Three categories. One file infrastructure.
Every app on this page solves a different problem — but they all run on the same Filestack primitives.

Students submit assignments from any device. Auto-OCR, plagiarism checks, and instructor dashboards — all built on uploads.
View use case →One SDK call replaces a month of plumbing
Every use case on this page started with the same six lines of code. The picker handles uploads from local disk, Drive, Dropbox, Instagram, and URL — encrypted, virus-scanned, and chunked over flaky connections.
- 20+ source integrations out of the box
- Automatic image transforms & CDN delivery
- Virus scan, OCR, and SFW detection on demand
- Resumable uploads up to 5 TB per file
client.picker({
maxFiles: 10,
fromSources: ['local_file_system', 'gdrive'],
onUploadDone: res => save(res.filesUploaded)
}).open();
// Done. Your users can now upload anything.

Common questions
Are these apps open source?
Yes. Each use case page links to a public GitHub repo with a permissive license. Fork it, swap your API key, and deploy.
Can I use Filestack for free while I build?
Yes — the free tier includes 250 uploads, 1 GB of storage, and 1 GB of monthly bandwidth, with no credit card required. Plenty for prototypes and side projects.
Which frameworks do the samples use?
You’ll find a mix of React, Next.js, Vue, and vanilla JS. The Filestack SDK works the same in all of them — pick the sample whose stack matches yours.
Can Filestack handle student records or signed legal forms?
Yes. Filestack offers SOC 2 Type II compliance, encryption at rest and in transit, and signed-policy uploads so only authenticated users can write to your storage.
What if my use case isn't on this page?
