The short version

  • Each has a real cost: Apache Solr xML-heavy configuration and a developer experience that feels dated beside newer engines; Soketi maintenance has effectively stalled: the maintainer has said time is severely limited, releases are infrequent, and the community has been discussing whether the project is abandoned, which means security fixes may not arrive.
  • They diverge on capability: Apache Solr covers Lucene-based indexing, Soketi covers Pusher protocol compatibility.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Apache Solr

  • Library, archive and catalogue search where faceting is centralnot Soketi
  • Long-lived enterprise deployments valuing stability over noveltynot Soketi
  • Search requiring precise, explicitly configured relevance tuningnot Soketi

Soketi

  • A Laravel application that already uses Echo and wants to stop paying a hosted realtime providernot Apache Solr
  • Realtime notifications or presence indicators where data must not leave your own infrastructure for compliance reasonsnot Apache Solr
  • A local or CI environment that needs a Pusher-compatible server without hitting a paid accountnot Apache Solr
  • A high-connection-count application where hosted per-connection pricing has become the largest line in the infrastructure billnot Apache Solr

Where each one falls short

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

Apache Solr

  • XML-heavy configuration and a developer experience that feels dated beside newer engines
  • SolrCloud depends on ZooKeeper, adding a component Elasticsearch removed years ago
  • Smaller mindshare now, so newer tutorials, hiring and integrations favour Elasticsearch
  • Considerably heavier than a purpose-built application search engine

Soketi

  • Maintenance has effectively stalled: the maintainer has said time is severely limited, releases are infrequent, and the community has been discussing whether the project is abandoned, which means security fixes may not arrive.
  • Dependency drift on Node and uWebSockets.js will eventually force you to fork or migrate, and that cost is unbudgeted at the point you adopt it.
  • There is no commercial support to buy, so a production incident at three in the morning is entirely your problem with no escalation path.
  • Scaling beyond a single node needs Redis and careful configuration, and getting presence channels correct across nodes is a genuine source of subtle bugs.
  • It implements the Pusher protocol rather than tracking it, so any protocol feature Pusher adds later will not appear, and the compatibility guarantee slowly decays.

Answered from the vendors’ own pages

Apache Solr: Is Apache Solr free?

Yes, open source under the Apache Software Foundation.

Soketi: Is Soketi still maintained?

Barely. The maintainer has stated that available time is very limited and releases have been sparse; treat it as community-maintained.

Apache Solr: Solr or Elasticsearch?

Both are built on Lucene. Elasticsearch has the larger ecosystem and a friendlier API; Solr is very mature and strong on faceted search, and remains common in library and catalogue systems.

Soketi: Do I need to change my client code?

No. Pusher client SDKs and Laravel Echo work by changing the host, port and credentials.

Apache Solr: Is Solr still maintained?

Yes, actively, as a top-level Apache project.

Soketi: What does it cost?

Nothing in licence fees. It is MIT licensed; you pay for the server it runs on.

Soketi: What are people moving to?

Laravel Reverb for Laravel applications, and Sockudo, a Rust reimplementation, for others.
