Go is a compiled language from Google designed for network services. It produces a single executable file with no runtime dependencies, starts in milliseconds and uses very little memory. We use it for focused, high-traffic services rather than for whole applications.
What is Go?
Go was designed at Google for a specific job: services that handle a lot of concurrent network traffic, written by large teams, deployed constantly. Every design decision follows from that.
It compiles to one self-contained binary. There is no runtime to install on the server, no dependency tree to resolve at deploy, no version of an interpreter to keep in sync — you copy one file and run it. For operations, that is a materially simpler thing to own than any interpreted language.
The language itself is deliberately small. There is usually one obvious way to do something and few clever ones, which makes Go code from an unfamiliar team unusually easy to read. That is boring in the best sense: it is the property you want in the component that must not surprise you at 3am.
When we choose Go
For one component under unusual load inside a larger system. A webhook receiver taking thousands of requests a minute, a token service every other service calls, an image resizer. Go handles those on hardware that would struggle in an interpreted language.
When operational simplicity is the priority. A single binary with no dependencies is the easiest thing to deploy, roll back and reason about, and on a system with a small ops team that is worth more than developer convenience.
When we do not use Go
For a whole business application. Go's deliberate minimalism means writing a lot of code that Laravel or Django would have given you, and for a CRUD-shaped system that is a poor trade.
For content management. There is no Go CMS a marketing team should be asked to use.
And for a client with no Go developers, unless we are also providing the support contract — a single binary is easy to run and a Go codebase is not something a PHP team will pick up over a weekend.
What we build with Go
High-volume ingest endpoints
Webhook receivers and event collectors taking sustained traffic that would need several times the hardware in an interpreted language. Usually one small service alongside a Laravel or Node application rather than replacing it.
Internal tools and CLIs
Deployment helpers, data migration tools, monitoring agents. Compiling to one file for any operating system means a tool that works on every machine in the team without anyone installing a runtime first.
Services that handle sustained load
Ingesting telemetry, processing queues, handling thousands of concurrent connections. Go does this on modest hardware, which turns a scaling problem into a hosting line item that does not grow.
Command-line tools and workers
Go compiles to a single file with no runtime to install, which makes deploying a scheduled job or an internal tool a matter of copying one binary onto a server.
How we ship Go projects
Small and single-purpose. Go is at its best as one service doing one job inside a system built mostly in something else, and at its worst as an attempt to write an entire application in it.
Handed over with the source and a build script, since the binary is opaque. A client holding only a compiled file has not really been given the code.
What Go costs you
You write more code for the same feature. Go has no framework that hands you authentication, an admin panel and an ORM, so anything conventional costs more than it would elsewhere.
The hiring pool in the GCC is small. If the client needs to maintain it without us, that is the constraint that usually decides against it, and we say so.
The language is deliberately small, which means more code for things other languages express in one line. Developers coming from PHP or JavaScript find it verbose at first, and most stop minding within a fortnight.
The ecosystem is also thinner for web application work specifically — there is no Laravel equivalent, so more is assembled by hand. That is fine for a focused service and a poor trade for a content site.
Go questions we get asked
Almost certainly not. Go earns its place as one focused service inside a system built mostly in something more productive for ordinary features. Writing an entire business application in it means rebuilding a lot of what Laravel or Django would have given you.
When the work is CPU-bound or the connection count is genuinely high. Node stalls on heavy computation because one operation blocks the process; Go handles it in parallel across cores. For ordinary API work that waits on a database, Node is fine and faster to build.
Harder than PHP or JavaScript, yes. That is a genuine reason not to build your whole system in it. Using Go for the one service that needs it, with the rest in something easier to staff, gets the performance without the hiring problem.
It could, and it usually should not. Rewriting a working backend for performance you have not measured is the most expensive way to solve a problem you may not have. We would rather find the actual bottleneck and move only that.
Less than the equivalent in most other languages, which is often the point. A Go service handling the same load typically needs a fraction of the memory a Node or Python one does, so the saving shows up every month on the hosting bill rather than once in the build.
Only if the team maintaining it writes Go. For most clients the better shape is one Go service handling the part that genuinely needs it, with the website and admin in something easier to staff locally. That gets the performance where it matters without making every future hire harder than it needs to be.
