Load Balancing Software Resources

Hi G2, I'm trying to work out which load balancing platforms practitioners at enterprise SaaS companies actually trust, using G2 ratings and review themes. From the load balancing category, with ratings:

• HAProxy (4.7, 912 reviews): reviewers call it rock-solid and nearly maintenance-free, trusted to run quietly under heavy traffic.
• Progress Kemp LoadMaster (4.7, 214 reviews): trusted for high-availability balancing reviewers describe as virtually maintenance-free.
• F5 NGINX (4.6, 113 reviews): trusted for high performance and availability during peak traffic, plus SSL termination and routing.
• AWS Elastic Load Balancing (4.5, 96 reviews): trusted inside AWS for automatic failover across availability zones.
• Cloudflare Application Security and Performance (4.5, 743 reviews): trusted as an all-in-one edge layer, though it is broader than a pure load balancer.

For enterprise SaaS practitioners, which platform earned your trust in production? And did trust come from uptime, failover behavior, or how it handled your worst traffic day?

Hey G2 community, I've been going through load balancing options to get insights on what is the best option when you need something scalable now but don't want to over-engineer the architecture too early; and wanted to share what I found. Would love to hear what others went with and whether it held up as things grew.

What I'm hoping to find: Something that handles real traffic growth without constant tuning, has predictable pricing, works with containers or auto-scaling, and doesn't require a rearchitect the moment the product takes off.

Here's what the reviews are pointing to:

• HAProxy: free, low resource overhead, zero-downtime reloads; reviews from small teams consistently describe it as something you configure once and stop thinking about.
• Traefik: service discovery is automatic when new containers come up, no config update needed on each deploy; Docker and Kubernetes integration described as genuinely easy to start with.
• AWS Elastic Load Balancing: automatic scaling and no capacity management; LCU pricing is harder to predict at early traffic levels but convenient if you're already on AWS.
• Cloudflare Application Security and Performance: warmest reviews from smaller teams; free tier covers enough that many don't need to upgrade early, and DDoS protection is included alongside traffic distribution.
• F5 NGINX: open source with low memory and high concurrency; community documentation is strong.

For teams that started simple and scaled fast, which of these held up without requiring a rearchitect? And at what point did you feel like you'd outgrown what you started with?
