vLLM
Best alternatives to vLLM in 2026
Serving a large language model to real users is expensive and technically tricky: naive approaches waste huge amounts of GPU memory and can't handle many simultaneous requests efficiently. vLLM is an open-source inference engine, originally developed at UC Berkeley, built specifically to solve this — it lets you deploy LLMs that respond faster and serve more users per GPU than most alternative setups. Its core innovation, PagedAttention, manages GPU memory the way an operating system manages RAM, enabling continuous request batching and prefix caching. It exposes an OpenAI-compatible API, supports 200+ model architectures, multiple quantization formats (FP8, INT8, INT4, GPTQ, AWQ, GGUF), speculative decoding, multi-LoRA and structured output generation, and works across a broad range of hardware. It's entirely free and open-source under Apache-2.0, with 2,000+ active contributors and adoption by major AI organizations in production.

#3
Lets you build automations by describing them in plain English instead of dragging boxes around a workflow canvas, then connects them to tools like Slack, Notion or Google Sheets.
genfuseai.com
- ✓ Construction d'automatisations par description en langage naturel, pas de canvas visuel
- ✓ Agents IA capables de raisonnement et d'autocorrection, pas seulement du if-then
#4
Gives AI agents a real memory and a private workspace so they stop forgetting everything between conversations and re-reading the same documents over and over.
exabase.io
- ✓ Mémoire persistante avec extraction automatique de faits et résolution des contradictions
- ✓ Temps de réponse inférieur à 300ms selon l'éditeur
#5
Lets a company build one AI agent that lives inside Slack, GitHub, Linear and other tools it already uses, instead of juggling separate AI features bolted onto each app.
adapt.com
- ✓ Un seul agent partout au lieu d'IA fragmentées par outil
- ✓ Routage multi-modèles avec failover en cas de panne fournisseur
#6
A privacy-first LLM gateway that routes requests across 600+ models without logging prompts, verified via a Trusted Execution Environment.
trustedrouter.com
- ✓ Cryptographically verifiable no-logging via TEE attestation, not just a policy claim
- ✓ OpenAI-compatible API — easy migration from existing integrations
#7
Turns OpenAPI specs into safe, typed tools that AI agents can call, without manual wiring.
github.com
- ✓ Generates typed, ownable code instead of a runtime black box
- ✓ Automatic read/write/destructive risk classification
#8
Open-source enterprise AI platform connecting company knowledge across 50+ apps with permission-aware search.
pipeshub.com

#10
A public message board built for AI agents rather than humans — any agent can post a note, request, or result by hitting a URL, with zero setup, no SDK, and no account.
swarmmemo.com
- ✓ Poster ne demande qu'une requête GET, aucun setup
- ✓ Types de messages structurés + salons + flux Atom
#11
An unofficial REST API that lets developers generate Midjourney images from code instead of Discord, with webhooks, polling, and SDKs — since Midjourney itself doesn't offer a public API.
midjourney-api.com
- ✓ Accès API à Midjourney sans passer par Discord
- ✓ Webhooks et polling, SDK Python/Node.js
#12
A policy-bound cloud coding agent that works on isolated, pinned environments and delivers changes as pull requests, with an encrypted audit trail.
