Gumloop

Pros

  • + Fastest AI-flow building I tested: scrape-summarize-extract agent went up in ~40 minutes, with a model swap as a drop-down change
  • + IT control features are real on Pro (agent-scoped connector policies, shared credentials, usage analytics) and org-wide on Enterprise
  • + Unlimited agents, seats, and teams on Pro from $37/mo — no per-seat tax, unlike most rivals (gumloop.com/pricing)
  • + Hosted scraping node handled a JS-heavy site my plain HTTP attempt failed on
  • + Well funded for its age: $17M Series A (Nexus) and a $50M Series B, with named customers like Shopify and Instacart

Cons

  • - No free plan — 14-day trial only — and the 8% orchestration fee on top of credits makes heavy usage hard to predict
  • - Credit costs vary by node and model; my scrape-heavy flow cost roughly triple the targeted version before I tuned it
  • - Shallow for engineers: no code steps with real package access, no self-hosting (Enterprise VPC only), thin connector breadth versus Zapier/Make
  • - Agent memory is flow-scoped — persistent cross-run context is early despite the self-improving-agent marketing
  • - Pro concurrency caps (5 workflow runs, 25 agent chats) queued my bulk jobs; throughput is not the strong suit yet

Ultravox

Pros

  • + Speech-native model handled interruptions and overlaps without the cascade failure I have seen in STT/LLM/TTS stacks
  • + Mid-call tool execution in my test paused and resumed speech without dead-air gaps
  • + Transparent metered pricing: 30 free minutes then $0.05/min, verified by third-party price tracking in August 2026
  • + Open model weights (fixie-ai/ultravox) allow self-hosting for teams that need model-level control
  • + RAG corpora and custom voices are configuration steps, not build steps

Cons

  • - Acquired by Inworld AI on 1 October 2026 — continuity is promised but the roadmap is unwritten
  • - No free plan beyond the 30-minute allowance; sustained experimentation is paid
  • - Developer-only product: no visual agent studio, no templates for non-engineers
  • - Pay-as-you-go caps at 5 concurrent calls, which queued my parallel test calls
  • - The hosted platform (scheduler, telephony, voice management) is where the value sits, so open weights are not a free substitute
