Olark
Olark is a long-established, simple-to-deploy live chat tool with a clean chatbox, solid integrations, and strong accessibility certification. The honest tradeoffs are per-agent billing and that many capabilities (cobrowsing, translation, chatbots, visitor insights) are sold as paid add-ons, and it lacks the broader shared-inbox and ticketing depth of a full support suite.
Best for: Small businesses that want an easy, reliable, no-frills live chat widget on their site without a full help desk.
Pricing: Standard is around $29 per agent/mo (less with annual prepay) and Pro is custom-priced. Add-ons run roughly $29-$99/mo each (cobrowsing, translation, visitor insights), which can substantially increase the total per-agent cost.
