Void is an open-source agentic AI IDE that has been quietly evolving and now has a powerful public release. It is a surprisingly polished and feature-rich alternative to Cursor, Windsurfer, and Copilot that is completely free.

What makes Void stand out is its agentic AI capabilities. Void acts like a pair programmer with goal-driven reasoning and full contextual awareness of your codebase. It can go beyond simple autocomplete and perform autonomous tasks such as searching your codebase, creating, editing, and deleting files, and making structural code changes.

Void offers two distinct AI agent modes to suit your workflow needs:

1. Agent Mode: This is the full-power version that can use any model and is capable of autonomous actions within your codebase.
2. Gather Mode: A safer version designed for users who want more insights without giving the AI broad access. It's ideal for auditing code, answering questions, and working with sensitive environments.

Void supports a wide range of features, including code generation, debugging, and integration with various large language models. You can use free providers like OpenRouter or bring your own API keys from providers like Anthropic and OpenAI.

One of the standout features of Void is its transparency and customizability. You can run it locally, keep your data private, and customize everything to your needs. Void also has a robust set of checkpoints, allowing you to review and approve the changes made by the AI before they are applied.

Overall, Void is a powerful and versatile open-source agentic AI IDE that could seriously change the game in the world of coding assistants. Its combination of advanced capabilities, flexibility, and open-source nature make it a compelling alternative to proprietary tools like Cursor and Copilot.

Void, the open-source agentic AI IDE, offers two distinct AI agent modes to provide flexible and powerful coding assistance:

1. Agent Mode: This is the full-power version of the AI agent. It can use any model and is capable of autonomously searching your entire codebase, creating, editing, and deleting files. It can interact directly within your terminal, automate tasks, and make structural code changes. This mode is similar to Cursor's Composer or Windsurfer's Cascade.

2. Gather Mode: This is a safer version of the agent, designed for users who want more insights without giving the AI broad access. It's ideal for auditing code, answering questions about your project, or working with sensitive environments where safety and transparency are crucial.

Both agent modes provide a wide range of features, including:

• Integrating with any large English model, whether proprietary, Anthropic, or open-source models.
• Offering features like tab completion, quick edit, and an AI-powered chat interface.
• Allowing you to configure the provider, use free models, or connect your own local models.
• Providing checkpoints to visualize the AI's changes and the ability to review and approve or reject them.
• Enabling you to work on tasks like debugging, generating code, and more, with the AI acting as a pair programmer.

Void's flexible agent modes empower you to choose the level of AI assistance that best fits your workflow and project requirements, making it a powerful open-source alternative to Cursor and GitHub Copilot.

Void offers flexibility in choosing your preferred AI model for coding assistance. Here's how you can configure it:

1. Select a Provider: When you first open Void, you'll be prompted to configure the provider. You can choose from free providers like OpenRouter's DeepSC R1 model or paid options like Gemini 2.5 Pro.

2. Connect a Local Model: If you don't want to use a cloud-based provider, you can connect Void to a local model. Void supports integrations with Llama and LLM Studio, allowing you to use your own custom models.

3. Transfer Settings: Void makes it easy to transfer your settings and themes from other IDEs like VS Code, ensuring a seamless transition.

4. Choose the Model: Once you've connected a provider, you can select the specific model you want to use for your coding tasks. Void recommends the Gemini 2.5 Pro preview model for coding-related use cases.

5. Enable Autocomplete: To enhance your coding experience, be sure to enable the autocomplete feature in Void's settings.

6. Set AI Instructions: You can also define custom AI instructions, such as creating a Void rules file, to ensure the AI agent follows your specific guidelines.

With these configurations, you can start leveraging Void's powerful Agentic IDE capabilities, tailored to your preferred AI model and coding preferences.

Void, an open-source agentic AI IDE, offers a powerful alternative to tools like Cursor and GitHub Copilot. Its two distinct AI agent modes - Agent Mode and Gather Mode - provide flexible and powerful coding assistance.

In Agent Mode, the agentic agent can autonomously search your codebase, create, edit, and delete files, and interact directly within your terminal to automate tasks and make structural code changes. This mode is similar to Cursor's Composer or Windsurfer's Cascade.

In Gather Mode, the agent provides insights without granting direct access, making it ideal for auditing code, answering questions about your project, or working with sensitive environments where safety and transparency are paramount.

To demonstrate Void's capabilities, let's use the Agent Mode to generate a SaaS landing page. We'll set the token limit to the maximum and provide the prompt to create the landing page. Void's AI agents will then reason and generate the necessary code snippets, which we can apply to a new directory. The AI will autonomously create the HTML file and other components, and we can review the changes before accepting them.

The resulting landing page is responsive and intuitive, showcasing Void's ability to quickly and efficiently generate code based on your requirements. Void's inline editing, code referencing, and debugging features make it a powerful tool for AI-assisted development.

Void's agentic AI IDE offers powerful capabilities for debugging and editing code. The two distinct agent modes - Agent Mode and Gather Mode - provide flexible assistance depending on your workflow needs.

In Agent Mode, the AI agent can autonomously search your codebase, create, edit, and delete files, and make structural code changes. It interacts directly within your terminal, automating tasks and optimizing your code. This mode is similar to Cursor's Composer or Windsurfer's Cascade, allowing you to leverage the AI as an agentic pair programmer.

The Gather Mode agent, on the other hand, is a safer version designed for users who want more insights without granting the AI full access. This mode is ideal for auditing code, answering questions about your project, or working in sensitive environments where safety and transparency are paramount.

Void's code editing features are similar to Cursor and Windsurfer, allowing you to highlight code snippets, add them to the chat as quotations, and reference multiple files with the act command. You can also make inline edits, leveraging the AI's generation and autocompletion capabilities to enhance your coding workflow.

One of the standout features is Void's diff mode, which allows you to review all the changes the AI has made before executing them. This ensures you maintain control and can approve or reject the suggested modifications, providing an extra layer of safety and transparency.

Overall, Void's autonomous debugging and editing capabilities make it a powerful open-source alternative to Cursor and GitHub Copilot, offering a flexible and customizable solution for your coding needs.

Void, the open-source agentic AI IDE, has emerged as a powerful and feature-rich alternative to proprietary tools like Cursor and GitHub Copilot. With its two distinct agent modes, Void offers flexible and powerful coding assistance tailored to your workflow needs.

The Agent mode provides a full-fledged agentic agent capable of autonomous code manipulation, while the Gather mode offers a safer approach for code auditing and working with sensitive environments. Void's integration with various language models, including proprietary and open-source options, allows users to customize their AI assistant to their preferences.

The platform's active development and frequent updates, backed by Y Combinator, ensure that Void will continue to evolve and improve over time. With its impressive capabilities, Void presents a compelling open-source solution for developers seeking an alternative to the existing AI-powered IDEs on the market.
