Sign up with an email address and a password. There is no card form, no trial countdown and no end date. Your index stays online for as long as you use it.
Opensolr is free, and stays free
The Opensolr free plan is free forever. It is not a trial: there is no countdown, no expiry date and no card. You sign up, you get a working Opensolr Index, and you keep it for as long as you use it. If you outgrow the free limits, you can move to a paid plan — but nothing forces you to.
How it works
Getting started takes about 30 seconds:
What's included
These are the current free plan limits, read live from your account package:
| 1 Opensolr Index | Fully managed, on shared infrastructure. |
| 19.5 MB disk space | The size your index is allowed to reach on disk. |
| 102.4 MB traffic / month | Search and API traffic in and out of your index each month. |
| Full Solr API | Standard Apache Solr. Any Solr client library works, unchanged. |
| WordPress & Drupal | Our free search plugins for both, with facets and autocomplete. |
| Web Crawler | Included on this plan. |
| Backups | Not on the free plan — available on paid plans. |
| Search analytics | Included on this plan. |
| AI requests | Every plan includes 500 AI requests a month. What each plan can use them for: pricing and API Quota. |
Need more room? Every part of a plan can be raised on the pricing page.
Who is this for?
- Developers prototyping an application that needs real search
- Small sites that want proper search without running a Solr server
- Teams evaluating managed Solr as an alternative to self-hosting
- Students and researchers who need a reliable search backend
- Anyone curious about what Opensolr can do, at no cost and no risk
Keeping your index
The plan never expires, but an abandoned index can be cleaned up. This is the only rule that can cost you an index, so it is worth knowing:
Bottom line: use your index and it stays. You will never be charged, and you will never be cut off for a date on a calendar.
