Every copy of your data, in step.

SyncBlaze moves changes between apps, servers and storage as they happen. One account gives you a real-time sync API, managed server sync, encrypted backups and S3-compatible storage.

Free plan with 5 GB storage and 2 million messages a month. No card needed.

Four services, one sync engine

Each service runs on the same replication core, so a change made in your app, on a server or in a bucket can reach every other place it belongs without glue code.

Real-time Sync API

Shared documents, presence and messaging for web and mobile apps. Clients keep working offline and merge cleanly when they reconnect.

Learn about Real-time Sync API
const doc = blaze.doc("board:42")
doc.on("change", render)
doc.set("cards.c7.title", "Ship v2")

Server & Storage Sync

Replicate folders between servers, regions and buckets. Only the changed blocks move, so a 40 GB folder with a small edit syncs in seconds.

Learn about Server & Storage Sync
blaze sync /var/www/uploads \
  srv-web3:/var/www/uploads \
  --watch --delta

Backups

Scheduled snapshots of servers, databases and buckets, encrypted with your key and locked against deletion. Restore one file or a whole machine.

Learn about Backups
blaze backup create db01 \
  --source postgres://db01/app \
  --every 1h --keep 90d --immutable

S3 Storage

Buckets that speak the S3 API, so your existing tools, SDKs and scripts work by changing one endpoint. Data transfer is included in every plan.

Learn about S3 Storage
aws s3 cp ./report.parquet \
  s3://analytics/2026/11/ \

Built for the boring parts of sync

The work that usually eats a sprint: retries, conflicts, partial uploads, retention rules and restores.

Conflict handling you can predict
Documents merge with CRDTs. File sync lets you choose newest wins, source wins or keep both, per job.
Delta transfer everywhere
Block-level diffs for files and operation logs for documents. You move megabytes, not whole datasets.
Encryption by default
TLS 1.3 in transit and AES-256 at rest. Backups can use a key only you hold.
Regions you choose
Keep data in the EU, the US or Asia. Pin a project to one region or replicate across several.
One bill, clear limits
Every plan lists its limits in plain numbers. Paid plans have published overage rates, and the free plan stops at its cap and never charges you.
API and CLI for everything
Anything you can click in the dashboard, you can script with the REST API or the blaze CLI.

How teams start

  1. Create a projectPick a region and get API keys
  2. Connect sourcesAdd the SDK, install the agent or point at a bucket
  3. Set rulesChoose direction, schedule and retention
  4. Watch it runAlerts, logs and restore tests in one place
