In their own words
Rapida AI
Rapida AI is an open-source platform for building and operating voice AI agents across phone, web, WhatsApp and SIP. It supports speech processing with voice activity detection and noise cancellation, knowledge retrieval, language-model routing and live call transfer. Teams can bring their own speech-to-text, text-to-speech and language-model providers or route between them without rewriting application logic. Listed integrations include Twilio, Vonage, Exotel, Asterisk, OpenAI, Anthropic, Google Gemini, Deepgram, ElevenLabs, Azure and AWS. Agents can call HTTP endpoints during conversations and sync data from Notion, GitHub, HubSpot and Jira. Rapida provides session traces, transcripts, call monitoring, handoff visibility, request and webhook logs, and debugging context. It offers managed cloud or self-hosted deployment. The maker says self-hosting keeps audio, transcripts and customer data on the user's infrastructure; setup requires Docker and at least 4 GB RAM for Voice Only, or 8–16 GB with the knowledge base. Launch is free. Scale costs $500 a month, Grow costs $2,000 a month, and Enterprise pricing is custom.
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.
