100daysof.codes

What It Is

100daysof.codes is a browser new-tab extension provided by GIGAHERTZ INNOVATIONS LLP. Its positioning is very focused: helping learners participating in #100DaysOfCode set daily goals, maintain a coding habit, and track their learning streaks. It is not a traditional IDE plugin or code-hosting tool, but is closer to a “developer learning habit management + focus tool.”

Core Features

Based on the main content, the product includes three key capabilities: Learning mode, Task planner, and Streak calendar. Learning mode provides a Pomodoro timer and supports blocking distracting websites, making it useful for reducing procrastination while studying. Task planner is used to plan and schedule tasks for the coming days, helping users clarify what to do next. Streak calendar lets users view their check-in streaks and consistency level. Since it appears as a new-tab extension, its entry point is relatively natural and well suited to self-learners who frequently open their browser.

Languages, Openness, and Integrations

The main text does not specify which programming languages or frameworks are supported, nor does it mention integrations with GitHub, calendars, to-do tools, learning platforms, or other external services. API/SDK and self-hosting options are also not disclosed. There is no clear statement about open source either; the terms instead emphasize that the intellectual property rights for website materials are owned by the company or its licensors, with all rights reserved. Therefore, it should be understood as closed-source or with source code not publicly available.

Pricing and Documentation

The page terms mention that the website and information services are provided free of charge without liability for losses. Combined with the fact that the main content does not mention subscriptions or paid plans, the currently available public information suggests a free model. However, it is unclear whether there are premium features, account sync limitations, or future paid plans. Documentation quality is average: the marketing page explains the features quickly, but lacks details on browser compatibility, installation steps, privacy and data handling, troubleshooting, and functional limitations.

Pros, Cons, and Best-Fit Users

Its strengths are a focused use case and low barrier to entry, combining goals, planning, a Pomodoro timer, and streak tracking in one place. It is suitable for beginners building a coding habit, self-taught frontend learners, and #100DaysOfCode participants. Its weaknesses are limited feature depth and insufficient ecosystem information, making it unsuitable for users who need team management, learning analytics, code platform integrations, or a self-hosted solution.

Access from China

The main content does not provide information about access, payment, or mirrors for mainland China, so actual availability is unknown. If access is unstable, alternatives include Notion check-in templates, Todoist, Habitica, Forest, or 100DaysOfCode tracking methods from the GitHub community.
