Transloadit API
Transloadit is a self-serve REST API for file processing: assemblies compose roughly 87 robots for transcoding and transformation, with tus resumable uploads and webhook notifications. Accounts start in a usable dev mode; GB-based billing with per-robot multipliers makes forecasting hard.

Transloadit scores A on the API Report Card. Transloadit is a self-serve REST API for file processing: assemblies compose roughly 87 robots for transcoding and transformation, with tus resumable uploads and webhook notifications. Accounts start in a usable dev mode; GB-based billing with per-robot multipliers makes forecasting hard.
Transloadit has a workable official integration path. Most engineering teams can build against it directly. Open API: self-serve, documented, with SDKs
Transloadit is a developer infrastructure company that provides a hosted API for uploading, transcoding, and delivering files, primarily images, video, audio, documents, and web content.
Vertical: misc, horizontal developer/media infrastructure. Transloadit does not fit any of Supergood's named verticals (Legal, Healthcare, Real Estate, Compliance, Financial Services, etc.). User-generated content uploads: accepting images, video, audio, documents from end-users via tus/Uppy on the client and an Assembly on the backend.
Mid-to-upper tier within developer media-processing APIs, but not the category leader.
End-user file uploads (images, video, audio, documents, archives) flowing through Transloadit on behalf of customer apps. Source storage credentials (AWS S3, GCS, Azure Blob, Cloudflare R2, Backblaze B2, Dropbox, Box, FTP/SFTP, 20+ providers) used for import/export Robots.
Founded 2009; one of the older players in the file-processing API category and pre-dates Cloudinary (2012) and most modern peers.
RATE_LIMIT_REACHED (HTTP 413) errors during burst loads; rate limits are per-account and trip on too-many simultaneous TCP connections or assemblies. Google Drive / OAuth-source uploads via Uppy's Transloadit plugin hit Google's per-project quota and return 'User Rate Limit Exceeded'. Full sourced list under Sources below.
Common alternatives include Cloudinary, Filestack, Uploadcare, ImageKit, Mux, Bytescale (formerly Upload.io). Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
