Managed Apache Solr hosting. You keep the schema, we keep it running.
Create an index in seconds, pick the Solr version and the country it runs in, and get a URL you can query straight away. Schema, solrconfig, synonyms and stopwords stay yours, editable in the browser. The JVM, the operating system, the disks, the replication, the backups and the 24/7 monitoring underneath are ours — and always have been, since 2011.
Regular search is free forever — a full index, no credit card, no expiry date.
Solr, without the part of Solr that keeps people awake.
Running Apache Solr yourself is not the search work — it is everything around it: heap sizing, garbage collection, segment merges eating the disk at 3am, an OS upgrade that breaks the service script, a replica that silently stopped following. That list is ours. The list that actually decides whether your search is any good stays yours.
You control
In the browser, with no ticket and no waiting.
- schema.xml and solrconfig.xml — edited in place or uploaded, then reloaded onto the live index. Configuration
- Synonyms, stopwords, protwords and every other analyzer resource file
- Fields and field types, including copyFields and dynamic fields. Defining new fields
- Queries — the full Solr API, edismax, faceting, highlighting, grouping, kNN vectors
- Relevance — field weights, minimum match and phrase boosts. Search tuning
- Which results win — pin or bury specific documents. Query elevation
- Who gets in — HTTP auth credentials, IP allow-lists, API keys, team members
We run
Around the clock, whether or not you notice.
- The Solr install itself — version, patches, service supervision, restarts
- The JVM — heap, garbage collection, thread pools, the settings nobody enjoys tuning
- The machines — Linux, kernel updates, disks, capacity, hardware failure
- The network edge — TLS certificates renewed automatically, the Solr port never exposed to the internet
- Replication between master and replicas, and the load balancing in front of them
- Backups — scheduled, off site, and restorable by you from the control panel. Backup and restore
- Monitoring — every node checked continuously, with automatic recovery before you write a ticket
Pick the Solr version. Pick the country. Both at index creation.
Most hosted search runs one version in one place and calls it a platform. We run 3.6 through 9.6 side by side in 9 countries, because a ten-year-old application that pins an old Solr deserves to keep working, and a new one deserves vectors. This table is generated from the live server list, so it is what you will actually see in the Add New Index dialog right now.

Fifteen years of “we needed this once”, all in one place.
Everything below is included on every index, on every plan — there are no add-ons to buy and nothing that unlocks at a higher tier. Full walkthrough in the platform documentation.
Create, clone and delete indexes
An index is live seconds after you click, with its URL and credentials shown on the spot. Clone a working one into a staging copy — data, schema and config — or into a different country entirely. Creating indexes
Schema and config editor
Edit schema.xml, solrconfig.xml, synonyms and stopwords in the browser, or upload them from your machine. Save the file, hit Reload, and the change is live on your index — no ticket, no deployment, no shell. Configuration
The real Solr Admin UI
The stock Apache Solr admin interface, on your index, behind your credentials — query builder, analysis screen, schema browser, plugin stats. Nothing hidden from you. Open the Admin UI
Reload, commit, optimize
The operations that normally need shell access are buttons, and none of them restart anything else on the machine. Index tools
Query analytics
What people searched for, what returned nothing, how long it took, how much traffic it moved. The zero-result list alone is usually the fastest relevance win available. Analytics
Error audit
Seven days of Solr errors, searchable, in the control panel — the difference between “search is broken” and “this one malformed query is broken”. Error audit
Backups you can actually restore
Scheduled and on demand, stored off the machine, restorable to the same index or a different one — and downloadable, so a copy can live somewhere we do not control. Backup and restore
Access control
Per-index HTTP Basic auth, IP allow-lists, scoped API keys and two-factor authentication on your account. Your index answers over HTTPS behind your own credentials; the Solr port itself is closed to the internet. Security
Teams
Invite colleagues or a client's developer, give them the indexes they need and nothing else, and take it back when the project ends. Teams
A REST API for all of it
Every action above — create an index, push documents, upload a schema, start a crawl, take a backup, manage replication — is also an authenticated HTTP call, so your CI can do it. API reference
An empty index is the easy part. Filling it is where hosting usually stops.
Most Solr hosts hand you a URL and wish you luck. Four ways in are already built, and all of them are included with the hosting.
Give us a URL
The built-in web crawler indexes your whole site on a schedule — JavaScript-rendered pages, PDFs, Office documents, sitemaps and all. No code on your side whatsoever. Web crawler guide
Drupal or WordPress
Two free official Drupal modules and a free WordPress plugin, all maintained by us. Install, connect, index — multilingual, Commerce and WooCommerce included. Drupal · WordPress
Push JSON from your own code
Any language, any framework: send documents to the ingestion API and query them back as JSON. Laravel Scout, LangChain, LlamaIndex, Haystack and MCP drivers exist if you want a shortcut. Data ingestion API
No search UI yet? Use ours
Every index comes with a hosted, responsive search page you can send visitors to or embed — complete with facets, highlighting and analytics, and hybrid AI search if you enable it. Embed the search UI
Start on a shared environment. Move when the traffic says so, not before.
The same control panel, the same API and the same Solr drive all three — moving up a tier changes what the index runs on, not how you work with it.
Shared
Your index on a managed multi-tenant Solr server, isolated by core, credentials and firewall rules.
- Live in seconds, no provisioning wait
- Free forever to start, no credit card
- 9 countries to choose from
- Every control-panel feature included
Dedicated
A Solr server of your own: your version, your sizing, your region, no neighbours on the machine.
- Any Apache Solr build you need
- Sized to your index and your traffic
- Region chosen for latency or residency
- Server and JVM tuned to your workload
Resilient cluster
One master for writes and multiple read replicas behind a load balancer, replicating continuously.
- Reads survive the loss of a node
- Indexing never competes with search
- Replicas added as traffic grows
- Multi-region replication available
Fifteen years of production is the only benchmark that counts.
Opensolr has been hosting Apache Solr since 2011, for agencies, universities, publishers, manufacturers and public institutions — some of them on the same index for a decade. Every node in the fleet is checked continuously and recovered automatically, which is why most incidents end before anyone writes to us about them. Replicas keep serving reads when a machine goes away, backups live off the machine they came from, and TLS certificates renew themselves.
Support is ours, not a reseller's and not a chatbot's: the people who answer are the people who run the servers and wrote the platform. When something is our fault we say so, and when your schema is the problem we will tell you that too — usually with the fix attached. Talk to us · Security & Trust Center · Service status
Have a Solr index running in about a minute
Create an account, pick a version and a country, and start pushing documents. Regular search is free forever, so there is nothing to cancel if you decide it is not for you. Prefer to see it working first? Watch the demo or try the live sandbox.
