Meilisearch vs OSQP
A side-by-side editorial comparison of Meilisearch and OSQP — release velocity, themes, recent moves, and the top alternatives to consider.
Meilisearch vs OSQP: at a glance
What is Meilisearch?
Meilisearch shipped 1.52, then spent the same day reverting most of it.
Four releases landed on a single day. Both of 1.52.0's headline items — experimental SSE routes for tasks and batches, and an O(1) rewrite of document formatting — were reverted within a week, in 1.52.2 and 1.52.3. Meanwhile 1.53.0 went out the same day with sharding for foreign filters and new index size statistics. The additions that have actually held are in query capability: dynamic search rules gained filter-based activation conditions in 1.51.0.
What is OSQP?
QP solver that rebuilt its linear algebra layer for GPUs, then went quiet in beta.
OSQP is an operator-splitting quadratic program solver used widely as an embedded optimization backend. Its visible release history stops at the v1.0 beta from May 2023, which was a substantial rework: a pluggable linear algebra backend chosen at compile time, the separate cuOSQP GPU project folded into the main tree, and an Intel MKL backend added. That beta has not been followed by a stable v1.0 in this feed.

◆ Current state
Four releases landed on a single day. Both of 1.52.0's headline items — experimental SSE routes for tasks and batches, and an O(1) rewrite of document formatting — were reverted within a week, in 1.52.2 and 1.52.3. Meanwhile 1.53.0 went out the same day with sharding for foreign filters and new index size statistics. The additions that have actually held are in query capability: dynamic search rules gained filter-based activation conditions in 1.51.0.
◆ Where it's heading
Engine work is pushing along two axes — distributed operation, where foreign filters can now resolve documents across the network and the retrieval limit rose from 100 to 1000, and search-time programmability, where rules can activate on facet filters and pin results. The revert pattern is the other signal: push-based task streaming and the formatting optimization both went out before they were solid, which suggests the release train is running ahead of validation.
◆ Prediction
The reverted SSE streaming routes and the formatting optimization are the obvious candidates to return in a later release once their underlying issues are resolved — neither was withdrawn for lack of intent.
OSQP
0.0DEVOPS
QP solver that rebuilt its linear algebra layer for GPUs, then went quiet in beta.
◆ Current state
OSQP is an operator-splitting quadratic program solver used widely as an embedded optimization backend. Its visible release history stops at the v1.0 beta from May 2023, which was a substantial rework: a pluggable linear algebra backend chosen at compile time, the separate cuOSQP GPU project folded into the main tree, and an Intel MKL backend added. That beta has not been followed by a stable v1.0 in this feed.
◆ Where it's heading
The direction the beta set is clear — OSQP was becoming a solver core that could be retargeted at different compute hardware without changing the algorithm, with CUDA and MKL as the first two targets. Code generation and adjoint derivative computation moving into the C API point the same way, toward embedding OSQP inside other systems including differentiable pipelines.
◆ Prediction
The stable v1.0 is the obvious next milestone, but nothing in these entries indicates when or whether it landed — treat the backend rework as available only in beta form.
