This is the final installment — a complete selection guide for when your project outgrows edge-tts. What are the 31 TTS engines and services on the market, and how do you choose among them?</p> <p>We organize the selection landscape into three layers: <strong>free open-source engines</strong> (run locally, zero licensing cost but with GPU deployment overhead), <strong>free cloud tiers</strong> (ready out of the box with usage limits), and <strong>paid services</strong> (ready out of the box + SLA + advanced capabilities). These are not strictly hierarchical — an open-source engine on self-hosted GPU can be cheaper long-term than paid cloud, while cloud services offer convenience that self-deployment can&rsquo;t match. The choice ultimately depends on your budget, team capacity, and timeline.</p>
