Flexible and scalable documental database system! **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Mid-Market (51-1000 emp.) **Reviewed Date:** December 22, 2025 **What do you like best about MongoDB?** MongoDB is a highly flexible database system that brings several benefits, including support for document nesting and partial indexing across various fields. It continues to allow for robust aggregations, enabling the use of filters and regex operations. At the same time, MongoDB offers a more developer-friendly approach to viewing and modifying any JSON-type documents. We have choose MongoDB for its inherit flexible and because it scales very well, which is exactly what we need. **What do you dislike about MongoDB?** At times, it can be difficult to determine exactly how much data is being retrieved during an aggregation. Having this information readily available while performing such actions—whether in MongoDB Compass or similar tools—would be a significant advantage for assessing performance concerns and overall efficiency. **What problems is MongoDB solving and how is that benefiting you?** MongoDB serves as the primary database system for our team, handling both the storage and retrieval of business data. We rely on it across all our microservices, organizing different areas of concern by using separate namespaces. ### 10. Flexible Data Storage with Developer-Friendly Experience **Rating:** 4.5/5.0 stars **Reviewed by:** Abhishek C. | Associate Software Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** October 01, 2025 **What do you like best about MongoDB?** MongoDB's best part is the flexibility it gives you as a developer. That schema-less structure makes it super easy to just start building something without overthinking all your tables and relations like you do in SQL. On my last project, we had to handle this dynamic insurance data where the fields weren't fixed at all, and Mongo just handled it perfectly. It's really easy to use, especially if you're already comfortable with JSON, 'cause the documents just feel natural. Integrating it with Spring Boot was smooth too – I didn't have to spend a ton of time configuring things, you basically just plug in the driver and go. Implementation-wise, it's not super heavy compared to some other databases, and scaling with replica sets and sharding works decent once you get the hang of it. For customer support, I've never used the enterprise version, but the community forums and the docs are pretty strong; I usually find answers quick. I use MongoDB a lot for side projects and at work, especially when the speed of development matters more than having a super strict schema.Overall, it just feels modern and fast and developer-friendly. It might not be the perfect choice for every single thing, but for projects where the requirements are always changing, MongoDB really saves you time. **What do you dislike about MongoDB?** Yeah, what I don't love about MongoDB is how the performance can just fall off if you don't stay on top of your indexes. At first everything's super fast, but once your data gets bigger, some queries just start dragging and you realize you gotta spend all this time tuning indexes.And they do have transactions now, which is good, but it's still not as strong or smooth as what you get with a relational DB like Postgres. For stuff where you need really strict consistency, Mongo can feel a little risky sometimes. I also think the aggregation framework has a pretty high learning curve. Some queries that would just be a simple JOIN in SQL end up being these crazy long pipelines in Mongo, and it can get messy. It's a solid tool for sure, but it's definitely not a "set it and leave" kind of deal. You really gotta keep an eye on it and tune things regularly. **What problems is MongoDB solving and how is that benefiting you?** So the main problem MongoDB solves for us is handling all this unstructured and semi-structured data. Like in our insurance systems, all these different partners send over data that's slightly different, with fields that are always changing or totally optional. With SQL it was a huge pain to constantly be altering tables, but with Mongo we just take the JSON and store it as-is, which honestly saves us a ton of time. We can just prototype and push feature super quick without getting stuck on some rigid schema designs. It makes the team way more agile and we don't have to rely on a DBA for every little schema change. Scalability is another area where it really helps. Once the dataset gets huge, we can scale out with replica sets or sharding without a massive rewrite on the code side. For stuff that's really read-heavy, it performs great—once you finally get the indexes sorted out anyway . Overall, it just lets us move faster, handle messy, evolving data, and there's a lot less friction between us backend devs and the whole database structure thing. ## MongoDB Discussions - [The instances where mongodb is not a good choice of primary db](https://www.g2.com/discussions/the-instances-where-mongodb-is-not-a-good-choice-of-primary-db) - 1 comment, 2 upvotes - [What is MongoDB used for?](https://www.g2.com/discussions/what-is-mongodb-used-for) - 3 comments, 1 upvote - [What can MongoDB be used for?](https://www.g2.com/discussions/what-can-mongodb-be-used-for) - 1 comment, 1 upvote - [What will be upcoming interesting features](https://www.g2.com/discussions/50468-what-will-be-upcoming-interesting-features) - 1 comment, 1 upvote - [How do i make the mongoDB use more secure as per the security point of view?](https://www.g2.com/discussions/50427-how-do-i-make-the-mongodb-use-more-secure-as-per-the-security-point-of-view) - 1 comment, 1 upvote ## MongoDB Integrations - [Amazon EC2](https://www.g2.com/products/amazon-ec2/reviews) - [AWS Lambda](https://www.g2.com/products/aws-lambda/reviews) - [Boomi](https://www.g2.com/products/boomi/reviews) - [Elastic Stack](https://www.g2.com/products/elastic-stack/reviews) - [Express.js](https://www.g2.com/products/express-js/reviews) - [Google Cloud Storage](https://www.g2.com/products/google-cloud-storage/reviews) - [MongoDB](https://www.g2.com/products/mongodb/reviews) - [Node.js](https://www.g2.com/products/node-js/reviews) - [Python](https://www.g2.com/products/python/reviews) ## MongoDB Features **Data Management** - Data Model - Data Types - Built - In Search - Event Triggers **Agentic AI - AWS Marketplace** - Autonomous Task Execution - Multi-step Planning - Cross-system Integration **Availability** - Auto Sharding - Auto Recovery - Data Replication **Performance** - Query Optimization **Security** - Role-Based Authorization - Authentication - Audit Logs - Encryption **Support** - Multi-Model - Operating Systems - BI Connectors **Database Features** - Storage - Availability - Stability - Scalability - Security - Data Manipulation - Query Language ## Top MongoDB Alternatives - [Amazon DynamoDB](https://www.g2.com/products/amazon-web-services-aws-amazon-dynamodb/reviews) - 4.4/5.0 (495 reviews) - [Couchbase](https://www.g2.com/products/couchbase/reviews) - 4.3/5.0 (142 reviews) - [Redis Software](https://www.g2.com/products/redis-software/reviews) - 4.5/5.0 (130 reviews)
