"Powerful tool for automated voice escalation in logistics"
What do you like best about Synthflow?

I’m using Synthflow to automate the escalation of GPS monitoring incidents. I love how easy it is to create custom flows that trigger phone calls in multiple escalation levels (driver → supervisor → manager). The voice quality in Spanish is incredibly realistic, and the webhook support makes it easy to integrate with my Python backend. I also appreciate the speed at which I can prototype and deploy logic. In just one day, I built a fully functional voice escalation system. Highly recommend it! Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

I wish the platform offered a few test minutes by default upon signup to speed up the testing process. Also, it would be helpful to have more documentation or code examples for webhook integrations. However, the support team responded quickly when I asked for help. Review collected by and hosted on G2.com.

"Nice intregration ecosistemm but bad support"
What do you like best about Synthflow?

I’d say the two things I appreciate most about Synthflow are its rich integration ecosystem and its remarkably smooth configuration experience:

1. Seamless, “plug‑and‑play” integrations

Synthflow comes with out-of-the-box connectors for virtually every major data source and service—everything from SQL databases (Postgres, MySQL) and data warehouses (BigQuery, Snowflake) to messaging platforms (Kafka, RabbitMQ), cloud storage (S3, Azure Blob) and even popular SaaS tools (Salesforce, HubSpot). Because those adapters are already battle‑tested, I can spin up end‑to‑end pipelines in minutes, without having to write custom boilerplate or wrestle with OAuth flows. It means less time building “glue code” and more time focusing on the actual business logic.

2. Intuitive, code‑friendly configuration

Whether you prefer a visual drag‑and‑drop canvas or treating your workflows like code (YAML/JSON definitions, CLI-driven deployments), Synthflow handles it beautifully. I love that I can declare my entire DAG in a few lines of YAML—defining tasks, dependencies, retry policies and schedules—then immediately validate and deploy it. The live preview and built‑in linting catch errors early, and I can tweak parameters on the fly without ever breaking the pipeline. That balance between simplicity and power means I’m shipping reliable data workflows faster than ever.

Together, these capabilities let me integrate dozens of systems in a matter of hours and confidently manage complex pipelines—all without getting bogged down in infrastructure or configuration headaches. Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

The one area where Synthflow falls short for me is its support responsiveness. Just last week I ran into a connector error that was blocking a critical data pipeline; I opened a support ticket outlining the exact steps to reproduce, but after several days there’s still no update or ETA on a fix. This delay had a couple of knock‑on effects:

Operational impact: My downstream jobs stayed stuck in a retry loop, which forced me to spin up temporary workarounds and monitor them manually.

Lack of transparency: The ticket remains “open” without any comments—no acknowledgement, no progress notes, and no estimated timeline for resolution.

Self‑help gaps: While the docs cover most “happy‑path” configurations, there isn’t enough guidance for troubleshooting edge‑case failures. When support is slow, I’m left combing through logs and configuration specs hoping to find a clue.

In short, Synthflow’s features and integrations are rock‑solid, but a clearer SLA and more proactive communication from support would make a huge difference—especially when pipeline uptime is on the line. Review collected by and hosted on G2.com.

"Finally, a plug-and-play AI appointment setter that actually works"
What do you like best about Synthflow?

SynthFlow makes setting up AI voice agents ridiculously easy. I had my first outbound appointment-setter built and calling in less than an hour. The interface is clean, the flow builder is visual and simple, and the voice options sound genuinely human. What I like most is how flexible it is — I can connect it to my CRM, Calendly, or Cal.com without hiring a developer. The AI logic and knowledge base options give you control without making it complicated. Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

The only annoying part is the setup of phone numbers and minutes — you need to add credit before testing live calls, and creating verified addresses for countries like Australia can be a bit tricky. It would be great if they offered a built-in simulator or free test minutes for quick voice previews. Other than that, it’s been smooth. Review collected by and hosted on G2.com.

"Effortless Setup and Integration with Powerful AI Calling"
What do you like best about Synthflow?

I find Synthflow's integration with GoHighLevel very beneficial, making my work processes smooth and seamless. The user experience is straightforward and easy to manage, which was a key reason for my choosing Synthflow over other vendors. I particularly appreciate how easy it was to set up, as it was a very straightforward process with no complications. Additionally, the speed to lead feature is incredibly effective; it ensures that new leads are contacted immediately as they come in, which has resulted in my clients seeing excellent results. The AI calling feature stands out as an essential tool, providing efficient communication with leads and contributing significantly to the positive outcomes for my tutoring marketing agency.

"Synthflow - Outbound Agent and campaign setup in only 24 hours!"
What do you like best about Synthflow?

Synthflow provided the most suitable tool for creating a Voice Agent for our very first AI agentic global customer.

Within 24 hours of signing up to Synthflow we have managed to connect it to Hubspot and Zapier to automate campaign triggered Agent Calls.

The agent prompts during agent configuration were straighforward and the selection of voices suited our campaign audience.

We have reviewed many different solutions and this is the best out there for us right now, give it a go! Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

There is an auto-save option instead of a save button for config changes which sometimes crashes if you click through too quickly - what can I say I was eager - but worked around it and it did not pose any real problems to getting a campaign up and running.

"A game-changer for building AI voice workflows"
What do you like best about Synthflow?

I joined Synthflow just a week ago and completed all the courses — and I’m genuinely impressed. The platform makes it incredibly simple to design AI voice workflows without needing to code. The agency functionality is a standout feature — it opens up real business opportunities by allowing you to manage multiple client projects seamlessly. As someone just starting out, this gives me confidence and direction. Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

As a new user, everything has been smooth so far, but I’d love to see more real-world templates or use-case libraries to speed up client delivery. A few more third-party integrations would also make it even better. Review collected by and hosted on G2.com.

"Excellent product"
What do you like best about Synthflow?

What I like the most is the fluency with which the agent handles interventions. The organization of their interventions recorded in a CRM is clearly an advantage over other competitors as it allows for having a schedule and clearly monitoring everything that has been done. Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

There should be a trial, with minutes for people to bring the recommendations others give about Synthflow down to reality, since it's not the same as being told about it and being able to try the service oneself, adjusting it to one's own needs. Review collected by and hosted on G2.com.

"Good Value for Simple Call Automation"
What do you like best about Synthflow?

Its Pretty easy to use and learn and has some great features Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

The service is too expensive.

Furthermore, technical errors are unhelpful; I constantly see vague messages like "Failed to create room" when calls fail. Please implement clearer error messages.

Finally, the free plan is too restricted. We need more test minutes to properly evaluate the high-priced service. Review collected by and hosted on G2.com.

"Very user friendly and time saving."
What do you like best about Synthflow?

I really like how quickly you can create an AI call flow that sounds natural and conversational. The ability to design branching logic for different lead responses makes it feel like a real human agent is handling the call.

The most helpful aspect is the combination of AI-driven voice with structured flow logic. It allows me to automatically qualify leads, book appointments, and capture important details without needing to manually script every single response. Integrations with CRMs and calendars are also a huge time-saver. Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

Right now, the AI can sometimes misinterpret unexpected responses or pause too long, which can make calls feel slightly unnatural. Also, setting up complex branching logic can be a bit tricky until you’re familiar with the interface. Review collected by and hosted on G2.com.
