Overview
DataCourier abstracts sending and receiving framed data over multiple protocols. You pick a protocol, a packet rule (fixed length, size+body, terminator…) and a delivery box that marshals typed payloads.
Fork note Modules
ObjectDeliverer / ObjectDelivererTests were renamed to DataCourier* for UE 4.27–5.0+, with CoreRedirects for content. Several UE5-only APIs (EAllowShrinking, FProperty/object helpers, a WebSocket binding) were ported to 4.27–5.0+ and a conversion helper library was added.Requirements
| Requirement | Details |
|---|---|
| Unreal Engine | 4.27–5.0+ |
| Language | Blueprints and/or C++ |
| Platforms | Win64 · Mac · Linux |
Installation
- Copy the
DataCourierfolder into your project'sPlugins/directory. - C++ projects: regenerate project files and build. Blueprint-only projects can launch the editor directly.
- Open Edit → Plugins and confirm DataCourier is enabled.

Utility node pack
General-purpose networking utilities added to UDataCourierUtilityLibrary — available from Blueprints and C++.
| Node | Type | Description |
|---|---|---|
| CRC32 Of Bytes | Pure | CRC32 checksum of a byte array. |
| MD5 Of String / SHA1 Of String | Pure | Hex digests of a UTF-8 string. |
| Make Guid String | Pure | New random GUID (hyphenated). |
| Now Unix Seconds | Pure | Current UTC time as Unix seconds. |
| Unix Seconds To ISO8601 | Pure | Unix seconds → ISO-8601 UTC string. |
| Format Byte Size | Pure | Human-readable size, e.g. 1536 → 1.5 KB. |
| Random Token | Pure | Random alphanumeric token (ids, nonces). |
| XOR Bytes With Key | Pure | XOR bytes with a repeating key (obfuscation, not encryption). |
| Is Valid Hostname | Pure | RFC-952/1123-style hostname validation. |
