What do you like best about the product?

We’ve been using Estuary Flow for 5 months now, and our experience has been consistently excellent. We were up and running in just minutes, syncing CloudSQL for Postgres with MotherDuck effortlessly. The ease of integration was remarkable — no roadblocks, no complexity. What stands out even more is the super-prompt, customer-centric support team, who consistently go above and beyond to ensure success. Their responsiveness makes all the difference, and it’s clear that they care deeply about us succeeding with their great product.

What do you dislike about the product?

Nothing, really. Minor glitches experienced in the first days (while testing our integration) were resolved promptly.

What problems is the product solving and how is that benefiting you?

Estuary Flow is solving the challenge of moving large volumes of commerce data reliably and in near-real time from our operational systems into our OLAP database, reducing the operational overhead for our team.

What do you like best about the product?

I really like the IU, is friendly and easy to understand, also the real-time works as intended, and the best part is the support they have, they respond super fast in the Slack channel and they are always willing to help. To set up a new connector is pretty easy too.

What do you dislike about the product?

Its not a dislike but I may need a few connectors that they don't have yet so Im not sure how I will solve that.

What problems is the product solving and how is that benefiting you?

We were using FIvetran and they don't provide real time, and thats the reason we are testing Estuary right now, as well with the nice pricing.

What do you like best about the product?

The UI/UX is seamless with plenty of free integrations to popular SaaS and PaaS tools and datalakes and datawarehouses. You pay for the volume of data you move, hence yielding a high ROI. Estuary has both cloud and on-prem capabilities, making it an extremely agile platform. On top of that, it is easy to deploy.

We use it daily and periodically to synch sources to lakehouse. Before Estuary we were using a popular integration tool, and we managed to save 10x of our bill for 1 of the source integrations. The CTO helped us cost the data flow, helping to convince our management to make the switch. It has also been highly reliable.

Slack channel provides community and Founder/CTO support, so the team listens closely.

What do you dislike about the product?

Troubleshooting errors when integrations fail. Observability of the data streams could be improved.

What problems is the product solving and how is that benefiting you?

The main problem it helped solve was reliability and cost.

What do you like best about the product?

- It offers support for a wide range of connectors. And if you don't find one you need—as was my case when comparing different EL tools—the team can build it for you. In my case, they implemented it within a couple of months.

- It's reliable—you can trust that what you see on the other end (e.g., your DWH) is accurate and consistent.

- The team's support is top-notch. Honestly, nothing compares to what you get with them. They're close, proactive, and genuinely invested in making things work for you. Truly a terrific experience!

- The pricing is transparent and feels fair, especially when you weigh the value you get against other competitors.

What do you dislike about the product?

- At first glance, it can look like a slightly more complex tool—and it may be, especially for someone with a purely business background. But that's only because it's built to give you more flexibility and options. Once you understand the concepts and configurations, you can actually leverage them to improve your data flows.

What problems is the product solving and how is that benefiting you?

Estuary helps me move data from A to B—or even from one to many—at the sync frequency I choose, and it does so reliably. It saves me from having to build and maintain custom scripts or connectors myself.

What do you like best about the product?

I really like Estuary Flow. The tool works well and it is very fast. Setting up pipelines is simple and quick.
Their support is excellent. They always reply fast and are very helpful.
I also like that it can handle both real-time and batch data in one place, and it has many connectors ready to use.
Overall, Estuary Flow is reliable, easy to use, and supported by a great team. I strongly recommend it.

What do you dislike about the product?

It takes some time to understand all the features at first.

What problems is the product solving and how is that benefiting you?

Replicating multiple databases into our DWH

What do you like best about the product?

The Estuary is quite good. We transfer huge amounts of data from MongoDB to our warehouse and it's super smooth.
And yes, there were issues, but their support is equally good, and they solve everything quickly.
Very easy to integrate
We use it daily (in-fact it's always on)

What do you dislike about the product?

Cost is slightly on a higher side.
So we have connected, MongoDB but we haven't connected Google Sheets, since for each connection they charge seperately.
So for Google Sheets, we use something else.

What problems is the product solving and how is that benefiting you?

Getting NoSQL data into SQL based warehouse

What do you like best about the product?

I've been blown away by the speed and helpfulness of Estuary's support.

What do you dislike about the product?

There's a bit of a learning curve with the UI. I felt compelled to ask for help for simple things when initially getting set up.

What problems is the product solving and how is that benefiting you?

I'm able to get our biggest and most mission-critical dataset at a fraction of the cost of the tool I was using previously.

What do you like best about the product?

It's so easy to set up connectors to any of my applications and databases and replicate that data in real-time. Not only that, but I only need one connector per source but can send that source to multiple destinations.

What do you dislike about the product?

Sometimes the documentation can be a bit hard to follow for more complex connectors, but can typically figure it out within a few minutes.

What problems is the product solving and how is that benefiting you?

It helps replicate data in real-time without it being difficult to set up, manage the infrastructure, or cost similar to the likes of Fivetran

What do you like best about the product?

The Pre-Sales Process:

The Estuary team was very responsive, offered great support when it came to explaining what the product is good for and cases where it is not yet capable of ticking some boxes. The honesty and straight-forward approach was much appreciated and unusual in the space. Everybody we interacted with was very hands-on and had deep technical knowledge so answers came quickly in short timeframes and deadline pressures, and in cases where use-cases were complex, we were offered solutions and workarounds tailored to our needs.

The POC Process

Getting access to, and implementing the tool was very easy and efficient. Most of the connectors we required were already available and we were given clear information about which ones were (importantly) on the roadmap with timelines, making it easy to build trust. There were really cool additional features we made use of, such as Terraform compatibility and a command line tool, so we could spin up pipelines repeatably and reliably with a little bit of initial research around these features.

The Sales Process

The Estuary product was far more affordable than other products when it came to our use-case of tall narrow tables with many rows, since they have a Data Ingress/Egress based billing. This worked far better for us than other tools which take a row-based approach to billing, despite our total table sizes being comparatively small. We felt they partnered well with us and helped us find ways for us to do things more efficiently and had our best interests at heart, and it made for a mutually beneficial business relationship.

The Tool Itself

Estuary Flow has been a reliable tool, a real data/technical person's tool. The basics are simple to set up, but it does not preclude the ability for you to customize pipelines. It is very extensible. The architecture is robust and scalable and we have used it reliably for about a year with very few issues.

The Support

This is a very important area and Estuary have delivered on this in a stellar way. On the few occasions that we have had minor issues - Support from the team was very responsive; offering updates, feedback, timelines and solutions in real-time and really giving us the kind of peace of mind we need, at almost all hours. In some cases, where it was sensed that there may be misunderstandings; , they were happy to dig in on our behalf to sort urgent matters out quickly, . They maintained a great level of friendly professionalism and there was never a sense of apathy towards our needs, which can be common with some other data pipeline tools out there (especially the really big ones with heavy support processes and protocols, sending screenshots back and forth)

What do you dislike about the product?

There are almost no down-sides besides the fact that they are still building their number of connectors up to a number that rivals other data platforms (but cover most of the important connectors).

I would say that some of the terminology relating to pipeline components can be a bit confusing at first, but this is also because every data tool names things differently, so this is also more of an industry-wide issue as opposed to an Estuary-specific. Reading through the documentation a couple of time will generally orient you well.

What problems is the product solving and how is that benefiting you?

We are using it for streaming replication of our transactional databases to our analytics warehouses. We also use the tool to ingest data from third-party tools and applications to get an integrated view of our data in our warehouse.

What do you like best about the product?

Estuary is easy to configure not just in the UI, but also maintain using their flow documentation specification using CI/CD processes. This means you can do a baseline configuration in the UI and then immediately push that to your programmatic processes. The team is also extremely easy to engage with on their Slack.

What do you dislike about the product?

Estuary does have a small barrier to entry for configuration of your own buckets to store state as compared to other products on the market. I believe overall this is better for customer security.

What problems is the product solving and how is that benefiting you?

Data movement for all aspects of the business; while also driving down latency to ensure the ability to use that data for any use case. Usually real-time systems such as Estuary are cost prohibitive either via engineering time to maintain a custom solution or other traditional ETL tools which are much more focused on locking you in to their system, rather than providing value.
