Open-source Devin alternatives in 2026

The closest open-source equivalents to Devin in 2026 are OpenHands (autonomous agent platform, MIT core), Waynode (self-hosted agent workspace, MIT), and a set of bring-your-own-key agents (OpenCode, Goose, Cline, Aider, and mini-SWE-agent) that run on your own machine with any model. None is a drop-in Devin clone; each covers a different slice of "an AI engineer that works while you don't", and all of them let you keep code, credentials, and model spend under your own control.

TL;DR

• OpenHands is the most direct open-source Devin analogue: an autonomous agent with a web UI, self-hosted via Docker, ~80k GitHub stars.
• Waynode is not an autonomous-engineer clone; it is a self-hosted workspace where an agent works in a real cloned repo you can return to from any device, including a phone.
• OpenCode, Goose, Cline, and Aider are local, developer-driven agents: free software, you pay only for model tokens.
• mini-SWE-agent is the research-grade option: ~100 lines of agent code scoring >74% on SWE-bench Verified.
• Devin's self-serve plans now run Free, Pro $20/mo, Max $200/mo, and Teams $80/mo plus $40 per developer seat, with auto-refreshing usage quotas and API-priced overages (devin.ai/pricing). The open-source case is control and cost transparency more than price.

What does "Devin alternative" actually mean?

Devin is a hosted autonomous software engineer: you give it a task, it plans, edits, runs tests, and opens a pull request inside Cognition's cloud. Billing is quota-based: each paid plan includes a usage allowance that refreshes automatically, with overages purchased at API pricing (devin.ai/pricing); the earlier ACU-denominated Core and Team plans were retired in April 2026 (Cognition announcement). An open-source alternative can replace different parts of that:

• The autonomous loop: an agent that takes an issue and drives it to a PR (OpenHands, mini-SWE-agent).
• The workspace: a durable place where agent runs, diffs, branches, and terminal state live and persist (Waynode).
• The pair-programming layer: an agent you steer interactively in a terminal or editor (OpenCode, Goose, Cline, Aider).

Deciding which slice you need matters more than any ranking. The list below is ordered by how directly each tool substitutes for Devin's core promise. For a head-to-head with Devin itself, see /compare/waynode-vs-devin.

Comparison table

1. OpenHands: the most direct open-source Devin

OpenHands (formerly OpenDevin) began as an explicit open-source answer to Devin and has grown into what its repository now calls a "self-hosted developer control center for coding agents": a web UI from which you can run the OpenHands agent (or Claude Code, Codex, and Gemini agents) against your projects, with Docker-sandboxed execution (github.com/OpenHands/OpenHands, ~80k stars as of mid-2026). The core is MIT-licensed and free to self-host with your own LLM key; a single docker run starts the web UI locally.

Licensing gets more complicated beyond the core: the managed OpenHands Cloud has a free-to-start individual tier with at-cost model pricing, while the self-hosted Cloud distribution (a Helm chart for Kubernetes) ships under a Polyform Free Trial license limited to 30 days per year without a commercial agreement, and multi-user enterprise deployments are custom-priced (openhands.dev/pricing, openhands.dev blog). If you want a free, fully open path, that is the MIT single-user version.

Pick it when: you want issue-to-PR autonomy on your own infrastructure and are comfortable operating Docker and managing model keys.

2. Waynode: a self-hosted workspace, not a Devin clone

Waynode takes a different position: it is not an autonomous software engineer you fire tasks at. It is an MIT-licensed, self-hosted coding-agent workspace. Each workspace is a real cloned Git repository on disk (a persistent worktree, not a disposable task container), and the agent (the open-source pi engine, with pi-codex-goal for autonomous goal runs) works inside it. Changed files, hunks, commits, branches, and push controls sit beside the conversation, so "done" means ready for review rather than merely finished running.

Two properties distinguish it from everything else on this list. First, persistence: conversation, files, branches, and terminal state survive between visits, so a task started at a desk can be resumed later from another device. Second, mobile: the same workspace, session, and diff render on a phone, so you can follow a live run, review changed files, steer the agent, and push a reviewed change from wherever you are. Self-hosting starts by cloning the repo and running ./scripts/self-host.sh setup; the guided installer asks for a GitHub or GitLab OAuth app and your model-provider key before it validates and starts Docker Compose. A managed option, Waynode Cloud, runs the same open-source stack from $39/mo (Starter: 3 seats, 3M agent tokens, 10 GB) with a 15-day free trial.

Pick it when: you want a durable, reviewable place where agent work happens in your actual repo, especially if you want to check on and steer runs from a phone. Skip it if you specifically want fire-and-forget issue-to-PR autonomy with no review loop; OpenHands is closer to that. See /learn for how Waynode fits alongside cloud agents.

3. OpenCode: the terminal-native option

OpenCode is an MIT-licensed coding agent built for the terminal. It is the most-starred repository in the category, with roughly 185k GitHub stars as of mid-2026 (github.com/anomalyco/opencode), and supports 75+ LLM providers, from Anthropic and OpenAI (including ChatGPT subscription accounts) to local models (opencode.ai). You launch it in a project directory, describe a task, and it searches, edits, and runs commands, pausing for review. It is interactive by design (closer to Claude Code than to Devin), but the provider breadth and MIT license make it a common self-hosted foundation.

Pick it when: you live in the terminal and want maximum model flexibility with zero platform lock-in.

4. Goose: foundation-governed desktop and CLI agent

Goose started at Block (block.xyz announcement) and is now hosted under the Linux Foundation's Agentic AI Foundation; its repository lives in the aaif-goose organization. It is Apache-2.0, written in Rust, ships as a desktop app, CLI, and API, works with any LLM including local models, and extends through MCP integrations. It is a general-purpose agent rather than a pure software engineer, which cuts both ways: broad automation reach, less repo-workflow specialization.

Pick it when: you want an open-governance agent that handles coding plus adjacent automation, on-device.

5. Cline: the VS Code route

Cline is an Apache-2.0 autonomous coding agent that lives primarily in VS Code, with a CLI and an open-source SDK exposing its agent harness (github.com/cline/cline). It is bring-your-own-key: you connect Anthropic, OpenAI, Bedrock, Vertex, or OpenRouter credentials and pay the provider directly, so the extension itself costs nothing. It inspects the project, edits files, runs commands, and drives a browser, asking permission at each step.

Pick it when: your team works in VS Code and wants agentic edits with human-in-the-loop approval, no new infrastructure.

6. Aider: minimal, git-native pair programming

Aider is the veteran of this list: Apache-2.0, Python, terminal-based AI pair programming that builds a repo map, applies edits as diffs, and commits each change with a generated message. It works with Claude, GPT, DeepSeek, Gemini, or local models. It is deliberately not autonomous (you drive every step), and it remains in 0.x versioning (latest release v0.86.0), so expect occasional CLI flag changes (github.com/Aider-AI/aider).

Pick it when: you want tight, git-disciplined interactive editing rather than an agent that runs unattended.

7. mini-SWE-agent: the research baseline that ships

Princeton and Stanford's SWE-agent pioneered automated GitHub-issue solving; its successor, mini-SWE-agent, compresses the agent to roughly 100 lines while scoring above 74% on SWE-bench Verified, MIT-licensed and used by Meta, NVIDIA, and IBM among others for evaluation pipelines (mini-swe-agent.com). It is the leanest way to run "take this issue, fix it" autonomy in CI, but it ships no UI, no workspace, and no review surface.

Pick it when: you want a scriptable, auditable autonomous loop for batch issue-fixing or benchmarking, and you will build the surrounding workflow yourself.

How should you choose?

• OpenHands if you want the closest thing to hosted Devin on your own infrastructure.
• Waynode if you want a durable workspace with review-first Git and mobile access (/guides/self-host-coding-agent-docker).
• OpenCode or Cline (editor) or Aider (terminal, git-strict) as an interactive daily driver.
• Goose if you want a general agent under open governance.
• mini-SWE-agent for headless automation in CI.

Every option here is free software; the real cost is model tokens plus your own operations time. Hosted Devin trades that operational load for quota-based consumption billing and a closed platform: a reasonable trade for some teams, and the one this whole category exists to make optional.

FAQ

What is the best open-source alternative to Devin in 2026?

OpenHands is the most direct substitute: an MIT-core autonomous coding agent with a web UI, self-hosted via Docker, able to run multiple agent engines. Which tool is "best" depends on whether you need autonomy (OpenHands, mini-SWE-agent), a persistent workspace (Waynode), or interactive pairing (OpenCode, Cline, Aider).

Is there a fully free, self-hosted Devin?

Yes, in the sense that OpenHands (MIT core), Waynode (MIT), and mini-SWE-agent (MIT) are free to self-host without license fees. You still pay for LLM API tokens unless you run local models, and OpenHands' Kubernetes "Cloud self-hosted" distribution specifically uses a 30-day-per-year trial license rather than MIT.

Is Waynode a Devin clone?

No. Waynode is a self-hosted workspace where an agent (pi, with pi-codex-goal for autonomous goals) works inside a real cloned Git repository, with diffs, branches, and push beside the conversation, persistent across sessions and usable from a phone. It optimizes for review and continuity rather than fire-and-forget autonomy.

How much does Devin cost compared to open-source options?

As of the April 2026 restructure, Devin's plans are Free, Pro $20/mo, Max $200/mo, Teams $80/mo plus $40/mo per developer seat, and custom Enterprise; paid plans include auto-refreshing usage quotas with overages billed at API pricing (devin.ai/pricing). Open-source tools have no license cost; you pay model providers directly, plus hosting if you run a server-based option like OpenHands or Waynode (Waynode Cloud starts at $39/month if you prefer managed hosting).

Can these agents run with local models?

Mostly yes. OpenCode, Goose, Cline, Aider, and OpenHands all support local models (typically via Ollama or an OpenAI-compatible endpoint), which removes token costs entirely at the price of lower model capability. Self-hosted Waynode is bring-your-own-key, so it uses whatever model endpoints you configure.
