Alternatives to TabbyAPI
A lightweight, OpenAI-compatible API server for running ExLlama-format language models on your own hardware. The listings below can replace it for an important use case. Each note says what changes if you switch.
The original
TabbyAPI
A lightweight, OpenAI-compatible API server for running ExLlama-format language models on your own hardware.
Replacements
Listings that take over the same core job as TabbyAPI.
llama.cpp
The C++ engine most local AI apps are built on, running language models on ordinary hardware.
llama.cpp runs GGUF-style quantised models as one binary with a built-in server and web interface, supporting many backends instead of ExLlama format only.
KoboldCpp
A single executable that runs GGUF language models locally, with a web interface and no installation at all.
KoboldCpp is a single executable for GGUF models that exposes OpenAI, Ollama, A1111 and ComfyUI compatible endpoints and includes its own web interface.
TextGen
Chat with local language models using the TextGen desktop interface.
TextGen is an AGPL-3.0 desktop interface that includes API access alongside a built-in chat interface, so no separate front end is required.
Ollama
The simplest way to pull down an open language model and run it on your own machine, from one command or a desktop app.
Ollama downloads and runs models with one command and serves a localhost REST API, removing ExLlama format limits with a desktop app option.
LocalAI
Serve language, image and speech models on your own hardware.
LocalAI is MIT-licensed and serves language, image and speech models with compatible APIs for common services, broader than TabbyAPI's language-model focus.
vLLM
High-throughput, memory-efficient inference and serving engine for LLMs.
vLLM is an Apache-2.0 high-throughput serving engine for Linux, suited to production-scale deployments on appropriate GPU hardware rather than lightweight single-user use.
Xinference
An open-source inference server for running language, speech and multimodal models through one API.
Xinference serves language, speech and multimodal models behind one GPT-compatible API on macOS, Linux or servers, but has no Windows listing.
SGLang
A serving framework for running large language models and multimodal models on your own GPUs.
SGLang is a high-throughput serving framework for language and multimodal models on your own GPU servers, heavier than TabbyAPI's lightweight setup.
Similar software
Related functionality, not a direct replacement.
SillyTavern
A locally-installed front end for language models aimed at long-form roleplay and character-driven writing.
Open WebUI
A self-hosted chat interface that talks to Ollama and any OpenAI-compatible API, so your local models get a proper front end.
KoboldAI Lite
A standalone browser interface for chatting with and writing alongside language models from many backends.
GPUStack
An open-source GPU cluster manager for serving AI models with vLLM and SGLang on your own hardware.
