Thoughtly Alternative: SIP on All Plans, Manual LLM Selection & Voice Widget

Thoughtly has a clean no-code builder and a low starting price - but SIP trunking is Enterprise-only, LLM selection is auto-managed (you can't manually pick your model on standard plans), and there's no website voice widget. VoiceInfra fills all these gaps while keeping pricing competitive.

WHERE THOUGHTLY SHINES

Clean No-Code Builder at an Accessible Price Point

Thoughtly offers a good no-code builder, multi-channel support (voice + SMS + email), native CRM integrations with write-back, and a low starting price with a free tier available. For simple sales and outbound use cases on Twilio, it works well.

WHERE THOUGHTLY FALLS SHORT

Auto-Managed LLM, Enterprise-Gated SIP, No Voice Widget

Thoughtly uses multiple AI models (OpenAI, Anthropic, Google, Mistral AI) but auto-selects them - you can't manually choose on standard plans. SIP trunking is Enterprise-only; standard plans are Twilio-dependent. No website voice widget. The platform is primarily sales and outbound focused. AppSumo users have reported hidden pass-through carrier fees.
