Learning and careers decision
EnglishWithLewis
A single capable developer can build and self-host a functional replacement using existing open-source projects; the vendor's likely polish and any proprietary lesson content would be the main losses.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All EnglishWithLewis alternatives, with the arithmetic →
What a replacement has to do
- Host short authentic audio/video lessons, let a learner listen/record speaking, compare or transcribe responses, schedule spaced repetitions, and track progress in a user profile.
What it still won’t have
- polished UX, onboarding flows, and marketing polish
- proprietary curated lesson catalog and any licensed media
- managed hosting, analytics dashboards, and live customer support
- mobile-native apps and app-store distribution (unless built separately)
What remains hard
- Product polish and ongoing maintenance

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a self-hosted web app (Node.js + Express backend, Postgres DB, React frontend) that serves short audio/video English lessons with transcripts, lets users record audio in-browser and upload to S3-compatible storage, sends uploads to a configurable speech-to-text/pronunciation API, stores transcripts and pronunciation scores, implements a spaced-repetition scheduler for lesson review, and provides user auth and progress pages. Out of scope: mobile native apps, paid billing, and third-party content licensing. Include error handling, input validation, CI tests for backend endpoints, and deployment scripts for a single DigitalOcean or AWS instance.
How we checked
How the score was reached
- Build verdict base78
- An open-source build was found+5
- 3 cited sources+3
- Evidence score86
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
