with a steep initial learning curve
No automatic certificate management, unlike newer servers that treat it as default behaviour
The built-in stats page is basic, so real observability needs exporters and dashboards
A dedicated load balancer is more machinery than small deployments need

Readyset

Pricing requires contacting sales team, making cost planning difficult
Specific pricing tiers not disclosed publicly
Requires cache size estimation for cost calculation
Limited to read query caching, does not address write performance

HAProxy: HAProxy or Nginx?

HAProxy is a specialist load balancer with deeper balancing and health-check features. Nginx also serves static content and is more approachable, which is why it is more common as a general web server.

Readyset: Is there a free trial?

Yes, Readyset offers a free 7-day trial that lets you test different cache sizes before committing to a paid plan.

HAProxy: Does HAProxy handle TLS certificates automatically?

No. Certificate issuance and renewal are external, unlike Caddy where it is automatic.

Readyset: How does Readyset pricing work?

Readyset is available as a monthly or annual subscription charged based on the size of cache you need. Contact [email protected] for specific pricing.
