Flags in code let you ship features switched off, roll out gradually, and mark lines that need attention. Guides to flags done well — and cleaned up after.

What Code Flag Does
A flag in code is a marker — a feature flag that switches behavior on and off, or a flag raised on a line that needs attention. CodeFlag.com covers both readings of the words.
Ship code dark, switch it on for one user, ten percent, then everyone.
Percentage rollouts, allowlists, and kill switches — when to use which.
Every flag is a debt with a due date: how to find and delete stale ones.
TODO, FIXME, and review flags — conventions that make markers actionable instead of noise.
How to test both sides of every switch without doubling your suite.
Names that say what turns on, for whom, and when it can die.
How Code Flag Works
Wrap the new behavior in a named switch, shipped off by default.
Flip it on for a slice of users and watch what changes.
Once the rollout is decided, delete the flag and leave one code path.
About
CodeFlag — Flags in code: switch it or flag it. Part of the VentureOS network of 20,000+ smart entities, each built to create real value in its vertical. Backed by 63+ specialist agents, shared infrastructure, and a unified economy.
An if-statement controlled from outside the code: the feature ships switched off, and you flip it on for chosen users without redeploying.
When they outlive their rollout. A flag past its decision date is dead branching logic — schedule its deletion the day you create it.
They are the older kind: a marker planted in code that says look here. They work only if your team has a convention for sweeping them.

Not a website. Not a landing page. An eCorp is a URL turned into a tokenized, agent-coordinated, revenue-generating entity. Here's the unpacked definition.
