Opensolr offers four hosting tiers, each designed for a different stage of growth. Whether you're running a side project or powering enterprise search for millions of queries, there's a plan that fits.
Shared Solr
Multiple customers share the same server. Think of it like an apartment building — everyone has their own locked unit, but you share the building's resources.
- Lowest cost entry point
- Indexes are fully isolated — your data is private and secure
- Ideal for development, testing, and normal production traffic
- In rare cases, a "noisy neighbor" (e.g., heavy bot traffic on another index) may temporarily affect performance — we monitor for this and can relocate your index if needed (a few minutes of downtime to switch)
Shared Resilient Cluster
Multiple dedicated servers working together, but resources are still shared across customers. Think of it as two apartment buildings connected by a bridge — more room, better infrastructure, same shared model.
- Load-balanced across multiple machines with replicas
- Handles heavy traffic much better than a single shared instance
- Bot traffic still counts toward your bandwidth, but the performance impact is significantly lower
- Great for customers who need higher throughput without the cost of a fully private cluster
Dedicated Standalone
One machine dedicated entirely to you. Like owning your own house — no shared walls, no noisy neighbors, just your workload.
- Complete resource isolation — CPU, RAM, and disk are all yours
- Stable, predictable performance with zero interference from other users
- More affordable than a full cluster, far more private than shared
- Perfect for production workloads that need consistent response times
Dedicated Cluster
A full cluster of multiple dedicated machines, exclusively for you. This is the enterprise tier — your own private data center with built-in redundancy.
- Multiple servers (master + replicas) all working for your workloads only
- Create any number of Solr indexes inside your cluster
- Built-in replication, load balancing, and failover
- Scalable — add more nodes as your traffic grows
- Multi-region deployment available
- Ideal for mission-critical applications, high-traffic platforms, and corporate-grade search
Side-by-Side Comparison
Common Questions
Can I host multiple sites inside one Dedicated Cluster?
Yes. A Dedicated Cluster is your own private environment. You can create as many Solr indexes as you need inside it — one per site, one per application, or however you want to organize your data.
Can another customer's traffic affect my performance on Shared?
It's rare, but possible. We actively monitor all shared instances and will relocate your index to a quieter server if needed (a few minutes of downtime to switch hostnames). For guaranteed isolation, choose Dedicated Standalone or Dedicated Cluster.
Is there any security concern on shared plans?
No. Every Solr index is fully isolated regardless of the hosting tier. Other customers cannot access, read, or modify your data. Shared only means system resources (CPU, RAM) are shared — not your data.
What if my servers are in a different region than the Solr cluster?
The only impact is network latency, typically around 80–130ms for cross-region connections. You can easily test this during the free trial. In most cases, performance is comparable to dedicated unless you're under extremely heavy load.
