S3-compatible storage proxy

Smaller object storage.
Unchanged S3 workflows.

DeltaGlider Proxy stores repeated binaries as compact deltas behind an S3-compatible API. Your applications keep using the same S3 clients; operators get the controls needed for production.

Business impact

Reduce cost, keep control, avoid rewrites.

DeltaGlider is designed for teams with growing S3-compatible storage and existing clients they do not want to change.
Lower storage growth

Store repeated binaries as compact deltas while clients continue to use normal S3.

Control access

Manage users, groups, OAuth, ABAC permissions, public prefixes, and audit visibility from your own environment.

Run it simply

Configure backends, buckets, quotas, replication, TLS, caches, limits, and logs from one admin UI.

Operations

Everything operators need in one place.

Monitor usage, manage identity, configure bucket policy, set soft quotas, and run replication from the embedded admin UI.

Product view

Dashboard view for request health, cache behavior, memory, errors, and object totals.

Observability

Monitor storage and runtime health.

Track requests, latency, cache behavior, object counts, memory, and error rate from the embedded dashboard. Use Prometheus metrics when you need long-term monitoring.

  • Request rate and latency
  • Cache and memory visibility
  • Prometheus-ready metrics

DeltaGlider Proxy object replication settings page
Product view

Rule-based object replication with scheduler controls, history, failures, and delete replication.

Replication

Replicate through the proxy.

Copy objects between buckets or backends without bypassing the DeltaGlider engine. Rules can run on a schedule, run on demand, pause, resume, and replicate deletes.

  • Source to destination rules
  • Run history and failures
  • Optional delete replication
live product
DeltaGlider Proxy IAM users page
Product view

IAM surface for S3 credentials, users, groups, ABAC permissions, OAuth, and group mapping.

Identity

Manage access without leaving the product.

Create S3 credentials, assign groups, enforce ABAC permissions, and map OAuth/OIDC claims to DeltaGlider groups from the admin UI.

  • Per-user S3 credentials
  • Groups and ABAC permissions
  • OAuth/OIDC group mapping
live product
DeltaGlider Proxy per-bucket policies page
Product view

Bucket policy surface for compression, aliases, public prefixes, soft quotas, and frozen buckets.

Bucket policy

Control bucket behavior explicitly.

Set compression policy, routing aliases, public read-only prefixes, soft quotas, and read-only freeze at the bucket level.

  • Compression policy
  • Public prefixes and aliases
  • Soft quotas and bucket freeze
Capabilities

Feature map.

Storage efficiency is the core. Access and operations controls make it deployable.
1
Storage
Layer

Reduce backend growth without changing the client contract.

  • S3-compatible API with SigV4
  • xdelta3 delta storage for repeated binaries
  • Filesystem, AWS S3, and MinIO-compatible backends
  • AES-256-GCM proxy-side encryption
2
Access
Layer

Control who can read, write, list, and publish.

  • Per-user IAM and groups
  • ABAC permissions
  • OAuth/OIDC group mapping
  • Public read-only prefixes
3
Operations
Layer

Run the proxy as production infrastructure.

  • Soft per-bucket quotas and bucket freeze
  • Object replication with delete replication
  • Prometheus metrics and embedded dashboard
  • In-memory audit ring and encrypted config DB sync
Use cases

Common deployment paths.

Start with the problem you have today.
Technical proof

Verify the implementation.

Key subsystems are small enough to inspect.

xdelta3 delta engine

Uses the xdelta3 CLI for portable, inspectable deltas and compatibility with the original DeltaGlider format.
src/deltaglider/codec.rs

S3-compatible front end

Supports S3-compatible object workflows including SigV4, ranges, conditionals, copy, multipart uploads, and S3-shaped errors.
src/s3_adapter_s3s.rs

Governance built in

IAM, OAuth, admission, bucket policy, quotas, audit, and config sync are managed through the admin UI and API.
src/api/admin

Rule-based replication

Replication rules, run history, failure records, and continuation state are tracked by the proxy.
src/replication
Next step

Measure it on your data.

Run it beside an existing S3 endpoint and compare original bytes, stored bytes, latency, and cache behavior.
