Go and Rust fit in the smallest plan
Under 50 MB of memory on average: a Go API runs comfortably with 256 MB reserved.
Numbers · October 2026
What runs on Syli Labs.
Every month, we publish what the sites we host really use: languages, memory, CPU, databases, builds. Anonymous averages, to help you choose and size your service.
In short
In October 2026, Node.js is still the most hosted language (31% of services). A Go service uses 41 MB of memory on average, compared with 588 MB for Java. PostgreSQL makes up more than half of all databases. 94% of builds succeed on the first try.

By language
How much does a service use, by language?
Average per service in Production, over 30 days. Static sites don’t count toward memory and CPU: they’re served from shared storage, with no server.
MB on average per service
Java and Ruby need the most memory; Go and Rust the least.
% of a core on average
Most sites use less than 10% of a core: they mostly wait for the database.
seconds, median
Static sites are ready in a few seconds; Rust takes a long time to compile.

Java and Ruby: plan for 1 GB
The average hides the peaks at startup. Below 1 GB, restarts caused by running out of memory increase.
Rust builds slowly, then costs almost nothing
More than three minutes to build, but the lowest CPU use once online.
Databases
PostgreSQL first, SQLite on the rise.

How the site is built
Why the others fail
- Dependency not found31%A library is missing from package.json or requirements.txt.
- Wrong listening port22%The application must listen on the PORT variable.
- Not enough memory17%The build uses more memory than planned, especially in Java and Rust.
- Missing variable14%An environment variable is read during the build.
Activity
Most releases happen at the end of the day.
Releases to Production by hour of the day (Conakry time, UTC). Peak at 6 pm.

Response time from Conakry: to be measured
Method
How we measure
- Measurements taken every minute on every service in Production, then averaged over the month.
- Development, Staging and feature environments excluded.
- Language and framework detected at build time. A group is only published if it has at least 20 services.
- No identifiable customer data: only totals and averages.
- CPU: average share of one core (vCPU) used.
