Idle Dev Startup is a browser-based idle simulation game that centers on building and managing a growing software development business through automated progression. The player controls a small startup environment where coding actions generate revenue that increases over time. By actively clicking or relying on idle production, the player earns income and reinvests it into upgrades that improve development speed, efficiency, and automation. Each upgrade pushes the startup into higher production tiers, increasing both rewards and costs. The difficulty scales gradually as progress slows at later stages, requiring smarter investment decisions instead of constant interaction. Engagement comes from balancing manual input with idle systems while watching numbers steadily rise. The game focuses on long-term growth rather than short bursts of action, allowing progress to continue within a single session. The experience closely aligns with other idle games such as Cookie Clicker but applies the loop to a development-themed setting.
The objective is to expand the startup by generating income, purchasing upgrades, and automating development tasks until growth reaches advanced production stages. Progress depends on sustaining revenue flow and unlocking systems that reduce manual effort.
The game features a single continuous mode with no separate levels. Progression unfolds through development stages as upgrades unlock new efficiencies, higher income rates, and deeper automation.

Spacebar = Manual coding / Generate income (Alternate)
Esc = Open Settings / Pause Menu
Mobile Controls:
Single Tap = Interact with menus / Buy upgrades / Select workers or tasks
Tap and Hold Screen = Accelerate manual coding/production
Swipe Left / Right = Navigate between different office floors or departments
Tap "Upgrade" Icon = Level up developers, equipment, or technologies
Tap "Manager" Icon = Hire managers to automate manual tasks
Tap Pause Icon = Open Settings / Pause Game
The session starts with a basic development setup already active on the screen. The player clicks or taps to manually generate income through coding actions while passive income accumulates in the background. Earnings allow the player to purchase upgrades that increase output speed and automate repeated tasks. The player regularly checks income flow, unlocks managers, and improves tools to reduce the need for constant interaction. Progress slows if upgrades become too expensive, which pushes the player to rely more on idle generation. Failure does not end the session but appears as stalled growth that requires manual input to recover. As upgrades stack, production becomes increasingly automated, allowing progress to continue with minimal interaction until the session naturally plateaus.
