# Undeprecated

> Undeprecated keeps software engineers' coding skills sharp in the age of AI assistants. Engineers do short (10-minute) practice sessions, about three times a week, writing and reading real code without AI help. Companies buy team plans so managers can see their engineers are keeping their skills current.

## Who it is for

- Individual software engineers who use AI coding assistants daily and want to keep the ability to write, read, debug and review code themselves (also useful for interview readiness).
- Engineering managers and team leads at companies that want measurable, low-effort skill retention for their teams, especially enterprise stacks such as Java/Spring Boot, Salesforce Apex/LWC, .NET, and cloud infrastructure.

## How it works

- 10-minute sessions by default (5 to 20 minutes configurable), recommended three times per week.
- Exercise formats: write a method from scratch, predict a program's output, spot the bug, reorder shuffled lines, fill in the blank, and pick the correct syntax.
- Spaced repetition brings missed material back right before it would be forgotten; every skill has its own rating so difficulty adapts.
- Content covers three eras: core fundamentals, modern syntax tagged with the version that introduced it (for example Java 21, Spring Boot 3, Python 3.12, ES2023, C# 12, Apex API 60), and legacy patterns still common in production code.

## Grading and integrity

- Every answer is graded on Undeprecated's servers; answer keys never reach the browser.
- Real code answers are compiled and run in a sandbox against hidden test cases.
- AI reviews written code against an expert rubric and gives specific feedback; deterministic rules (for example, no SOQL inside loops in Apex) override the AI.
- Paste is blocked and there is no autocomplete. Tab switching and implausibly fast answers are recorded and flagged on scores and team reports.

## Languages and frameworks (launch tracks)

Java, Spring Boot, Play Framework, Quarkus, Hibernate/JPA, Kafka, Kotlin, Scala and Apache Spark, Salesforce Apex, Lightning Web Components (LWC), SOQL, JavaScript, TypeScript, Node.js, React, Next.js, Angular, Vue, Python, Django, FastAPI, C#, ASP.NET Core / .NET, Go, Rust, C++, Swift, PHP and Laravel, Ruby on Rails, SQL, Oracle PL/SQL, SQL Server T-SQL, SAP ABAP, COBOL, GraphQL, Terraform, Kubernetes, Docker, Ansible, Bash, PowerShell. Teams can request additional stacks.

## For teams and managers

- Completion alerts when the whole team hits its weekly goal, and a heads-up before the week closes listing anyone behind.
- Weekly digest by email, Slack or Microsoft Teams; skill heatmap across the team's stack.
- Integrity flags so scores can be trusted; privacy controls let admins show individual scores or team totals only.

## Pricing

- Individual: $9 per month or $79 per year.
- Team: $12 per seat per month, 5-seat minimum.
- Enterprise: custom pricing with SSO, custom tracks for internal frameworks, and Slack/Teams integration.

## Privacy

Undeprecated is operated by Tech Shepherd LLC. No ads and no selling of personal data. Submitted Apex code is sent to a DeepSeek model on Microsoft Azure AI Foundry for rubric grading; other code runs in an isolated sandbox on Cloudflare. Data deletion on request: privacy@undeprecated.dev.
