Easy Production Debugging with Clean Dashboards and Reliable Monitoring **Rating:** 4.5/5.0 stars **Reviewed by:** Aniket K. | monday.com Full stack developer and IC, Information Technology and Services, Small-Business (50 or fewer emp.) **Reviewed Date:** July 23, 2026 **What do you like best about AppSignal?** AppSignal is easy it is to find and understand production issues. Whenever an error comes in recvied email notify, I first check AppSignal logs and error details to understand what actually happened before starting the fix. It saves a lot of time because I don't have to search through multiple log files. The dashboard is clean like chart view, and it is easy to see exceptions, performance issues, and request details in one place. We use it regularly to monitor our Node.js applications, and it helps us identify the root cause much faster. The setup was also simple, and once it is configured, it works reliably in the background. Also we can even integrate with github **What do you dislike about AppSignal?** The tool works well overall, but I would like to see more customization in dashboards and alerts. Sometimes I need to click through multiple pages to get all the console logs I need. **What problems is AppSignal solving and how is that benefiting you?** AppSignal helps us monitor our production application and quickly identify issues when something goes wrong. Instead of checking different log files manually, I can see the error details, stack trace, and related logs in one place. This makes it much easier to understand why an issue happened. We also use it along with GitHub, so it is easier to connect application errors with code changes. It helps me debug faster, reduce downtime, and fix production issues with less effort. Overall, it saves time and gives better visibility into the health of our application. ### 2. Extensive Monitoring, Quick Setup **Rating:** 4.0/5.0 stars **Reviewed by:** Luuk V. | Software Developer, Mid-Market (51-1000 emp.) **Reviewed Date:** July 23, 2026 **What do you like best about AppSignal?** I appreciate the communication via support and sales at AppSignal, because they always approach in a friendly manner and are open to feedback and thinking along. The error monitoring is the most valuable for us and quickly provides insight into exceptions and incidents in production. The logging part, especially the S3 integration for long-term storage, has helped us meet compliance requirements. The integration with Slack is great, because alerts and incidents come in automatically, allowing our team to respond immediately. The user-friendliness during the initial installation was impressive; the manual was clear and we were set up within a day. Later expansions like frontend monitoring also went smoothly. **What do you dislike about AppSignal?** The biggest area for improvement for us is in the new MCP integration. It is very promising, but still a bit slow. Also, the UI around logs could use another iteration. **What problems is AppSignal solving and how is that benefiting you?** I use AppSignal for central monitoring of our apps. It provides value by bringing together Rails backend and frontend monitoring, with errors and performance insights. The S3 log integration helps with compliance requirements. It ensures quick incident resolution with context and is well integrated into workflows. ### 3. Reporting and Error Tracking Needs met **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Real Estate | Small-Business (50 or fewer emp.) **Reviewed Date:** July 23, 2026 **What do you like best about AppSignal?** The reporting feature and the ability to generate graphs outlining performance and error counts within a time period. This allows us to better track overall performance of the application on a monthly basis for our internal reporting. Also the ability to filter errors based on last deploys to drill down where an issue may have been caused. This has made it easier to identify which deploys may have been problematic and saves us time combing through previous unrelated deploys. I also appreciate the integration available with Asana. This has saved time in creating tickets for errors rather than having to create these manually. With a click, the task is created for me in and I can triage and assign accordingly. **What do you dislike about AppSignal?** I find that the UI can be a bit clunky and not as user friendly. For example, the Charts and Samples for specific errors can be hard to segment and gather additional details on. **What problems is AppSignal solving and how is that benefiting you?** AppSignal is helping us record our errors and track our application performance across various environments. This has benefitted us as we now have a centralized application where our errors are logged and stored for us to refer back to. The addition of the Asana integration has made things even easier to track and log as we triage these issues to be resolved. Additionally the reporting feature allows us to track error counts over tie to ensure that our application is behaving as expected. ### 4. Effortless Monitoring with Intuitive UI **Rating:** 4.5/5.0 stars **Reviewed by:** Roy v. | Small-Business (50 or fewer emp.) **Reviewed Date:** July 31, 2026 **What do you like best about AppSignal?** I like AppSignal because the user interface is great and integration is simple. I can easily find what I'm looking for, and finding bugs in our source is easy based on the information given by AppSignal. I can easily see what issues are the most urgent. I particularly like the 'what happened at this time?' feature. The initial setup of AppSignal was very easy. **What do you dislike about AppSignal?** I'm astonished that there isn't a simple export feature for logging. Also I would love to have Android integration so we can ditch Sentry. **What problems is AppSignal solving and how is that benefiting you?** I use AppSignal for monitoring errors, performance, server stats, and logging in our Ruby on Rails apps. It helps me find bugs easily and prioritize urgent issues. ### 5. AppSignal: Powerful and Easy to Integrate **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User | Mid-Market (51-1000 emp.) **Reviewed Date:** July 30, 2026 **What do you like best about AppSignal?** I find it very good that AppSignal is easy to set up. The default settings are excellent and provide a good overview right away. If I'm particularly interested in certain areas, I can adjust and refine them. It's great that I can handle both error and performance monitoring within one software without needing multiple tools. The ability to consolidate my error and performance monitoring and have pre-configured log options is very helpful. Status pages for monitoring uptime are practical for receiving notifications when the application is not accessible. The guides are especially good for Ruby and integration into Ruby on Rails, making the setup a breeze. **What do you dislike about AppSignal?** I am completely satisfied. **What problems is AppSignal solving and how is that benefiting you?** I use AppSignal to monitor our Ruby on Rails application. It shows bugs and issues, enables performance monitoring, and helps improve slow pages. The setup is easy, the default settings are good, and I can save logs and track uptime. ### 6.

It is hard to find a good balance between getting notified of major issues and getting spammed with alerts for a bunch of small things **What problems is AppSignal solving and how is that benefiting you?** I find a lot of edge case bugs that I would never have found in testing as well as alerts to major issues that slipped through ### 7. Effective Error and Performance Tracking + AI Support **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User | Small-Business (50 or fewer emp.) **Reviewed Date:** July 31, 2026 **What do you like best about AppSignal?** I find the MCP for Errors and Performance really helpful, especially since samples came into play for Errors. It allows me to automate routines for Error Investigations and Performance degradations. Errors, Monitoring, and Performance, and AI Support via MCP are really good. **What do you dislike about AppSignal?** I find that logging will never be needed for me because my provider (AWS) already does this well. Also, tracking of metrics seems better handled by providers, and I feel like AppSignal doesn't put much love into it—sometimes even displaying long metrics seems kind of broken. But that's okay for me since the handling of errors, monitoring, and performance alongside their AI support are really good. **What problems is AppSignal solving and how is that benefiting you?** AppSignal gives me error awareness with context and helps me to automate routines for error investigations and performance monitoring via AI. ### 8.

With a single-agent installation, we can conveniently monitor our production deployments for our customers. Automatic resource discovery, connectivity rate handling and baseline comparisons are best while using Appsignal. **What do you dislike about AppSignal?** Its ignore action settings need to be configured carefully since Appsignal will filter all actions in this particular list so that it doesn't get data into Appsignal servers. Enabling it will also not count towards our billing plan so it needs to be handled properly. It isn't a downside but an important consideration which we follow for monitoring our application's performance in Appsignal. **What problems is AppSignal solving and how is that benefiting you?** The major benefit of using Appsignal is its deep dive monitoring capabilities for our customer transaction records so that we can easily carry on with our RCA in case of issues. It effectively captures & aggregates the usage metrics and helps us identify various bottlenecks that are essential for refactoring & reverting changes. We drill down to analyze path issues in application services, database SQL queries and to prevent memory over-utilization/under-utilization. The standalone agent offered by Appsignal is efficient to detect anomalies and carry out uptime monitoring throughout our application runtime. ### 27.

Fantastic APM **Rating:** 5.0/5.0 stars **Reviewed by:** Kenny E. | Small-Business (50 or fewer emp.) **Reviewed Date:** August 12, 2020 **What do you like best about AppSignal?** AppSignal has a lot of options for customizing the data captured but it captures a lot of useful info 'out of the box' too. **What do you dislike about AppSignal?** I don't dislike anything. There are some minor 'missing' features available in similar solutions tho. **Recommendations to others considering AppSignal:** Try it! **What problems is AppSignal solving and how is that benefiting you?** AppSignal lets us trace the performance of requests, monitor basic host metrics and our app's runtime environment, and greatly helps us prioritize performance improvements. ### 29. AppSignal instrumental to scaling our app **Rating:** 5.0/5.0 stars **Reviewed by:** Thimo J. | Mid-Market (51-1000 emp.) **Reviewed Date:** September 04, 2020 **What do you like best about AppSignal?** Adding AppSignal to our app has been crucial in getting it to scale to the level we grew to at the end of the Covid19 lockdown. Because we had to add reservations and checkins/-outs our traffic would increase at least 10-fold. With the help of error logs in AppSignal and detailed graphs of the performance of various parts of our app we were able to remove bottlenecks and end up with a reliable service. Next to this a couple of things where AppSignal stands out: - second to none support. It's their developers themselves show are quickly and clearly answering any questions you may have. It's hard to overstate how nice this is - great documentation - friendly, speedy and beautiful user interface **What do you dislike about AppSignal?** The only thing I'm missing at the moment is a (free) plan to use AppSignal on open source / hobby projects that don't make money. Can't blame AppSignal for this, but it would be nice to have this option. **What problems is AppSignal solving and how is that benefiting you?** The main benefits: - being able to quickly analyse and fix errors in production - find performance bottlenecks - graphs to show decreasing performance over time ### 30. One single platform to manage everything you want in your infrastructure **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Enterprise (> 1000 emp.) **Reviewed Date:** August 03, 2021 **What do you like best about AppSignal?** Anamoly detection and host usage features are my favorites. **What do you dislike about AppSignal?** I felt the User Interface sucks. The screens are overwhelmed with all the options and functionalities stuffed at one single place making it difficult to identify which is where. **What problems is AppSignal solving and how is that benefiting you?** We had app scripts that determine the host usage stats. Based on that we cut our costs or increase the costs of the clients. ### 31. Great monitoring tool for Ruby on Rails applications **Rating:** 5.0/5.0 stars **Reviewed by:** Raimonds S. | Small-Business (50 or fewer emp.) **Reviewed Date:** March 15, 2020 **What do you like best about AppSignal?** AppSignal is very easy to add to your Ruby on Rails applications and out-of-the-box it provides many meaningful metrics both for web requests as well as background jobs. Later we also added several custom events specific to our application and it was quite easy. We also like that it supports JRuby which we use (as some monitoring tools only support MRI implementation of Ruby). Previously we used New Relic and comparing to that AppSignal was easier to use as well as the AppSignal pricing model is much better compared to New Relic. **What do you dislike about AppSignal?** So far we have not had any problems with the service. **Recommendations to others considering AppSignal:** As it is very easy to add to your Ruby on Rails application then start a trial and see if it provides valuable information out-of-the-box. **What problems is AppSignal solving and how is that benefiting you?** We are monitoring the overall throughput of our application (to identify any strange behavior). We have used it to profile specific web requests and improve performance of them (we noticed several slow actions that we didn't know previously). We log unexpected errors and AppSignal provides good way to see individual cases of these errors with corresponding stack traces. It helps to quickly identify if there are any unexpected errors after each deployment. ### 32. They Value Customer Satisfaction Over Greed **Rating:** 5.0/5.0 stars **Reviewed by:** George C. | Innovator, Small-Business (50 or fewer emp.) **Reviewed Date:** March 30, 2020 **What do you like best about AppSignal?** Besides the inherent value they provide, I just want to share a quick scenario. We hired a developer that signed us up for all of these Softwares over a year ago and I thought I had canceled all of them but this past year has been a crazy journey (like I sure so many can relate) and I didn't realize we had not canceled with AppSignal. I'm embarrassed to say that I had only recently due to Taxes and COVID taken the time to catch up on balancing our CC transactions... then realized, after asking the team about AppSignal that no one was using it... Anyways, I reached out to AppSignal and explained our scenario and how we hadn't been using the service for quite some time and Stefan decided to respond and said: "Hi George, that sucks! As if these times aren't hard enough! It looks like you have monitoring requests with us almost until the end of last year. To help you out in these hard times, I have refunded the last 6 month of your subscription. (These will show up in a few days after they are processed by your credit card company). I hope you will stay healthy and bounce back after all this. Thanks for being a customer. Stefan." Thought I would share since not many companies I've had such a great experience with...
