Prerequisites
GitHub account with OAuth access for repository operations.
A model API key (Anthropic, OpenAI, or compatible provider).
A LangSmith API key when using LangSmith as the sandbox provider.
Slack workspace, Linear workspace, or GitHub repository access for the desired trigger integrations.
## Overview
Open SWE is a practical reference implementation for teams that want to run
coding agents against their own repositories without building the orchestration
layer from scratch. It mirrors patterns used by engineering teams at Stripe,
Ramp, and Coinbase for internal coding agents.
The framework composes on LangGraph and the Deep Agents harness. Each task
runs in a dedicated cloud sandbox (Modal, Daytona, Runloop, or LangSmith),
executes the agent loop with roughly fifteen curated tools, and opens a draft
PR on completion. Parallel tasks get separate sandboxes with no queuing.
## Features
- Multi-platform invocation through Slack mentions, Linear comments with
`@openswe`, and GitHub PR comment replies.
- Isolated, reusable cloud sandboxes per task thread with pluggable providers
(Modal, Daytona, Runloop, LangSmith).
- Automatic draft pull request creation and linking back to the source task.
- Subagent orchestration for parallel subtasks via the `task` tool.
- Configurable model support and a curated tool set covering shell execution,
file operations, web fetches, and API requests.
- A web dashboard for authentication, team settings, and direct agent chat.
## Use Cases
- Triage and resolve routine engineering tasks raised in Linear or Slack.
- Stand up an internal coding agent that respects organization conventions via
an `AGENTS.md` or `CLAUDE.md` context file.
- Run multiple coding tasks in parallel without manual environment setup.
- Prototype a customizable, self-hosted alternative to closed coding agents.

Open-source framework for building internal coding agents that accept tasks via Slack, Linear, or GitHub, execute code changes in isolated cloud sandboxes, and open draft pull requests automatically.
Open-source infrastructure for securely running AI-generated code in isolated sandboxes that start in milliseconds, with SDKs for Python, TypeScript, and other languages, persistent snapshots, and an optional managed cloud.
✓Each task runs in an isolated cloud Linux sandbox (Modal, Daytona, Runloop, or LangSmith) to prevent production impact.
The agent executes shell commands, file operations, web fetches, and HTTP requests inside the sandbox without confirmation prompts — review sandbox provider permissions before deployment.
GitHub operations are performed through a GH_TOKEN proxy; scope token permissions to the minimum required repositories.
Subagent orchestration can spawn parallel child agents — set appropriate step limits and monitor LangSmith traces to prevent runaway execution.
AGENTS.md or CLAUDE.md at the repository root is injected into the system prompt; review this file to control agent behavior and conventions.
✓Daytona is purpose-built to execute arbitrary, AI-generated code; only run untrusted code inside its isolated sandboxes, never on the host.
Each sandbox has its own kernel, filesystem, and network stack, but sandboxes can make outbound network requests unless network limits are configured.
Sandboxes support computer use, Git operations, and command execution; scope what an agent can do and review declarative builder configurations before use.
Self-hosting runs runner compute nodes and Docker services that need elevated host privileges; isolate the deployment from production systems.
Persistent snapshots retain sandbox filesystem state across sessions, which can preserve secrets or sensitive files written during execution.
— missing
✓OpenHands agents can edit files, run terminal commands, browse websites, start servers, and interact with repositories, so each workspace needs a clear permission boundary.
The documentation recommends Docker sandboxing for local use; process-based execution is faster but has no container isolation and should be treated as unsafe for sensitive projects.
Mounts into the sandbox can be modified by the agent when granted write access, so avoid broad host mounts and review exactly which project files are exposed.
Confirmation mode and security analyzers can reduce risk by pausing high-risk actions, but they do not prove that an action is correct, reversible, policy-compliant, or safe to merge.
Hosted, cloud, enterprise, and integration workflows add additional access-control, audit, retention, budget, and organization-policy requirements beyond the local open-source project.
Benchmark performance, agent planning, context compression, and security analysis are useful signals, but human review is still required before generated changes affect protected branches or production systems.
Privacy notes
✓Repository code, Linear issue history, and Slack thread history are sent to the configured model provider API.
Sandbox providers (Modal, Daytona, Runloop, LangSmith) process task execution data according to their own privacy policies.
LangSmith tracing, when enabled, logs full agent traces including tool inputs and outputs — configure retention and access controls in your LangSmith organization.
GitHub OAuth tokens and model API keys should be stored as secrets and never committed to the repository.
✓Using the managed cloud sends your code, files, and execution data to Daytona-operated infrastructure; review their terms before processing sensitive data.
The platform emits OpenTelemetry metrics, log streaming, and audit logs that can capture command output and activity.
API keys grant access to your sandboxes and organization; store them as secrets and never commit them to source control.
Self-hosting keeps execution data on your own infrastructure but you become responsible for log retention, access control, and isolation.
— missing
✓OpenHands may process prompts, issue text, source snippets, diffs, terminal output, browser context, logs, traces, uploaded files, repository metadata, and generated patches.
Model providers, local model routes, OpenHands Cloud, enterprise deployments, or connected gateways may receive task context depending on the selected configuration.
Local GUI, CLI, SDK, and sandbox workflows can save conversation history, workspace state, logs, screenshots, browser artifacts, and server output on the machine or managed workspace.
Cloud and enterprise integrations with GitHub, GitLab, Bitbucket, Slack, Jira, and Linear should be reviewed for repository access, user identity, issue data, retention, and audit visibility.
Operators should define retention and redaction rules before sharing OpenHands conversations, trajectories, screenshots, generated patches, or benchmark artifacts outside the project team.
Prerequisites
GitHub account with OAuth access for repository operations.
A model API key (Anthropic, OpenAI, or compatible provider).
A LangSmith API key when using LangSmith as the sandbox provider.
Slack workspace, Linear workspace, or GitHub repository access for the desired trigger integrations.
A Daytona Cloud account and API key for the managed service, or self-hosted infrastructure for the open-source platform.
Python 3.8+ for the `daytona` SDK or Node.js 18+ for the `@daytona/sdk` TypeScript SDK.
Docker and Docker Compose to run supporting services (PostgreSQL, Redis) when self-hosting.
Nix with flakes enabled or a devcontainer-compatible editor for local development of the platform itself.
— none listed
Supported local system, container setup, or managed workspace for running the OpenHands local GUI, CLI, SDK, or hosted workflow.
Docker Desktop, Linux container environment, WSL setup, or remote sandbox plan when using the recommended isolated local execution path.
Approved model provider, local model, or hosted model route configured with the organization controls, spend limits, and data handling rules required for the target repository.
Git provider access, repository permissions, branch strategy, review ownership, and rollback plan before connecting OpenHands to real issues, pull requests, or production codebases.
