Self-hosted application platform and object storage

Workers-compatible apps and S3 storage, on your own servers

TotisWorkers runs apps written against a subset of the Cloudflare Workers API, with SQL, KV, queues and jobs built in. TinyS3 is erasure-coded, S3-compatible object storage. Both run on hardware you control.

Every service, briefly: TotisWorkers services · TinyS3 services

The problem

Self-hosting an application stack means running a web runtime, a SQL database, a key-value store, a queue, a scheduler, mail delivery and object storage as separate systems: seven deployments, seven backup procedures, seven upgrade paths.

TotisWorkers and TinyS3 replace them with one platform and one storage layer.

Proof points

S3 conformance comes first; the ERP numbers are a single-node dev test, not a production benchmark.
