The short version

  • Each has a real cost: Arnica per-identity pricing ($25-$50/person/year) requires tracking active developers; 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: Arnica covers AI SAST, Soketi covers Pusher protocol compatibility.
  • Prices and features above were last checked on 31 August 2026.

  • A local or CI environment that needs a Pusher-compatible server without hitting a paid accountnot Arnica
  • A high-connection-count application where hosted per-connection pricing has become the largest line in the infrastructure billnot Arnica

Where each one falls short

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

Arnica

  • Per-identity pricing ($25-$50/person/year) requires tracking active developers
  • Overage identity tracking via 90-day PR activity can be unpredictable
  • Free plan limited to weekly updates, requiring upgrade for real-time scanning
  • Advanced add-ons (Image Scanning, AI SAST, Agentic Rules Enforcer) pricing not published
  • On-premises deployment limited to Enterprise tier

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

Arnica: How are identities defined in Arnica pricing?

Identities are any users and other contributing entities that contributed code and/or had PR activity during the last 90 days. This ensures billing matches active developers.

Source
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.

Arnica: What is the annual discount?

Annual prepayment offers approximately 17% savings versus monthly billing. Core Business annual is $300/identity versus $360 for monthly.

Source
Soketi: Do I need to change my client code?

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

Arnica: Can I cancel or downgrade Arnica anytime?

Yes. Subscriptions can be cancelled or downgraded at any time. Overage identities receive automatic protection with true-up invoicing.

Source
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.
