Last9 Reviews & Product Details

last9's sales/support team was incredibly helpful in setting us up / getting us started using the platform. It has been intuitive and most importantly powerful to use. Has done a great job helping us cut through the massive amounts of telemetry data our system produces, and the insights we've gained from it have already highlighted bugs in our system and helped us identify and resolve outages before they got out of hand.

Last9's high cardinality data features made it stand out from other products we considered. Review collected by and hosted on G2.com.

So far all the features I've personally needed have been there.

Data is stored on and transits through last9 servers, which means for our data privacy requirements we have to sensor user data before we send it to last9. It would be great if we could self host some parts of the software such as specific trace data Review collected by and hosted on G2.com.

Last9 makes it incredibly easy to gain visibility into system health with its well-structured observability features. I really like how the platform emphasizes reliability as a product, helping teams move from reactive firefighting to proactive monitoring. The dashboards are intuitive, setup is smooth, and the alerts are precise without being overwhelming. Review collected by and hosted on G2.com.

The learning curve for new users can be a bit steep, especially if they’re not already familiar with SRE concepts like SLOs and error budgets. Some advanced features could use more detailed documentation or onboarding support. Review collected by and hosted on G2.com.

What I like best about Last9 is how convenient it makes debugging. Recently, I had to investigate an incident across nearly 20 microservices. With Last9, it was easy to search for the exact service I needed and then check the logs to trace the issue. That saved me a lot of time compared to digging through everything manually. The platform itself is pretty easy to use and straightforward to implement, so getting started didn’t feel like a heavy lift. I also find myself using it quite frequently because the features are practical and actually helpful for day-to-day debugging. Integration with our existing setup was smooth, and whenever I’ve needed help, their customer support has been responsive. Another thing I really value is data privacy—after some research, I found that Last9 keeps everything encrypted, which gives me confidence that my company’s data is secure.

Honestly, I haven’t found anything major to dislike. The only small issue I’ve noticed is that sometimes there’s a bit of latency, and occasionally the data doesn’t update right away, so I need to refresh. Review collected by and hosted on G2.com.

What I value most about Last9 is that it truly feels worth the price we are paying. Their pay-for-what-you-use model is transparent and they even worked with us to personalize the experience and bring costs down to a level that suited our needs. The team went above and beyond by staying in touch with us every day during setup and optimization. That level of support is rare, and it really helped us adopt the platform smoothly.

There’s honestly not much to dislike, but if I had to pick one thing, it would be that because Last9 is evolving so quickly, sometimes it takes a little time to catch up with all the new features. That said, their team is very responsive and helps us navigate any changes. Review collected by and hosted on G2.com.

What I really like is how easy it was to get started — the implementation was way smoother than I expected. It plugged into our existing stack without much fuss, so I could actually start using it instead of spending weeks setting it up. I use it pretty regularly, almost daily, because it gives me a quick read on reliability and highlights the issues that actually matter to users. The SLO-first approach makes it super clear what’s important, and the customer support team has been really responsive whenever I’ve had doubts — I’ve always gotten clear answers fast. Overall, it feels like a developer-friendly tool that makes my life simpler. Review collected by and hosted on G2.com.

The only tricky part for me was the learning curve in the beginning. Some of the concepts around SLOs felt a little overwhelming, and I had to spend extra time figuring out the best way to use them for our setup. I also think the docs could use more hands-on examples, which would’ve made implementation even easier. I use it pretty often now, but early on, I found myself not knowing which view to check for certain questions. Support helped when I reached out, but I think a bit more in-product guidance would go a long way. Review collected by and hosted on G2.com.

I am a Associate Developer and need more context on product to enhance my learning. Last9 has been a great helping tool to achieve that where i can see all the flows in multiple microservices, filter them by tima and log levels. I have been using last9 almost daily. It is easy to integrate and is one time process. once integrated i can just add a log in my codebase and i can track the flow in real-time. it also has rehydration that is very helpful and makes it very easy to get logs for a certain time range. Query and send to slack features are also very useful for solving customer support tickets. Review collected by and hosted on G2.com.

The tail logs function is something i have never used. For 20+ microservices, its hard analyse all the logs coming in real time.

Other than that, last9 do what it should do, Give structured logs. Review collected by and hosted on G2.com.

We started using the Log Analytics feature in the Last9 Levitate platform, and the team has been consistently adding capabilities that quickly addressed our needs. I appreciate the transparency into their product roadmap, their availability for quick and responsive support, and the cost-effectiveness of the platform. The diverse integration options also make it very easy to get started without heavy setup. Review collected by and hosted on G2.com.

Since the Log Analytics feature is still relatively new, it currently lacks some of the advanced functionality that larger vendors offer. However, with the pace at which Last9 is building, I believe it can soon reach feature parity while maintaining a much more cost-efficient approach. Review collected by and hosted on G2.com.

The clean interface and proactive alerting make it simple to catch issues before they impact users. Setup was quick, and the platform fits seamlessly into our workflow. Their customer support is responsive and helpful, which makes adoption smooth. We now rely on Last9 almost daily for monitoring and weekly for SLA reviews, and it consistently saves us valuable troubleshooting time. Review collected by and hosted on G2.com.

I’d like more flexibility in customizing alert thresholds and advanced integrations, but overall these are minor compared to the value it delivers. Review collected by and hosted on G2.com.

As a developer in the fintech space, I really appreciate how easy Last9 is to use. The learning curve is minimal — you don’t need to dig through heavy documentation just to get started. The user interface is clean and intuitive, which makes it easy to filter logs, view metrics, and understand system behavior at a glance.

In terms of implementation, it was fairly straightforward to integrate Last9 into our existing observability stack. The platform supports seamless integration with multiple environments and services, which is a big plus in a microservices-heavy architecture like ours.

I use Last9 almost daily, especially during incident investigation or performance monitoring. The real-time analytics and visualizations are extremely valuable for identifying anomalies quickly and reducing mean time to resolution (MTTR). Review collected by and hosted on G2.com.

One thing that can be frustrating is the occasional UI lag or unresponsiveness. Sometimes, the dashboard doesn’t reflect updates properly unless you do a hard refresh or switch screens, which suggests that cache handling might not be optimal. This can slow things down when you're in the middle of troubleshooting an issue.

Also, while the platform has a good range of features, there’s still room for enhancement around session management and auto-refresh stability to improve the overall experience. Review collected by and hosted on G2.com.

Last9 stood out in our rigorous PoC evaluations due to its reliability-first observability model, cost efficiency, and engineering-friendly interface. Their focus on SLOs, reliability scores, and proactive monitoring aligned closely with our operational priorities. What truly differentiates them, though, is how deeply invested their support and customer success teams are—during IPL season when our traffic scaled dramatically on a daily basis, Last9 tuned their infrastructure dynamically to meet our specific needs, something we’ve never experienced with other vendors.

Not much to dislike at this stage. If anything, I’d say the product is still evolving and there are a few integrations and features we’d like to see built out more natively. That said, the team has consistently incorporated our feedback into their roadmap, so we’re confident these gaps will close quickly. Review collected by and hosted on G2.com.
