Instrument events in code
Capture calls go through a typed helper with shared property names, so web, backend and mobile report the same event the same way.
4.9 / 5PostHog developers for code your product team can trust.
PostHog developers who write the tracking, feature flag and experiment code inside your app, across web, backend and mobile.

PostHog installs in minutes. The code that makes its events and flags dependable takes real engineering.

What's included
Written into your codebase.
We work in your repository, through your review process, and leave code your engineers are happy to maintain.
Wire in feature flags
Flags evaluated server-side or bootstrapped into the first render, so gated features appear without flicker and roll out by cohort or percentage.
Build experiment variants
Each variant sits behind a multivariate flag, with the goal metric set in PostHog and exposure logged before any result counts.
Validate before release
Every event and flag is checked in a preview environment against the tracking plan, then again in production after the release.
Security, by consideration.
Trust is part of the build.
For your PostHog project, we consider event collection, personal data, workspace access and ingestion endpoints as part of one connected build.
See our approachConnected systems. Considered safeguards.
Changes you can trace.
GitHub workflows, peer review and dependency checks bring decisions into the release process.
Protected in transit.
Certificate configuration, HTTPS and secure headers help protect the path between your users and your systems.
Intelligence with limits.
Scoped tool access, validated inputs and human approval where automated actions carry consequences.
From plan to pull request.
You see every change as a pull request before it merges.
- 01
Read the codebase
We review your stack, existing PostHog calls and release process, then agree what to instrument first.

Build and review
Events, flags and variants go in as small pull requests your team reviews and merges.
- Pull requests
- Flag definitions
- Test notes

“Stega Creative team not only understood our needs and vision for the websites, but they also came up with improvements.”
PostHog development questions.
A few things worth discussing before your PostHog development takes shape.
Do I need a developer to set up PostHog feature flags?
You need a developer to wire PostHog feature flags into your code, though not to create them. Flags are defined in the PostHog dashboard, but your app has to read them. Server-side evaluation and bootstrapping also take engineering work if pages must render without flicker.
How do you stop PostHog feature flags causing page flicker?
PostHog feature flags stop flickering when the flag value is known before the page renders. We evaluate flags on the server with local evaluation, or bootstrap the values into the client on first load. Visitors see the right variant straight away instead of a swap after the script loads.
Can PostHog track events from our backend as well as the website?
PostHog tracks backend events through server SDKs for Node, Python, Ruby, Go, PHP and more. We send events such as subscription started or invoice paid from the server, where ad blockers cannot drop them, and tie them to the same person as their browser events.
How much does PostHog development cost?
The price depends on how many platforms need instrumenting, how many flags and experiments are in scope and whether your codebase already has a tracking layer. You get a fixed scope after a short code review.
