GraphHopper vs Apache bRPC
A side-by-side editorial comparison of GraphHopper and Apache bRPC — release velocity, themes, recent moves, and the top alternatives to consider.
GraphHopper vs Apache bRPC: at a glance
What is GraphHopper?
GraphHopper finished moving vehicle profiles into custom models, then went back to OSM tags.
GraphHopper ships a major roughly every six months, with 11.0 in October 2025 the most recent. The architectural work happened in 9.0, which moved vehicle encoded values into the custom model, removed the built-in vehicle parsers' name property and the wheelchair parsers, allowed external encoded values in custom models, and blocked built-in custom model filenames. 10.0 then spent itself on storage layout — byte-based edge storage, a Map-based KVStorage API, wider georef fields — and 11.0 is almost entirely OSM tag interpretation: maxspeed=none handling, separate foot and bike road access, cycleway oneway combinations, toll parsing moved into a country-aware parser.
What is Apache bRPC?
Apache bRPC keeps widening what it can talk to and what it can run on.
bRPC ships a feature release roughly every three months with a consistent shape: a handful of protocol or transport capabilities, a long bugfix list, and steady work on RDMA. Recent releases added native Redis Cluster channel support, a transport layer for protocol extensions, RDMA ECE, SingleIOBuf for FlatBuffers serialisation, RISC-V architecture support, Couchbase CRUD operations, and rate-limited backup request policies. Protobuf compatibility is refreshed almost every cycle, now through v34.

GraphHopper
0.0DEVOPS
GraphHopper finished moving vehicle profiles into custom models, then went back to OSM tags.
◆ Current state
GraphHopper ships a major roughly every six months, with 11.0 in October 2025 the most recent. The architectural work happened in 9.0, which moved vehicle encoded values into the custom model, removed the built-in vehicle parsers' name property and the wheelchair parsers, allowed external encoded values in custom models, and blocked built-in custom model filenames. 10.0 then spent itself on storage layout — byte-based edge storage, a Map-based KVStorage API, wider georef fields — and 11.0 is almost entirely OSM tag interpretation: maxspeed=none handling, separate foot and bike road access, cycleway oneway combinations, toll parsing moved into a country-aware parser.
◆ Where it's heading
The configuration model is settled and the effort has moved to routing quality. Nearly every change in 11.0 is about reading OSM tags more faithfully for a specific mode — bicycle handling on living streets, foot instructions at junctions, MTB speeds on compacted surfaces, HGV tolls by country — which is the long tail of work that separates a routing engine that runs from one people trust. Turn restrictions are the recurring source of real bugs, appearing across 9.0, 10.0, 10.1 and 11.0 with via-way handling repeatedly needing correction. The new POST /navigate endpoint accepting a GraphHopper request is the one API-surface addition in this window.
◆ Prediction
Expect continued profile-level tuning driven by OSM tagging edge cases rather than architectural change, since three consecutive majors have narrowed in that direction. Turn restriction handling with multiple or overlapping via-ways is the most likely source of the next bugfix release, given its record across every version here.
Apache bRPC
0.0DEVOPS
Apache bRPC keeps widening what it can talk to and what it can run on.
◆ Current state
bRPC ships a feature release roughly every three months with a consistent shape: a handful of protocol or transport capabilities, a long bugfix list, and steady work on RDMA. Recent releases added native Redis Cluster channel support, a transport layer for protocol extensions, RDMA ECE, SingleIOBuf for FlatBuffers serialisation, RISC-V architecture support, Couchbase CRUD operations, and rate-limited backup request policies. Protobuf compatibility is refreshed almost every cycle, now through v34.
◆ Where it's heading
Two directions run together. One is reach: more architectures, more backends, more wire protocols, so bRPC can be the single client library inside a heterogeneous fleet. The other is the low-latency path, where RDMA has received polling mode, dynamic block pool expansion and now ECE support across four consecutive releases. The debugging work — bthread naming, configurable stack trace signals, AddressSanitizer support — suggests the users pushing hardest are the ones running it at scale.
◆ Prediction
RDMA has drawn work in every recent release and is the most likely place for the next feature, alongside another Protobuf compatibility refresh.
