v1.27.07 July 2026

The new courses go deeper

We're expanding our newest courses with more lessons, more practice, and advanced topics — plus brand-new interactive diagrams built specifically for each one, so React, Vue, and the rest each get visuals made just for them. Rolling out course by course.

  • React, expanded — The React course now goes from your first useState all the way to custom hooks — immutable updates, lifting state, useEffect cleanup, useRef/useContext, controlled forms, and performance, with four React-only interactive diagrams.
  • Vue, expanded — The Vue course now covers the full reactivity system (ref, reactive, computed, watch), slots, provide/inject, lifecycle, and composables — with four Vue-only interactive diagrams instead of shared ones.
  • FastAPI, expanded — The FastAPI course now goes deep — dependency injection, middleware and CORS, background tasks, async, databases, and testing — with three FastAPI-only interactive diagrams.
  • PostgreSQL, expanded — The Postgres course now covers transactions and ACID, constraints, normalization, and performance — with interactive diagrams for index scans, transactions, and reading a query plan with EXPLAIN.
  • Django, expanded — The Django course now covers class-based views, template inheritance, ORM relationships and the N+1 problem, forms, auth, middleware, and REST Framework — with three Django-only interactive diagrams (MVT flow, ORM→SQL, migrations).
  • System Design, expanded — The System Design course now digs into caching strategies, replication and sharding, CAP and consistency models, rate limiting, CDNs, and SLAs — with interactive diagrams for cache-aside, sharding, and the CAP trade-off.
  • MongoDB, expanded — The MongoDB course now covers query operators, schema-design patterns, compound indexes, the aggregation pipeline, and replica sets/sharding — with interactive diagrams for the document model, embed vs reference, and the pipeline.
  • Redis, expanded — The Redis course now covers all five data types, atomic operations and transactions, pub/sub and Streams, persistence, and eviction — with interactive diagrams for the data types, TTL expiry, and pub/sub.
  • Celery, expanded — The Celery course now goes deep — result backends, retries and idempotency, acks_late, worker concurrency and queues, Canvas workflows (chains, groups, chords), scheduling, and monitoring — with three Celery-only diagrams for the task flow, retries with backoff, and scaling workers.
  • Claude Code, expanded — The Claude Code course now covers the agent loop, its tools, permission modes, plan mode, rewind, slash commands, subagents, hooks, and MCP — with three Claude Code-only interactive diagrams for the agent loop, the tool palette, and permissions.
  • Low Level Design, expanded — The Low Level Design course now covers all five SOLID principles, composition over inheritance, and a full set of creational, structural, and behavioral design patterns — plus a parking-lot worked example — with three new interactive diagrams for classes vs objects, encapsulation, and the Strategy pattern.
  • Microservices, expanded — The Microservices course now covers service boundaries, discovery, the saga pattern, resilience (timeouts, retries, circuit breakers, idempotency), and operations (containers, tracing, independent deploys) — with three microservices-only diagrams for the API gateway, sync vs async messaging, and a saga converging across services.
  • Micro Front-ends, expanded — The Micro Front-ends course now covers the app-shell model, cross-app communication, performance and delivery (shared dependencies, lazy loading, independent deploys), and reliability (fault isolation, contracts, team ownership) — with three new interactive diagrams for team-owned composition, build-time vs run-time, and Module Federation.
  • Web Servers, expanded — The Web Servers course now covers config structure, compression, security (HTTP→HTTPS redirects and hardening), operations (timeouts, zero-downtime reloads), and troubleshooting 502/504 errors — with three web-server-only diagrams for request routing, load balancing with failover, and TLS termination.
  • Every new course, deeper — with its own diagrams — All fourteen of the newest courses now go further (around 18–23 lessons each) and each ships interactive diagrams built specifically for it — over 40 new visuals in total, so no two courses reuse the same generic diagram anymore.
v1.26.07 July 2026

A wave of new courses

We're expanding the catalog with hands-on courses on today's most-used backend, frontend, and architecture tools — each beginner-first, packed with quizzes and playable diagrams, and slotted into the right learning path. Starting with FastAPI, with more rolling out.

  • FastAPI — Build modern, typed Python APIs — path and query parameters, Pydantic request bodies, clean status codes and errors, and a first taste of async.
  • PostgreSQL — Store and query real data with SQL — tables and the relational model, SELECT and filtering, safe writes with transactions, keys and JOINs, plus indexes and JSONB.
  • Redis — Make apps fast with in-memory data — caching, auto-expiring keys, counters and leaderboards, and pub/sub messaging.
  • Celery — Run slow work in the background — define tasks, queue them with .delay(), and add retries and scheduled jobs so your app stays snappy.
  • MongoDB — Store flexible JSON-like documents — collections and CRUD, query filters, embedding vs referencing, and indexes.
  • Claude Code — Pair-program with an AI agent in your terminal — give it context, review its changes, and keep control. Plus a new AI-Assisted Developer path.
  • System Design — Design systems that scale — requirements and estimation, load balancers, caches and queues, replication and sharding, and reliability trade-offs. Starts a new Software Architecture path.
  • Low Level Design — Write clean, flexible code with object-oriented design — the four OOP pillars, SOLID principles, and essential patterns like Strategy and Factory.
  • Microservices — Split a big app into small, independent services — how they communicate over APIs and queues, the role of an API gateway, and the data trade-offs to weigh.
  • React — Build interactive UIs from reusable components — JSX, props and state, lists, events, and effects, plus the 'thinking in components' mental model.
  • Vue.js — The approachable frontend framework — components and templates, reactivity, directives like v-model and v-for, props and events, and the Nuxt ecosystem.
  • Micro Front-ends — Microservices for the browser — split a big frontend across teams, compose pieces at build or run time, and handle shared state, styling, and routing.
  • Django — Build full web apps fast with Python's batteries-included framework — the request flow, URLs, views and templates, the ORM and migrations, and the free admin.
  • Web Servers (NGINX & Apache) — Understand the software in front of every website — serving static files, reverse proxying to your app, load balancing, caching, and handling HTTPS.
v1.25.07 July 2026

Beat the final exam, earn your certificate

Finish a course and a new game-based final exam unlocks — answer questions one at a time, build a streak for bonus points, and score 70% or more to pass. Passing is now how you earn your certificate.

  • A final exam that plays like a game — Ten questions drawn from the whole course, a live score and streak counter, and a results screen that tells you exactly how you did.
  • Certificates you truly earn — Pass the exam to unlock your certificate. Didn't pass? Retake it any time — the questions reshuffle for a fresh challenge.
v1.24.07 July 2026

Start any course over

Want a fresh run at a course? You can now restart it from the course page — your progress for that course resets so you can take it again, and your other courses stay exactly as they are.

  • Restart a course — A new Restart button on each course clears just that course's progress for a clean retake. Your streak and other courses are untouched.
v1.23.07 July 2026

Finished a course? Here's what's next

When you complete a course, we now suggest the perfect next step — the next course in your path, or another great fit — so you never have to wonder where to go from here.

  • A clear next step — Finish a course and a 'what's next' card appears with a recommended course and a one-tap way to jump straight in.
v1.22.06 July 2026

Learning that adapts to you

With your permission, Learners.Center now pays attention to how you learn — the time you spend, how you answer quizzes, and where you get stuck — the groundwork for tailoring your path and recommendations to you. You're always in control: manage it any time in Settings → Privacy.

  • Insights that personalize your learning — We've begun learning how you learn — your reading time, quiz answers, and where you leave off — so we can shape a path that fits you. It records your interactions, never the text you type, and stays private to your account.
  • You're in control — New privacy controls in Settings let you turn learning insights on or off, and opt in to community matching. Turn insights off and we stop collecting and clear anything not yet synced.
v1.21.04 July 2026

Diagrams you can play with

Our concept diagrams are becoming mini-games: resolve a real merge conflict, keep a repo in sync with GitHub, pick the right undo — learn by doing, right inside the lesson. Starting with the Git course and rolling out across every course.

  • Learn by playing — New interactive diagrams give you a goal, let you click and choose your way through, and cheer you on when you nail it — no more just reading.
  • Git, hands-on — Resolve a merge conflict line by line, sync your local repo with GitHub, undo mistakes safely, and predict exactly what .gitignore will hide.
v1.20.04 July 2026

A cleaner, more consistent look

We refreshed the interface around one clean, consistent icon style — across courses, paths, the dashboard, notifications and reminders — so everything feels calmer and more cohesive. Color now comes from our signature pastel blocks, not scattered emoji.

  • One consistent icon set — Course and path badges, notifications, reminders, menus and chips now share a single, tidy line-icon style instead of a mix of emoji.
  • Easier to scan — Cleaner course cards, syllabus and dashboard make it quicker to find your place — the pastel colour-blocks do the pop, the icons stay calm.
v1.19.04 July 2026

Learning reminders that pick up where you left off

Learners.Center now nudges you back to the right place: resume your in-progress course in one tap, or get a recommendation to start when you haven't picked one yet — in the app, and (if you allow) as browser notifications.

  • Resume in one tap — A nudge on your dashboard links straight to the exact lesson you left off on — no hunting for your place.
  • Not sure what to learn next? — When you haven't started a course, we suggest a great one to pick — so you're never stuck at a blank page.
  • Opt-in reminders — Turn on Learning reminders in Settings for gentle nudges to keep your streak going — in the app, and as browser notifications if you allow them.
v1.18.04 July 2026

Notifications — and a Follow button that works

A new notification centre keeps you in the loop: see who followed you, jump to trending courses, and celebrate finishing a course — each with a link that takes you straight there. And the Follow button on public profiles now works reliably.

  • Your notification centre — A bell in the top bar shows your unread count, and a full Notifications page lists everything. Every notification links straight to the action — a learner's profile, a course, or your certificate.
  • Know who followed you — When another learner follows you, you'll get a notification with a link to their profile — so you can follow them back.
  • Trending picks — A weekly nudge points you to a course learners are loving right now.
  • Follow button fixed — Following someone from their public profile now works reliably — and clearly tells you if something goes wrong.
v1.17.01 July 2026

The AI tutor can now reply in your language and draw the same interactive diagrams you see in lessons.

  • Ask in your language — Pick a reply language from the tutor's header — Auto (it matches you), English, Hindi, Bengali, Tamil, Telugu, Marathi, and more. The tutor answers in that language while keeping code exactly as it should be.
  • Diagrams in chat — When a picture helps, the tutor now drops in one of the module's interactive diagrams right in the conversation — the same animated visuals you see in the lessons.
  • Side-by-side, not on top — On desktop and tablet the tutor now gently shifts the lesson aside instead of covering it, so you can read and chat at the same time.
v1.11.030 June 2026

Meet your AI tutor

Every module now has a built-in AI tutor — tap "Ask AI" on any lesson to get instant, on-topic help.

  • Ask AI, per module — A new "Ask AI" button on lessons opens a chat that knows the module you're studying. It stays on topic, explains things simply, and answers with the same clean cards and code blocks you see in lessons.
  • Focused and fresh each module — The tutor is grounded only in your current module, so its help is relevant. The conversation resets when you move to a new module, and nothing is saved.
  • Tucks in on the side — On desktop it slides in as a side panel so you can keep reading; on your phone it opens full-screen. Suggested follow-up questions keep the conversation flowing.
v1.10.030 June 2026
