CELERiS is engineered on proven, open foundations - benefit first, technology to last. Whether you need a ground-up replacement to retire costly proprietary systems, or an open foundation you truly own with guaranteed data sovereignty, no per-seat licences and no vendor lock-in, CELERiS provides a scalable, self-hostable infrastructure built on modern standards.
CELERiS is built on a high-performance stack designed for scale, resilience, and uncompromised speed.
A multi-crate workspace across core, providers and tooling. Memory-safe, fearless concurrency, no GC pauses on real-time feeds.
Async Rust web framework and runtime - the performance substrate providing real-time guarantees.
Industry-standard spatial database for geospatial queries at scale.
Compact, wire-friendly binary format (prost / tonic) for constrained links and small devices.
Our transmission-independent mesh communications layer - offline-first data exchange for providers, staff, riders and the public.
Our specialised Rust journey-planning engine for extreme multimodal complexity - sub-millisecond, local-first routing for people and goods, no cloud dependency required.
Our nested-dissection road-routing overlay - fast, customisable road-network routing with offline-first boundary tiles built in.
The open specification CELERiS is a reference implementation of - one model for people and goods across every mode, not a proprietary silo. Read the spec ↗
The Accessibility system models movement inside a hub - accessible path segments, traveller profiles, live lift/ramp/beacon status and assistance requests - so CELERiS generates point-to-point directions that work for any ability, for people and goods alike.
Dangerous Goods implements the UN Recommendations on the Transport of Dangerous Goods (Model Regulations) - UN numbers (e.g. UN1203) and proper shipping names, hazard classes 1–9, packing groups I–III, and built-in segregation and compatibility rules (so Class 1 explosives never travel with Class 3 flammable liquids). A regional map layers on localised standards like ADR, US DOT and IATA tunnel codes and variations.
The Logistics system models the container and freight side end to end - Shipment for full shipment-level declarations and ShippingUnit (FreightItem) for individual parcels, pallets and shipping containers - plus inventory management and multi-modal logistics chains across air, ground, maritime and space.
One example of the source standards we adapt into OpenJourney - alongside maritime, aviation and freight/logistics feeds. We speak the standards you already use.
Open, interoperable geometry in and out, on the core and the map clients.
Maritime AIS and aviation ADS-B providers - concrete proof of the multimodal claim.
A uniform plugin contract - add a data source as an isolated crate or an out-of-process runner.
One completion abstraction over multiple backends - bring your own model, no vendor lock-in.
An MCP server for AI agents - current, composable tooling for the AI-agent era.
Topic-threaded team chat deployed under the Tabula workspace, configured against the shared PostgreSQL cluster - no prohibited databases.
Self-hosted file collaboration with Euro-Office wired in as a Nextcloud Office (WOPI) integration for web-based collaborative document editing, tied into Tabula’s SSO/HR directory.
Custom
Compose/Kubernetes
manifests use named
Docker volumes seeded by
init-containers (e.g.
tabula-config-loader
) - no host bind-mounts.
A Rust bridge crate relays critical Zulip topics and Nextcloud alerts to offline field devices over the Wayfarer BLE gossip protocol.
Native Android and desktop apps from one codebase.
A modern, fast web client toolchain.
Open-source mapping - no proprietary map-tile lock-in.
Optional tiles, routing and live traffic from Google Maps, Waze, HERE, TomTom and Mapbox - plugged in where customers want them, never required.
Interoperable with Esri ArcGIS and QGIS so geospatial teams can bring their own layers, basemaps and analysis.
One storage API over local disk, S3, GCS, Azure and more - swap backends with zero code change.
The whole stack is containerised and runs on amd64 and arm64, down to a Raspberry Pi 4.
A complete generated chart with Ingress and autoscaling.
Generated modules for AWS, GCP and Azure that provision managed PostGIS / Redis, then deploy the chart.
Enterprise SSO and OAuth2 - the auth checkbox big customers care about.
One journey data fabric across the whole spectrum - the same protocol and data model whether it’s a field sensor or a managed cloud cluster.
Providers already ingest the telemetry IoT produces - AIS vessel transponders, ADS-B aircraft and AVL/GPS vehicle feeds.
Celeris speaks Protobuf - a compact binary format purpose-built for constrained links and small devices.
The provider-neutral, out-of-process runner is the natural seam where a fleet of field devices becomes “just another provider” feeding the core.
The whole stack is multi-arch and runs down to a Raspberry Pi 4 - the lower-bound proof point, available now.
A
no_std
firmware SDK for
MCU-class hardware
(ESP32 / RP2040 / STM32)
and a tiny on-device
CELERiS agent are on the
horizon.
Vendor-neutral interop over Matter so CELERiS can surface alongside Home Assistant, Google Home, Apple Home and Amazon Home in the places people live and work.
We're ready to help. We can walk your team through the architecture and map out how it fits your specific stack.
