In their own words
Coder
Coder is a self-hosted platform for AI coding agents and cloud development environments running on infrastructure controlled by the customer. Workspaces are defined with Terraform and connect through a secure WireGuard tunnel. Developers can access them through VS Code, JetBrains, Cursor, a web terminal, remote desktop or SSH. Idle workspaces can stop automatically and restart when needed. Coder Agents lets developers delegate development work and research through chat or an API, provisioning a workspace to carry out tasks. Supported model providers include Anthropic, OpenAI, Google, Bedrock and self-hosted endpoints. The agent loop runs in Coder’s control plane, keeping LLM credentials out of workspaces. Coder documents integrations with GitHub, GitLab, Bitbucket and JFrog Artifactory. The Community plan costs nothing and includes unlimited self-hosted workspaces, one platform integration and up to five active agents. Community support is through GitHub and Discord. The CLI is available for Linux, macOS and Windows, alongside API, web and self-hosted platforms.
marimo
marimo is an open-source reactive Python notebook for reproducible experiments, data work, and interactive apps. When a cell runs, dependent cells run as well or are marked stale, helping keep code and outputs consistent. Notebooks are stored as Python files that can be tracked with Git, run as scripts, or reused as modules. Users can build interfaces with sliders, dropdowns, dataframe tables, and selectable plots, then deploy notebooks as interactive web apps or run them in browsers through WebAssembly. SQL cells work with dataframes, databases, CSVs, and Google Sheets, with named backends including Polars, Pandas, PyArrow, DuckDB, SQLite, and Postgres. AI notebook features support OpenAI, Anthropic, Gemini, Ollama, and compatible APIs. marimo has extensions for VS Code and PyCharm, with the VS Code extension also working in Cursor and other VS Code forks. The free hosted option molab provides 4 CPUs, 32 GB RAM, and sessions up to 12 hours; notebooks are public by default. Running notebook code can execute arbitrary code, so the maker advises using trusted notebooks or reviewing code first. The open-source notebook is free.
