SynapS3 lets Web2 object storage users use Filecoin Onchain Cloud like AWS S3. It provides an S3-compatible endpoint for Filecoin FOC, so existing S3 tools, applications, backup systems, data pipelines, and operators can use Filecoin storage without changing their storage interface.

Fully Open Source

SynapS3 makes Filecoin FOC usable through the S3 API. Most object storage users already understand AWS S3. They use S3 clients, SDKs, backup tools, data pipelines, media workflows, and S3-compatible applications. SynapS3 gives these users a direct path to Filecoin storage without requiring them to learn Filecoin-specific APIs, payment flows, or provider workflows. Users write objects through normal S3 APIs. SynapS3 persists the data locally, records metadata, and uploads it to Filecoin FOC in the background. Operators get a dashboard, wallet operations, task retries, health checks, metrics, and Docker deployment. The result is a practical bridge from existing Web2 object storage workflows to paid Filecoin storage.

S3 is the default interface for many object storage users. Filecoin FOC needs simple paths for those users to try, adopt, and operate Filecoin-backed storage. SynapS3 turns Filecoin FOC into an S3-compatible endpoint. This lowers adoption cost for existing applications and operators because they can keep their current storage interface while SynapS3 handles the Filecoin side. Each successful S3-to-FOC workflow creates a practical path toward paid Filecoin storage usage.

S3 Compatibility & End-to-End Validation SynapS3 will validate core S3 workflows using AWS CLI, rclone, and MinIO Client against a documented compatibility matrix. Validation will cover core bucket and object operations, multipart uploads, versioning, copy/delete flows, and the complete S3 → cache → Filecoin FOC data path. Reliability & Product Validation SynapS3 will be tested with representative real-world S3 workloads and deployment environments. Validation will cover data integrity, retry and recovery behavior, interrupted operations, and common Filecoin/provider failure scenarios. Issues identified through testing and early real-world use will be addressed or documented as known limitations. Public Release & Reproducibility SynapS3 will publish versioned releases, Docker images, compatibility documentation, and deployment/operational guidance. Users should be able to deploy SynapS3, connect supported S3 clients, use the documented core workflows, and inspect operational or upload failures using the provided tooling.

SynapS3 is an independent project led by Lee. Lee brings over 10 years of software development experience, including 7 years in the IPFS/Filecoin community and more than 5 years working at storage provider companies. The work covers implementation, Filecoin FOC integration, testing, documentation, releases, and community support.

Core delivery risk is low. The main gateway, S3 compatibility layer, FOC upload pipeline, dashboard, Docker deployment, and documentation are already implemented. Remaining risks are limited to external dependencies such as FOC/Synapse SDK changes, provider behavior, and network availability during validation.

The main SynapS3 workflow is already implemented and ready for deployment and testing. Documentation is available here: https://synaps3.strahe.com/en/
