Firecracker Review: Pros, Cons, Features, and Pricing
Firecracker, developed at Amazon Web Services, is an open-source virtualization software with minimal memory overhead. It is a virtual machine monitor, or hypervisor, that creates and manages microVMs through the Linux Kernel-based Virtual Machine. It's ideal for cloud service providers and developers needing quick, secure microVM deployments, such as those in tech startups or agile development teams. Firecracker's virtualization technology delivers fast boot times and efficient resource use for streamlined microservices.
As a VMM, AWS Firecracker addresses resource allocation and security concerns for DevOps teams and cloud infrastructure departments. In this article, I'll cover Firecracker's features, pros and cons, use cases, pricing, and more to help you decide if it aligns with your operational needs and strategic goals.

Our Review Methodology
How We Test & Score Tools
We’ve spent years building, refining, and improving our software testing and scoring system. The rubric is designed to capture the nuances of software selection and what makes a tool effective, focusing on critical aspects of the decision-making process.
Below, you can see exactly how our testing and scoring works across seven criteria. It allows us to provide an unbiased evaluation of the software based on core functionality, standout features, ease of use, onboarding, customer support, integrations, customer reviews, and value for money.
Core Functionality (25% of final scoring)
The starting point of our evaluation is always the core functionality of the tool. Does it have the basic features and functions that a user would expect to see? Are any of those core features locked to higher-tiered pricing plans? At its core, we expect a tool to stand up against the baseline capabilities of its competitors.
Standout Features (25% of final scoring)
Next, we evaluate uncommon standout features that go above and beyond the core functionality typically found in tools of its kind. A high score reflects specialized or unique features that make the product faster, more efficient, or offer additional value to the user.
We also evaluate how easy it is to integrate with other tools typically found in the tech stack to expand the functionality and utility of the software. Tools offering plentiful native integrations, 3rd party connections, and API access to build custom integrations score best.
Ease of Use (10% of final scoring)
We consider how quick and easy it is to execute the tasks defined in the core functionality using the tool. High scoring software is well designed, intuitive to use, offers mobile apps, provides templates, and makes relatively complex tasks seem simple.
Onboarding (10% of final scoring)
We know how important rapid team adoption is for a new platform, so we evaluate how easy it is to learn and use a tool with minimal training. We evaluate how quickly a team member can get set up and start using the tool with no experience. High scoring solutions indicate little or no support is required.
Customer Support (10% of final scoring)
We review how quick and easy it is to get unstuck and find help by phone, live chat, or knowledge base. Tools and companies that provide real-time support score best, while chatbots score worst.
Customer Reviews (10% of final scoring)
Beyond our own testing and evaluation, we consider the net promoter score from current and past customers. We review their likelihood, given the option, to choose the tool again for the core functionality. A high scoring software reflects a high net promoter score from current or past customers.
Value for Money (10% of final scoring)
Lastly, in consideration of all the other criteria, we review the average price of entry level plans against the core features and consider the value of the other evaluation criteria. Software that delivers more, for less, will score higher.
Core Features
MicroVMs: Firecracker runs lightweight microVMs that start quickly, saving your team time on deployments. This feature is perfect for handling multiple, isolated workloads efficiently.
Fast Boot Times: Firecracker VMs boot in milliseconds, allowing your work to begin almost instantly. This speed is crucial for applications needing rapid scaling.
Low Infrastructure Requirements: Firecracker uses minimal resources, ensuring efficient performance even with limited infrastructure. Your team can run thousands of Firecracker microVMs on a single virtual CPU.
Security Isolation: Each microVM is isolated and has a minimal attack surface, enhancing security for your workloads. This feature helps protect your data from cross-VM vulnerabilities.
API Driven: Firecracker offers an API-driven interface, giving your team control over VM management. It's designed for automation and seamless integration into your workflows.
Minimal Overhead: With Firecracker, you can enjoy virtualization with reduced memory overhead, freeing up system resources for other tasks. This efficiency is key for cost-effective operations.
Ease of Use
Firecracker's user interface might not be the most intuitive, especially for those new to virtualization. It requires you to build kernels and root filesystems, which could slow your team down if they are new to Linux internals and writing in Rust. However, once you're familiar with its API-driven setup, managing microVMs becomes straightforward. The minimalistic design focuses on performance and speed, which benefits those who prioritize efficiency over ease of use. If you're tech-savvy, you'll appreciate the control it offers.
Integrations
Firecracker integrates with Docker Hub, OpenNebula, AWS Lambda, and AWS Fargate.
Firecracker also has an API that allows you to connect with third-party integration tools.
