Frequently asked questions
What is self-managed and what is SaaS?
Lunar.dev's infrastructure, is installed and managed directly within your own cloud infrastructure. This approach ensures that all data related to API calls and their payloads are exclusively managed and stored locally, providing full control over your data with no external exposure.
Lunar.dev's UI Control Plane is a SaaS component (Software as a Service) offering centralized control and visibility. The data shown in the UI includes system telemetry, system usage, and aggregated metrics on API volumes. Importantly, this data sharing aspect of the SaaS offering can be disabled by the customer, offering flexibility in how much information is transmitted and reflected in the UI.
What’s the difference between the free version and the paid versions?
The free version of Lunar.dev provides essential capabilities, including control over API traffic and a single instance of the Lunar Consumption Gateway, along with access to standard Lunar Flows (policies).
In contrast, the paid versions unlock features designed for complex, high-volume environments, with the key differentiator being scalability:
- Scalable Gateway Cluster: The free version is limited to a single instance of the Lunar Consumption Gateway, whereas the paid versions offer a scalable cluster of Lunar gateways. This cluster architecture shares a Redis-backed state across multiple instances, making it ideal for production environments and growing businesses.
- Failover and Load Balancing: The cluster setup ensures robust failover mechanisms and load balancing, enabling traffic distribution across multiple gateways. This guarantees uptime and reliability, even if one gateway instance goes down.
- Premium Flows and Custom Capabilities: Paid tiers include access to advanced, custom-made Lunar Flows tailored for intricate use cases, along with increased volume handling for API calls managed by the system.
These enhancements make the paid versions well-suited for businesses seeking comprehensive API consumption management, with robust scalability and high availability for their production needs.
Will my API calls experience increased latency?
API calls routed through the Lunar.dev's Consumption Gateway experience minimal additional latency. The maximum latency impact observed is only 4ms at the P95 percentile. By leveraging HAProxy and continuous optimizations, it keeps latency overhead to a bare minimum.
For more details, you can review our comprehensive latency and benchmarking analysis and report of how we benchmark.
Is sensitive data stored by lunar.dev?
Lunar is deployed entirely within your cloud environment, ensuring that no API calls or sensitive Personally Identifiable Information (PII) and customer data are routed to our SaaS infrastructure. The data transmitted to our infrastructure solely consists of system heartbeat, configurations, and telemetry information. Get in touch to get more details about our security measures at info@lunar.dev.
Is lunar.dev another middleware in my environment?
We know the build-vs.buy dilemma. We believe leaving API integrations unmanaged equals more technical debt, and similarly, that building your API middleware will cause you exponential maintenance and issues as you scale. In the Beta Version, implementing Lunar requires a simple import of our supported interceptors via SDK and a one-line installation of the Lunar forward proxy. Removing Lunar is also as simple as that. it is just as easy as if it never existed. Read more about it in this post.
Is lunar.dev a SaaS solution?
In addition to our OSS and self-hosted version, you can request access to our beta SaaS version, and inquire more information at info@lunar.dev.
Is Lunar.dev Free?
Yes, lunar.dev released a free open-source version. Lunar.dev will continue to be free for Open Source or educational projects in it's self-hosted option. To inquire more about SaaS and pricing reach out to info@lunar.dev.
What the community thinks about Lunar.dev
“As the API economy matures, it will be interesting to see how this new category of API consumption management evolves to enhance and streamline software development. I recommend technology leaders keep an eye on this evolving space to learn the practices required to finally see the entire API journey.”

Using a tool like this is like outsourcing your API management. It means getting a central location where all the integrations happen. You’re getting a team of experts, and you’re always in the know as to what’s going on in this domain thanks to the management and observability capabilities you’re receiving.

"No one will be managing APIs post-integrations alone in a few years. A solution like Lunar.dev ensures business continuity on another level - downtime, security, costs and even policy enforcement are more easily managed in a unified way. Many teams can benefit from a solution like Lunar."
Ronen Slavin
CTO & Co-founder @ Cycode
"Lunar.dev helped us solve an acute recurring 429 problem in production. What I loved about it was the easy installation and light-weight solution. Lunar helped us reduce Back-off errors by 50% and get to 100% Successful API calls."
Maor Hizkiev

"Lunar.dev is changing the game for consumed APIs in production. I’m happy to see a robust but surprisingly simple infrastructure solution like Lunar, giving developers more autonomy to fix and optimize consumed APIs on the fly."
Amir Shevat
Author of the API book Designing Web APIs: Building APIs That Developers Love
"I've been waiting for a solution like this, that's focused on API consumers, for years! Having implemented resilience mechanisms, I've experienced first-hand many of the traps related to APIs post-integration. Throttling and caching are often basic abilities for internal building, but consider how many developer hours you've dedicated to building and maintaining these, time after time."
Naor Paz
Director of Product @ Firefly
"Consuming 3rd party APIs is often overlooked. An effective unified management solution for outgoing traffic, like Lunar, can save engineering teams costs, time, and solve recurring performance issues."
Drorit Baron
Technical Lead @ Riskified
"The open core nature of Lunar is attractive to me as an engineer. I’ve had to handle so many reliance building issues on my own, chaching throttling and building scrapers to handle downtime. This is a lightweight simple to install but robust solution- all in one."
