What is Bun?

Bun rewrote its entire runtime from Zig to Rust and shipped HTTP/2 server support in v1.4.

Bun made two foundational moves in 2026: a complete Zig-to-Rust rewrite announced in July, and a v1.4.1 release that ships HTTP/2 server support in Bun.serve, workspace-scoped node_modules, argon2 in crypto, tree-shaking through dynamic imports, and a 9x throughput gain on Buffer I/O. The runtime now handles most production server workloads that previously required Node.js.

What is Manticore Search?

Manticore 29.9 ships chunked multi-vector embeddings and mmap column access, closing gaps with dedicated vector DBs.

Manticoresearch is releasing at high cadence, shipping major capabilities alongside a stream of correctness fixes. The 29.9.0 release consolidates chunked auto-embeddings with multiple strategies (mean, fixed, recursive, sentence), float_vector_array for multi-vector document storage, mmap-based columnar attribute access, and AWS credential-chain backup authentication — all in a single open-source artifact. The 29.8.x series concurrently fixed hybrid search correctness, Elasticsearch-compatible bulk error handling, and RT table embedding metadata.

Bun vs Manticore Search: editorial side-by-side

5.0

Bun rewrote its entire runtime from Zig to Rust and shipped HTTP/2 server support in v1.4.

◆ Current state

Bun made two foundational moves in 2026: a complete Zig-to-Rust rewrite announced in July, and a v1.4.1 release that ships HTTP/2 server support in Bun.serve, workspace-scoped node_modules, argon2 in crypto, tree-shaking through dynamic imports, and a 9x throughput gain on Buffer I/O. The runtime now handles most production server workloads that previously required Node.js.

◆ Where it's heading

Bun is methodically closing Node.js compatibility gaps while building APIs Node.js does not have — Bun.Image, Bun.cron, Bun.WebView, HTTP/2+3 support. The Rust rewrite signals long-term commitment to safety and contributor ecosystem depth that Zig could not provide. At this pace, a v2.0 major is the next logical milestone to formalize the built-in API surface.

◆ Prediction

A 2.0 major release will likely stabilize the HTTP/2 and HTTP/3 server story and formalize the Bun.Image and Bun.cron APIs as supported. The Rust migration should produce measurably lower crash rates in subsequent releases.

M7.5

Manticore 29.9 ships chunked multi-vector embeddings and mmap column access, closing gaps with dedicated vector DBs.

◆ Current state

Manticoresearch is releasing at high cadence, shipping major capabilities alongside a stream of correctness fixes. The 29.9.0 release consolidates chunked auto-embeddings with multiple strategies (mean, fixed, recursive, sentence), float_vector_array for multi-vector document storage, mmap-based columnar attribute access, and AWS credential-chain backup authentication — all in a single open-source artifact. The 29.8.x series concurrently fixed hybrid search correctness, Elasticsearch-compatible bulk error handling, and RT table embedding metadata.

◆ Where it's heading

The engine is systematically replacing external dependencies for AI workloads. Native chunking means no upstream text-splitting service, auto-embeddings with configurable input limits means no external embedding pipeline, and float_vector_array means no separate vector database for chunk-level retrieval. Manticore is positioning as the single system that ingests, chunks, embeds, and searches — a self-hosted alternative to a Qdrant or Weaviate stack that requires orchestrating multiple services. The cloud-aware backup additions suggest it's also targeting managed deployments.

◆ Prediction

The hybrid search correctness fixes in 29.8.x reveal active work on BM25+KNN fusion. The next likely move is a configurable retrieval reranker or a scoring blend API that lets applications tune the balance between lexical and vector relevance without writing fusion code themselves.
