Developer Diagnostics for
Competitive Coders

Automate workspace environments, track coding diagnostics, and visualize performance trends without external database dependencies or usage tracking.

Productivity Workspace

Maximize Your Focus Zone

AetherCP runs quietly as a background runtime script, automating timing captures and loopback compiler configuration, keeping you in code flow.

Automated Timing Session Tracking

Initializes timing parameters automatically on loading problem page tabs. Operates silently without user triggers.

5-Minute Idle Detection

Pauses the timer after 5 minutes of inactivity. The session end time is retroactively corrected to when you actually stopped — not when the check fired.

VS Code Integration (CPH)

Sends the problem name, URL, all sample test cases, time limit, and memory limit to VS Code via the Competitive Companion protocol on localhost:27121.

Instrumented Codeforces Dashboards

Instrument your competitive workspace. AetherCP injects canvas visualizations directly into competitive dashboards, displaying submission records and mapping diagnostic trends.

Injected Profile Telemetry

Displays rating distributions, solved tag counts, and verdict breakdowns in real time directly on visited user profiles.

Solved Performance Timelines

Maps rating peaks to practice volume. Identifies preparation plateaus and tracks consistency trends.

Searchable Local Ledger

Keeps a structured history of timing durations, problem platform metrics, and metadata indexed for rapid lookup.

Category 03 • Visual Progress

Practice dashboards with Personality

Clean visual components that give your competitive programming habit a satisfying visual representation.

Today's Analytics

Popup shows total practice time, problems worked today, and most-worked problem. Updates every second from local storage.

Practice Heatmap

GitHub-style calendar grid tracking active days and duration intensity. Injected directly into your competitive homepage.

Streak Tracking

Counts consecutive days with any tracked practice time, using the IST timezone boundary. Shown on your own Codeforces profile.

Category 04 • Security & Offline

100% Local-First Architecture

Eliminate cloud databases. All practice statistics are sandboxed and persisted within your browser's client-side storage boundaries.

Privacy Shield

No sign-ups, no login tokens, and zero usage telemetry tracked backend.

Local Storage sandbox

Persistent logging utilizes local chrome.storage API inside sandbox.

No Third Party Access

Your coding logs, rating progress, and solved logs are never synced or uploaded.

Offline Execution

Runs natively in browser background. Offline usage caches locally until network access.
