GraphHopper vs Weaviate
A side-by-side editorial comparison of GraphHopper and Weaviate — release velocity, themes, recent moves, and the top alternatives to consider.
GraphHopper vs Weaviate: 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 Weaviate?
Weaviate ships Engram agent memory, HFresh disk indexing, and 4-bit quantization in quick succession
Weaviate 1.39 is the current stable release, having GA'd the Boost API and MMR diversity selection while introducing an experimental Search REST API. Two major storage advances landed in rapid succession: HFresh, a disk-based vector index that keeps vectors off the heap entirely, and 4-bit Rotational Quantization, which compresses stored vectors with minimal accuracy loss. Above the storage layer, Engram — a named agent memory product — is the most significant architectural addition: it lets builders configure extraction topics, scopes, and retrieval modes as first-class settings rather than building memory pipelines by hand.

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.

Weaviate ships Engram agent memory, HFresh disk indexing, and 4-bit quantization in quick succession
◆ Current state
Weaviate 1.39 is the current stable release, having GA'd the Boost API and MMR diversity selection while introducing an experimental Search REST API. Two major storage advances landed in rapid succession: HFresh, a disk-based vector index that keeps vectors off the heap entirely, and 4-bit Rotational Quantization, which compresses stored vectors with minimal accuracy loss. Above the storage layer, Engram — a named agent memory product — is the most significant architectural addition: it lets builders configure extraction topics, scopes, and retrieval modes as first-class settings rather than building memory pipelines by hand.
◆ Where it's heading
Weaviate is executing a two-layer expansion: at the bottom, making the vector store cheaper and more flexible (quantization, disk-based indexing, query profiling); at the top, building agent-native abstractions that make Weaviate more than a search backend (Engram memory, effort tiers, Search REST API). The direction has shifted from 'fast vector database' toward 'infrastructure for AI agent memory and retrieval systems.' The consistent release of deep technical content alongside product updates suggests the team is deliberately targeting developers building production agent systems, not just evaluating vector databases.
◆ Prediction
Engram moving from guide to GA release is the most predictable next step. The experimental Search REST API, introduced in 1.39, is also positioned to stabilize — and the growing late-interaction retrieval work (multi-vector for PDFs and charts) looks like the foundation of a more formal multi-modal retrieval product rather than staying at the technique level.
