Contributing to a great open-source library is a great way to establish a portfolio.
I've compiled 23 great open-source libraries and some good first issues to get started with.
DON'T FORGET TO STAR & SUPPORT THESE๐
AI in product๐ฆพ:
1. CopilotKit - In-app AI chatbots and AI Textareas
Open-source platform for integrating key AI features into react apps using two react components.
CopilotPortal: in-app AI chatbots that can "see" the current app state and take actions.
CopilotTextarea: AI-powered replacement. With autocomplete, insertions and generations.
Support bold and italicized text in CopilotTextarea
Proposal:
Add support for bold and italicized text in CopilotTextarea
CopilotTextarea uses slate-js under the hood. Lots of examples for adding bold/italicized support
Initially only add programatic support. UI support will be added separately in [TODO add issue]
Implementation tips:
changes will be made to render-element.tsx and base-copilot-textarea.tsx
custom-editor.tsx structures may also require changes
GPT Researcher is an open deep research agent designed for both web and local research on any given task.
The agent produces detailed, factual, and unbiased research reports with citations. GPT Researcher provides a full suite of customization options to create tailor made and domain specific research agents. Inspired by the recent Plan-and-Solve and RAG papers, GPT Researcher addresses misinformation, speed, determinism, and reliability by offering stable performance and increased speed through parallelized agent work.
Our mission is to empower individuals and organizations with accurate, unbiased, and factual information through AI.
Why GPT Researcher?
Objective conclusions for manual research can take weeks, requiring vast resources and time.
LLMs trained on outdated information can hallucinate, becoming irrelevant for current research tasks.
Current LLMs have token limitations, insufficient for generating long research reports.
Limited web sources in existing services lead to misinformationโฆ
๐น๏ธ Open-source, developer-first LLMOps platform designed to streamline prompt design, version management, instant delivery, collaboration, troubleshooting, observability and more.
Pezzo is a fully cloud-native and open-source LLMOps platform. Seamlessly observe and monitor your AI operations, troubleshoot issues, save up to 90% on costs and latency, collaborate and manage your prompts in one place, and instantly deliver AI changes
In the documentation, you can find information on how to use Pezzo, its architecture, including tutorials and recipes for varius use cases and LLM providers.
Weaviate is an open-source vector database that stores both objects and vectors, allowing for the combination of vector search with structured filtering with the fault tolerance and scalability of a cloud-native databaseโ.
Weaviate
Weaviate is an open-source, cloud-native vector database that stores both objects and vectors, enabling semantic search at scale. It combines vector similarity search with keyword filtering, retrieval-augmented generation (RAG), and reranking in a single query interface. Common use cases include RAG systems, semantic and image search, recommendation engines, chatbots, and content classification.
Weaviate supports two approaches to store vectors: automatic vectorization at import using integrated models (OpenAI, Cohere, HuggingFace, and others) or direct import of pre-computed vector embeddings. Production deployments benefit from built-in multi-tenancy, replication, RBAC authorization, and many other features.
To get started quickly, have a look at one of these tutorials:
LangChain is a framework for building agents and LLM-powered applications. It helps you chain together interoperable components and third-party integrations to simplify AI application development โ all while future-proofing decisions as the underlying technology evolves.
pip install langchain

Add images (or link to the example app) of auth UI helpers Wasp provides
At this point in docs (also in the tutorial if we're using it), it would be nice to add an image of UI helpers for Auth (login/signup form, Google/GitHub button, ...) so developers can immediately see what they are getting and how nice it looks.

Turn on autopilot and deploy and manage Open Source Tools fully automated on Kubernetes. Our Open Source Glasskube Operator is the simplest and fastest way to manage all your favorite Open Source Tools and the related infrastructure components like databases, caches, and keep them up to date without manual hassle.
โจ Features
๐ Easy installation with little to no configuration
โ Automatic setup of databases and caches
๐ Automate and schedule version updates and patches
Connect your local process and your cloud environment, and run local code in cloud conditions.
mirrord lets developers run local processes in the context of their Kubernetes environment
Itโs meant to provide the benefits of running your service on a cloud environment (e.g. staging) without actually
going through the hassle of deploying it there, and without disrupting the environment by deploying untested code
It comes as a Visual Studio Code extension, an IntelliJ plugin and a CLI tool. You can read more about it here.
Heads-up: Weโve rebranded
Starting from 7th November 2025, the Digger project is now OpenTaco.
The companyโs still Digger, same battle-tested engine โ just a more apt name and a bigger vision.
TL;DR
Before: Best-in-class Terraform PR automation (a solid improvement upon Atlantis)
After: The only piece of software you need to run Terraform or OpenTofu in production
We'll gradually update all our marketing material to reflect the same!
CI/CD for Terraform is tricky. To make life easier, specialized CI systems aka TACOS exist - Terraform Cloud, Spacelift, Atlantis, etc.
But why have 2 CI systems? Why not reuse the async jobs infrastructure with compute, orchestration, logs, etc of your existing CI?
Digger runs Terraform natively in your CI. This is:
Secure, because cloud access secrets aren't shared with a third-party
Cost-effective, because you are not paying for additionalโฆ
Horizontal Scroll for CodeBlocks
Currently when reading the dcs, it's not possible to view all of the code for alot of the samples.
Is this the Component rendered across all of the web properties, if so I'll be happy to throw on a horizontal scroll bar that matches supabase branding.
