Codenames: from Manhattan Project to product launches

A codename is a secret alias for a project, person or operation. The practice is ancient in warfare and modern in tech. The atomic bomb program was the Manhattan Project; the Allied invasion of Normandy was Operation Overlord; Operation Mincemeat was the WWII deception that floated a fake British corpse with planted documents to mislead the Axis.

Tech companies use codenames to ship features without leaking branding or strategy. Apple names macOS releases after California landmarks (Cheetah, Tiger, Mavericks, Big Sur, Sonoma, Sequoia); Google's Android used desserts in alphabetical order until 2019 (Cupcake, Donut, Eclair, ..., KitKat, Lollipop, Marshmallow, Nougat, Oreo, Pie, Q); Microsoft Windows shipped under names like Chicago (Windows 95), Whistler (XP) and Longhorn (Vista); Mozilla's browser was Phoenix, then Firebird, then Firefox due to trademark conflicts.

Why use a codename

• Secrecy — legitimate confidentiality or NDA cover
• Brevity — easier in conversation than "Project 2026-Q3-Pricing-Refactor"
• Pre-launch branding — internal identity before the public name is set
• Verbal clarity — distinct names reduce confusion across teams

Types of codename patterns

Random word lists give punchy single-word names (Skull, Ghost, Falcon, Mirage). Thematic sets bind a family of releases — NASA's Mars rovers are named for traits (Curiosity, Perseverance). Alphabetical sequential sets like Apple's big cats or Android's desserts make ordering obvious. The NSA's surveillance codenames disclosed by Edward Snowden in 2013 — PRISM, Tempora, XKeyscore — show the genre at full bureaucratic scale.

Best practices and failure modes

A good codename is short, distinct, harmless (avoid offensive or politically charged terms), not previously associated with another product, and ideally has an available domain or repo name. Common failures: leaks (the Manhattan Project's name became public during the war), unfortunate associations (FBI's Carnivore was renamed DCS-1000 after public backlash), or accidental trademark collisions (Mozilla's Firebird clashed with an existing database project). In Brazil, Operação Lava-Jato (Carwash) became a memorable, broadcast-friendly codename for a major anti-corruption probe.

FAQ

Can I use a generated codename as my final product name? Be careful — always run a trademark check (USPTO / INPI for Brazil), domain check and basic web search before committing. A great codename is not necessarily a clean brand.

Random or thematic codenames — which is better? Thematic series are more memorable across releases (you remember Big Sur belongs to a set), but random codenames are faster to pick for one-off projects. Choose by need.

Is a codename useful for small companies? Yes. It lets teams discuss in-flight work without prematurely committing to a brand, and gives marketing room to choose the public name later without confusing internal docs.

What should I avoid? Real military operation names, names of currently shipping products from other companies, anything politically loaded or offensive in any of the languages your team speaks. Bland and forgettable beats catchy and litigious.
