// Go backends
Go Backend Development Services
High-concurrency APIs, WebSocket services and microservices in Golang — built for the traffic spikes streaming apps actually get.
// What you get
Why teams choose us
Go backend development services are half of what Gravity Compile does. Our Go engineers build the services that sit underneath live streaming, real-time voice and in-app gaming: signaling, rooms, wallet ledgers, payments, moderation pipelines — the unglamorous, latency-critical code that keeps a product alive at 50,000 concurrent users.
We chose Go because it is honest about concurrency. Goroutines, channels and a standard library that does not hide the network make it straightforward to reason about a million WebSocket connections. Every backend we ship includes the boring essentials too: observability, graceful shutdowns, retries, circuit breakers and migrations that do not eat your weekend.
// Included
What's included
WebSocket & real-time services
Signaling, presence and pub/sub that handle tens of thousands of concurrent connections.
High concurrency API development
APIs designed against the 99th percentile, not the happy path.
Golang microservices
Small services with clear contracts, deployable independently and testable in isolation.
PostgreSQL & Redis the right way
Indexes, connection pooling and caching — the difference between 50ms and 5s.
Deployments & observability
Docker, CI/CD, metrics and alerting from day one, not after launch week.
TCP / WebRTC signalling
The signalling plane for rooms and voice agents — including our own Gravix Cloud nodes.
// Our stack
The stack
Full-stack, one team — designed in Figma, built in Flutter & Go, run in production. No hand-offs to strangers.
// How we work
Fixed timelines, visible progress
Discover
We audit your current services, traffic patterns and the pain points you actually hit.
Design
Service boundaries, data contracts and a migration path that avoids the big-bang rewrite.
Build
Two-week sprints with load tests included — performance is a feature, not an afterthought.
Run
Monitoring, incident response and the scale work that happens after launch.
// FAQ
Questions, answered
Go shines for network-heavy, latency-sensitive systems: real-time, streaming, IoT, payments. If your bottleneck is business-logic complexity rather than concurrency, we will tell you honestly and reach for the right tool.
Yes. We routinely rescue and modernize Go services built by other teams — audits, tests, then incremental improvement.
We deploy to AWS, DigitalOcean or your own cloud, and operate it if you want. Our SFU and real-time workloads run in production today.
It is our specialty. Signalling, token services and the SFU layer itself — see our WebRTC development services.
Every backend ships with a load-test harness aimed at your expected peak. We have seen 50K-concurrent launches; we plan for them.
