Coqui TTS

open sourceexplicit relation

Coqui TTS is an open-source deep learning toolkit for text-to-speech synthesis, originally built by former Mozilla TTS engineers. It supports multi-speaker and multilingual synthesis, voice cloning from just six seconds of audio, and ships pre-trained models for 20+ languages. After Coqui shut down in 2023, the Idiap Research Institute forked and actively maintains it. With 45K+ GitHub stars, it remains the most popular open-source TTS framework in Python.

Coqui TTS is a 100% free and open-source deep learning toolkit for text-to-speech licensed under MPL 2.0, maintained by the community following Coqui AI's closure. There are no paid tiers or commercial subscription plans.

VoxCPM

open sourceexplicit relation

VoxCPM is an open-source text-to-speech system from OpenBMB generating continuous speech across 30 languages without traditional tokenization. Its 2B parameter end-to-end diffusion architecture produces 48kHz studio-quality audio with natural prosody and emotion. Key capabilities include voice design from text descriptions, few-shot voice cloning, and multilingual synthesis without language-specific modules. The Apache 2.0 project has 8,700 GitHub stars.

Free and open-source under the Apache-2.0 license. Pretrained models can be run locally or self-hosted with no software fees.

RayRay is an open-source distributed computing framework built for scaling AI and Python applications from a laptop to thousands of GPUs. It provides libraries for distributed training, hyperparameter tuning, model serving, reinforcement learning, and data processing under a single unified API. Ray's public site highlights OpenAI and other enterprise users. Maintained by Anyscale with Apache-2.0 open-source licensing.LLaMA-FactoryLLaMA-Factory is an open-source toolkit providing a unified interface for fine-tuning over 100 LLMs and vision-language models. It supports SFT, RLHF with PPO and DPO, LoRA and QLoRA for memory-efficient training, and continuous pre-training. The LLaMA Board web UI enables no-code configuration, while CLI and YAML workflows serve advanced users. Integrates with Hugging Face, ModelScope, vLLM, and SGLang for model deployment.TavilyTavily is an AI-native search API that provides real-time web search, content extraction, and crawling capabilities specifically designed for LLM applications and autonomous agents. It returns structured, citation-ready results optimized for RAG workflows with built-in safety features including prompt injection protection and PII leak prevention. Acquired by Nebius in 2026, Tavily integrates with LangChain, LlamaIndex, and major agent frameworks, serving over one million developers worldwide.FirecrawlFirecrawl is a Y Combinator-backed API that crawls websites and converts them into clean, LLM-ready Markdown or structured JSON. Handles JavaScript rendering, pagination, sitemaps, and anti-bot measures automatically. Designed for RAG pipelines, AI agents, and data extraction workflows. Features batch crawling, scheduled scraping, webhook notifications, and custom extraction schemas. Processes content for direct ingestion into vector databases and LLM context windows.UnslothUnsloth is an open-source framework for fine-tuning large language models up to 2x faster while using 70% less VRAM. Built with custom Triton kernels, it supports 500+ model architectures including Llama 4, Qwen 3, and DeepSeek on consumer NVIDIA GPUs. Unsloth Studio adds a no-code web UI for dataset creation, training observability, model comparison, and GGUF export for Ollama and vLLM deployment.VibeVoiceVibeVoice is Microsoft's open-source voice AI family with both TTS and speech recognition models. The TTS model generates up to 90 minutes of expressive multi-speaker audio with 4 distinct voices. VibeVoice-ASR transcribes 60-minute recordings in a single pass with speaker identification and timestamps. Built on continuous speech tokenizers at 7.5 Hz and next-token diffusion, it compresses audio 80x more efficiently than Encodec while preserving fidelity.HelixDBHelixDB is an open-source, unified graph-vector database engineered in Rust that merges relational, graph, and vector workloads into a single OLTP engine, using LMDB local caching and S3 object storage for scalable agent memory.Microsoft GraphRAGMicrosoft GraphRAG is an open-source retrieval framework that transforms unstructured text into structured knowledge graphs, clusters entities hierarchically using the Leiden algorithm, and generates dataset-wide summaries alongside entity-level local search for multi-hop reasoning.MetabaseMetabase is an open-source business intelligence and embedded analytics platform for teams that want self-service dashboards, SQL workflows, and customer-facing analytics without adopting a heavy BI suite.
