Hi and welcome to Star History Weekly #34!
If you‘re new, it's Adela here. Each week, we curate some open-source news and take you to explore an open-source project, the Starlets. Meanwhile, we share fascinating GitHub repos daily over at @StarHistoryHQ, so make sure to follow us if you haven't already.
In Issue #34, we explored 6 projects shaping the "open vs proprietary" landscape.
As proprietary AI softwares like ChatGPT, Midjourney, Perplexity, Claude, Devin, Lovable, VEO continue to dominate the headlines, open-source counterparts are not far behind. Developers and hobbyists wish to take back control: running models locally, avoiding vendor lock-in, and trying out infinite possibilities of customization.
This month, we highlight six outstanding projects shaping the "open vs proprietary" landscape:
LocalAI | the self-hosted GPT API |
ComfyUI | the power user’s Midjourney |
Wan2.2 | cinematic video generation, open and hackable |
OpenHands | the community’s Devin |
Perplexica | the open-source Perplexity AI |
Firecrawl | the building blocks of Lovable-like app builders |
LocalAI is not a model, but an inference layer that wraps open models (LLaMA, Mistral, Gemma, Mixtral, Qwen) behind an OpenAI-compatible API. Developers can swap out OpenAI’s endpoint for LocalAI with minimal code changes.
Strengths: API-compatible, multi-modal (text, embeddings, TTS, images), privacy-friendly, cost-saving.
Limitations: Models still trail GPT-4o and Claude 3.5 in reasoning and creativity. Speed depends on hardware.
👉 The closest open-source alternative to GPT APIs. Not raw parity, but all about control, cost, and freedom.
ComfyUI is a node-based workflow editor for diffusion models. Artists can wire together samplers, ControlNet modules, LoRA models, and video nodes like Lego blocks.
Ecosystem: Hundreds of community plugins and nodes, covering 3D, video, and advanced controls.
Community & Marketing: comfy.org acts as both product site and gallery, showcasing user creations and workflows. Messaging is clear: ComfyUI is for artists of the future.
👉 Midjourney is easy but closed. ComfyUI is harder to learn but infinitely more flexible. Its rise shows creators want control and community, not just outputs.
Developed by Alibaba, Wan2.2 is an ambitious open video generation model. It supports text-to-video, image-to-video, and speech-to-video.
Community: Available on Hugging Face and ModelScope, integrated into ComfyUI workflows, with tutorials and guides shared widely.
Strengths: Motion consistency, cinematic feel, multi-modal inputs.
Limitations: Heavy GPU requirements, occasional artifacts, not plug-and-play.
👉 Proof that open video generation is real — and people are already experimenting with it despite the cost.
Devin sparked huge buzz as the “AI software engineer,” but it’s closed. OpenHands is the community’s open alternative.
Features: AI coding agents that can plan, code, test, debug, and collaborate. Extensible and self-hostable.
Why it matters: Proprietary dev agents are black boxes. OpenHands is transparent and hackable — designed as a collaborative teammate.
Challenges: Early days, far from Devin’s demos, needs ecosystem growth.
👉 The first step toward an open Devin developers can actually use and extend.
Perplexica is an AI-powered search engine that serves as an open-source alternative to Perplexity AI. It combines web search with AI reasoning to provide comprehensive answers with sources.
Features: Real-time web search, multiple AI model support (OpenAI, Ollama, Groq, Anthropic), focus modes for different search types, and chat-based interface.
Self-hosted: Complete control over your search data and AI interactions, with Docker deployment for easy setup.
Limitations: Requires technical setup, dependent on external search engines (SearXNG), and needs API keys for AI models.
👉 The open alternative to Perplexity AI — giving users control over their AI-powered search experience without vendor lock-in.
Firecrawl is an open-source crawler that turns websites into clean Markdown or JSON, perfect for LLMs. To demonstrate its power, the community built Open-Lovable, a clone of Lovable’s instant app builder.
Why it matters: Proprietary app builders hide their stack. Firecrawl shows that the building blocks for Lovable-style apps already exist in open source.
👉 Less about cloning Lovable directly, more about proving you can rebuild it with open infrastructure.
✨ That's September: six open-source projects pursuing giants, each with its own story. The polish may be lacking, but the creativity, vibrancy, and freedom of open source are impossible to ignore.
