About

Jcode is an open-source AI coding agent developed by Solo Systems, purpose-built for the terminal environment. It goes far beyond simple code completion, functioning as an intelligent assistant that can independently understand, plan, and execute coding tasks. Equipped with long-term memory, side panels, background task support, and multi-agent swarm coordination, jcode enables developers to complete everything from code generation to project maintenance without ever leaving the command line. As a fully open-source product, jcode gives developers a high degree of control and customization, making it a powerful tool for boosting coding productivity.

Key Features

Terminal-native operation: Launch and interact directly from the command line with no need to switch to a graphical interface, keeping developers fully focused.

Built-in memory system: Jcode remembers project context, user preferences, and historical actions, automatically referencing relevant information in later tasks to reduce repetitive explanations.

Side panel support: Provides an in-terminal information panel that displays code diffs, file structures, task progress, and other auxiliary content in real time for better visibility.

Background task execution: Long-running tasks such as tests, builds, and deployments can run in the background while users continue other work without interruption.

Swarm coordination: Multiple jcode agents can work together in parallel to handle complex modules or divide up large projects, enabling team-level automation.

Pricing & Fees

Pricing: Monthly token plans from $10 to $1,000; each plan grants double its price in inference credit (e.g., $20 of credit on the $10 plan) plus Jcode Cloud access. The agent itself is open source and free to self-run with your own models.
Free use: The open-source agent can be used at no cost if you bring your own model API keys; hosted inference and cloud features are optional paid extras.
Free trial: The first month of the $20 plan is free and includes 5,000 remote Rust builds; a card is required and it renews at $20/month unless canceled. Inference credit starts with the first paid month.
Plan details: Every $10 of plan value includes 50 Jcode Cloud machine hours per month; remote Rust builds start at the $20 plan (2,500 builds per $10, so $20 gets 5,000/month). Extra builds cost $0.10 each.
Billing quirks: Monthly credit does not accumulate, and inference beyond credit is billed at provider API prices only if you raise the extra usage limit, which defaults to $0 per month.

Who It's For

Jcode is ideal for independent developers who want to cut down on repetitive coding work and focus on core logic; full-stack engineers juggling frontend, backend, and database modules who need parallel task handling; open-source contributors who need help with code review, test generation, and documentation maintenance on large projects; and DevOps engineers who can leverage background tasks and swarm coordination to automate deployment, monitoring, and infrastructure management workflows.
