In their own words
Radioso
Radioso provides open-source AI agents for support tickets, help-center answers and lead qualification. Agents can use policies and help-center content for routine work such as returns and escalations, call tools, trigger webhooks, run multi-step routines and hand difficult conversations to people with context. Answers can cite uploaded documents and knowledge shared across channels. Assistants are reachable through Slack, an embedded website widget, public chat, REST API, SDK and MCP server; in Slack, users can mention @Radioso or send a direct message. Radioso runs in its cloud or on customer-operated infrastructure using the customer’s model keys. The Open source plan costs nothing, includes all product features and supports self-hosting. Radioso says ingested content, conversations and prompts are not used to train its own models. Radioso Cloud uses Google Cloud Platform in an EU region and PostHog EU Cloud for analytics, while configured AI providers may process prompts and retrieved context primarily in the United States. Security measures listed include encryption in transit, access controls, audit logging and least-privilege practices.
Vapi
Vapi is a voice-call platform available on the web and iOS. It supports inbound and outbound calls, human handoff, concurrent calls, and custom phone numbers. The usage-based No Success Package is listed at free and includes $5 in starter credits, one Vapi phone number, four concurrent calls, and full platform access. Core costs $29 a month, billed monthly, and includes five phone numbers, 10 concurrent calls, 30 days of raw data retention, and email support. Pro costs $999 a month, billed monthly, and includes 10 phone numbers, 30 concurrent calls, 180 days of raw data retention, RBAC, ZDR, and a 99% uptime SLA. Premier uses custom pricing; its listed options include custom phone-number counts and custom RBAC, ZDR, and SSO, with dedicated SIP available. The service listing says there is no free plan, although the No Success Package is presented at no cost with starter credits. Plan allowances vary, so the listed overall concurrent-call figure of 10 is not the allowance for every package.
