SDE Forge
Freemium
Most engineers prepping for SDE interviews end up with five browser tabs, a Notion doc they stopped updating, and a LeetCode streak that doesn't tell them whether they can actually design a system. SDE Forge is built to close that gap — one dashboard for DSA tracking, system design practice, and AI feedback on your LLD and HLD submissions.

Summary
The dashboard consolidates company-specific DSA sheets (Grind 75, NeetCode, Striver and others), structured prep paths, and interactive lessons covering everything from cache invalidation to GoF design patterns. AI-assisted review on Low Level Design and High Level Design submissions is the sharpest differentiator — you submit a parking lot or Twitter design and get feedback on your architecture, not just whether the answer is right. Progress is tracked via heatmaps, per-topic stats, and streaks, so consistency is visible rather than assumed. AI feedback on design submissions is a paid-only feature, so candidates who hit that wall on the free tier either upgrade or return to forums for manual feedback. The tool has no API and no self-hosted option, meaning your prep data lives on their infrastructure, full stop.
Bottom line: Pick SDE Forge if you want DSA tracking, system design curriculum, and AI design-review in one place — but if your prep budget is zero and you need AI feedback on your HLD submissions, you will hit the paywall before you hit the offer.

Pros
- Company-specific DSA sheets aggregated from Grind 75, NeetCode, and Striver in one place, so you stop losing progress every time you switch between tabs or pick a new sheet mid-prep.
- AI-assisted feedback on LLD and HLD design submissions, which means you get architecture-level critique — not just 'correct or incorrect' — before facing an actual interviewer.
- Activity heatmaps and per-topic stats surface exactly where preparation has gone thin, so you are not walking into an interview having drilled arrays for three weeks while ignoring concurrency.
- Interactive curriculum covering distributed systems, GoF patterns, SOLID principles, and OOP fundamentals is vendor-stated as free, so the learning layer does not require a paid plan to access.
- Structured prep paths tied to target role and company give a clear milestone sequence, so a candidate starting from zero is not assembling their own curriculum from scratch.
Cons
- AI feedback on design submissions is a paid-only feature — candidates on the free tier get the DSA tracking and lessons but hit the paywall precisely when they need feedback on their parking lot or Twitter design, which is the exercise type that separates mid-level from senior-level interview outcomes.
- There is no shared or multi-user progress view, so engineers prepping in study groups cannot see each other's heatmaps or compare design submissions — groups doing collaborative prep revert to a shared Notion doc or a Discord channel running alongside.
- The platform has no API and no self-hosted option, meaning prep data cannot be exported to or synced with external tools — candidates who track progress in Obsidian or Notion end up maintaining two systems.
- Depth of AI design feedback is unverified against what a staff-level interviewer would give; if the feedback reads as surface-level after the first few submissions, candidates looking for senior-bar critique typically move to paid mock interviews with human engineers from platforms focused exclusively on live mock sessions.

Curated lists that include this category
Engineers juggling tabs and stale Notion docs often lose sight of whether their prep actually builds system design skills.
SDE Forge pulls company-specific DSA sheets from Grind 75, NeetCode, and Striver into one dashboard along with structured paths and lessons on topics such as cache invalidation and GoF design patterns. Submissions for Low Level Design and High Level Design receive AI feedback focused on architecture rather than simple right-or-wrong checks. Progress appears through heatmaps, per-topic stats, and streaks so weak areas become visible.
Core limits and paid features
The platform runs on a subscription model. Core tracking and lessons stay free, while AI review of design submissions requires a paid plan. No multi-user views or API access are provided.
Who it is for / who should skip it
Best for software engineers who want aggregated DSA sheets, interactive design lessons, and paid AI critique on LLD/HLD work before interviews. Skip it if you need free architecture feedback or shared progress views for group study.
