Devin and its alternatives at a glance
| Agent | Best for | Starts at | Better than Devin at | Checked |
|---|---|---|---|---|
| Devin | Engineering teams offloading well-scoped migration tasks without adding headcount | Free, then $20/month source | 2 September 2026 | |
| Factory | Engineering organizations that want AI agents handling more of the SDLC than code generation alone (triage, testing, release and documentation) and are willing to pay enterprise pricing for deployment flexibility and compliance controls. | From $20/month source | Model choice, Bring your own key | 2 September 2026 |
| OpenCode | Developers who want a genuinely free, fully open-source coding agent that works with any model provider, including their own local Ollama models, without being locked into one vendor's terminal tool. | Free, then $10/month source | Model choice, Self-hosted | 21 October 2026 |
| Muse Code | Cost-sensitive teams willing to trade code privacy for Contributor tier's roughly 12x cheaper input and 21x cheaper output, or anyone with a large multi-part refactor that benefits from several sub-agents working in parallel isolated worktrees. | From $5/month source | Opt out of training | 20 September 2026 |
| Aider | Developers who want free, model-agnostic AI pair programming in their terminal | Free source | Model choice, Self-hosted | 30 September 2026 |

Shortlist
Closest alternatives to Devin
The ones people open most here come first, then the closest matches. How we rank
- 01
WTAgent
Open-source CLI that drives your existing ChatGPT, Claude or DeepSeek web session as a local coding agent.
From FreeWhy it's on this listModel choice · YesYou pick the provider on the command line from a published list, and two of them inherit whatever model your browser profile has selected.Source ↗
Where it improves on Devin
Trade-offs against Devin
- −Runs autonomously · PartlyReads, writes and ordinary project commands run automatically, but a human must sign in to the web AI first and approve anything sensitive or destructive.Source ↗
- −Agent permissions · PartlyA local policy engine grades every tool call by risk: reads, writes and builds inside the project run unattended, sensitive or destructive calls need approval.Source ↗
- −Open models · PartlyProviders include DeepSeek, Kimi and GLM, whose weights are published openly, but WTAgent drives their hosted web chat rather than running any weights locally.Source ↗
- 02
Factory
Droid coding agents that run in the desktop app, CLI, IDEs, CI and Factory-managed cloud computers.
From $20/monthWhy it's on this listThe enterprise-grade delegation alternative for teams that want Devin's full SDLC scope with specialized roles and stronger deployment controls. Factory coordinates specialized Droids across the full software development lifecycle rather than running one general-purpose agent, and publishes a self-serve $20/month Pro CLI tier alongside Plus ($100/mo), Max ($200/mo), and custom Business/Enterprise tiers that add SSO, on-premise and air-gapped deployment — Devin's equivalent of VPC deployment sits behind a custom-priced Enterprise plan. The trade is that there is no free tier or trial, so evaluation means committing budget up front, and Factory's public track record on autonomous ticket-to-PR resolution is shorter than Devin's, so teams with strict delegation success-rate SLAs should size a pilot before scaling.
Where it improves on Devin
- +Model choice · YesYou pick the model per session, per subagent and per exec run with -m/--model, or add custom endpoints.Source ↗
- +Bring your own key · YesBYOK covers your own OpenAI/Anthropic keys, OpenAI-compatible gateways, local models and AWS Bedrock; keys stay on your machine.Source ↗
- +Certifications · YesSOC 2 Type II, ISO 27001 and ISO 42001, with reports and sub-processor lists in the Trust Center.Source ↗
Trade-offs against Devin
- −Free tier · NoEvery priced plan on the page is paid: the ladder runs 01 Pro at $20/mo to 06 Enterprise, with no $0 tier and no trial named anywhere on it, so the cheapest way in is a self-serve $20 monthly subscription. Free usage appears only inside paid plans - a BYOK allowance and a free switch to Droid Core after a rate limit.Source ↗
- −MCP server · PartlyDroid is an MCP client over stdio/http/sse and can be driven by another program over JSON-RPC or ACP, but no Factory-hosted MCP server is documented.Source ↗
- −Pooled budget · PartlyTeams seats each keep their own Pro rate limits; Business and Enterprise usage is shared across the workspace.Source ↗
- 03
OpenCode
Open source AI coding agent for the terminal, desktop, IDE and browser, with any LLM provider.
From FreeWhy it's on this listModel choice · YesYou pick the model per session or per agent in provider/model form; the vendor's own gateway is explicitly optional rather than a default lock-in.Source ↗
Where it improves on Devin
- +Self-hosted · YesThe agent runs on your own machine or server with no vendor backend in the path, and enterprises can point it at an internal AI gateway only.Source ↗
- +Open source · YesSource is public under the MIT licence and the project takes outside issues and pull requests, so the agent itself can be forked and modified.Source ↗
Trade-offs against Devin
- −Whole-codebase work · PartlyBuilt for multi-step work across a repository through subagents and LSP loading, but the docs describe no repository-wide index or migration guarantee, so scale rests on agent orchestration.Source ↗
- −MCP server · PartlyMCP runs one way here: OpenCode consumes local and remote MCP servers, and no MCP server of its own is documented, though its HTTP API lets other software drive it.Source ↗
- −Seat model · PartlyThe gateway charges no seat fee at any team size, so seats only appear in the unpriced enterprise agreement, which is quoted rather than published.Source ↗
- 04
Muse Code
Meta's terminal and CI coding agent, built on the Muse Spark model.
From $5/monthWhy it's on this listOpt out of training · YesStandard-tier models are contractually excluded from training, and the discounted contributor models that do train on your content are opt-in by model id and can be left behind by upgrading.Source ↗
Trade-offs against Devin
- −Reviews code · PartlyReview happens inside its own runs — background reviewer and verification agents check the work — rather than as a review of a diff someone else wrote in a pull request.Source ↗
- −Whole-codebase work · PartlyIt splits a large job across parallel subagents with optional Git worktree isolation, which fits a repository-wide migration, but the vendor documents no repository indexing and caps a tree at eight concurrent agents by default.Source ↗
- −Claude · NoThe plan table and the model-ID pricing enumerate only Muse Spark; no third-party model is offered inside Muse Code.Source ↗
- 05
Aider
Open-source terminal AI pair programmer that edits files in your local git repo and commits the changes.
From FreeWhy it's on this listModel choice · YesYou choose the model per session with --model and can switch mid-chat with /model, and the vendor claims connectivity to almost any LLM rather than a fixed engine.Source ↗
Where it improves on Devin
- +Self-hosted · YesAider is installed on your own machine with pip, uv, pipx or Docker and edits files in your local repo, so there is no vendor runtime to depend on.Source ↗
- +Open source · YesThe company behind the tool states the source is on GitHub under a permissive Apache 2.0 licence, and documents running and modifying it from source.Source ↗
Trade-offs against Devin
- −Writes tests · PartlyThe vendor advertises asking it for test cases, but every documented testing feature is about running your existing test command and repairing failures, not a dedicated test-generation workflow.Source ↗
- −Reviews code · PartlyReview works by piping a diff into the chat yourself with /run git diff or --read and then asking in ask mode; there is no pull-request integration that reviews someone else's diff automatically.Source ↗
- −Whole-codebase work · PartlyA ranked map of the whole git repo gives it repository-wide context, but the vendor warns performance is not optimised for very large monorepos and only one repo can be open at a time.Source ↗
- 06
Junie
JetBrains coding agent for the terminal, JetBrains IDEs and CI, running on hosted or your own model keys.
From FreeWhy it's on this listModel choice · YesYou choose, not the vendor: four provider classes are supported and a flag forces a specific one, though leaving the default lets JetBrains pick on price-quality grounds.Source ↗
Where it improves on Devin
- +Bring your own key · YesSix providers accept your own key, billing bypasses JetBrains entirely, and a supplied key wins over the subscription when the same model is reachable both ways.Source ↗
- +Opt out of training · YesTraining on your code is off unless you switch it on, the exclusion is ticked on every tier including free, and the commitment is contractually extended to model subcontractors.Source ↗
Trade-offs against Devin
- −In a browser · PartlyThe web app is a companion view onto a CLI session still running on your own machine, not a standalone hosted agent, and the vendor lists a dozen features it cannot do.Source ↗
- −Open source · NoThe public repository carries installers, model profiles and a plugin rather than agent source, and its licence section reserves all rights and points at proprietary service terms.Source ↗
- −MCP server · PartlyMCP runs one way only: Junie consumes external MCP servers as a client. Another program reaches it through ACP instead, and no MCP server exposing Junie is documented.Source ↗
- 07
Kilo Code
Open source AI coding agent for VS Code, JetBrains, CLI and cloud, with 500+ models at provider rates.
From FreeWhy it's on this listModel choice · YesYou pick the model; Auto Model routing is optional and never silently substitutes.Source ↗
Where it improves on Devin
Trade-offs against Devin
- −Agent permissions · PartlyAuto-approve exists, but the OS-level sandbox that bounds it is experimental and Linux/macOS only.Source ↗
- −API access · PartlyCloud Agent sessions can be launched by HTTP webhook and usage data has documented OpenAPI endpoints; no public API for driving the agent itself is documented.Source ↗
- −Admin controls · PartlyTeams gets data-privacy controls on models and providers; allowlists, RBAC and policy enforcement are Enterprise.Source ↗
- 08
Gemini Code Assist
Google's per-seat AI coding assistant and agent for IDEs, the terminal and GitHub pull requests.
From $22.80/monthWhy it's on this listAudit log · YesCloud Audit Logs under serviceName cloudaicompanion.googleapis.com, split into Admin Activity and Data Access entries; code completion and generation calls are themselves audited.Source ↗
Where it improves on Devin
- +Single sign-on · YesIdentity comes from Cloud Identity or Google Workspace, or an external IdP federated into them, and Google's own guidance is to enable single sign-on. Neither SAML nor OIDC is named on the page.Source ↗
- +Opt out of training · YesNothing to opt out of: no training on prompts or responses by default. Preview and Trusted Tester data sharing is opt-in and used for product improvement, not training.Source ↗
Trade-offs against Devin
- −Multi-agent · NoThe vendor describes agent mode as one collaborative agent working with the developer; no orchestration of several agents on one task is documented.Source ↗
- −Claude · NoGoogle's own Gemini models only; no third-party model is offered on any edition.Source ↗
- −GPT · NoGoogle's own Gemini models only; no OpenAI model is offered on any edition.Source ↗
- 09
Cursor
Coding agent in a desktop editor, terminal CLI, cloud VMs and CI, priced per seat plus token usage.
From FreeWhy it's on this listThe direct answer to Devin's own "fast, interactive in-editor copilot" line: Cursor is an AI-first fork of VS Code where you pair with the agent in real time inside the editor, rather than assigning a ticket and waiting for a cloud session to finish. Pricing is flat monthly tiers ($20 Pro, $60 Pro+, $200 Ultra, $40/user Teams) rather than Devin's stacked subscription-plus-metered-credit model, though it gives up Devin's unattended, walk-away autonomy in exchange for that interactivity.
Where it improves on Devin
- +Model choice · YesYou pick the model per request, or hand selection to Auto/Cursor Router; each choice bills at that model's own rate.Source ↗
- +Bring your own key · YesYour own keys for OpenAI, Anthropic, Google, Azure OpenAI and AWS Bedrock; chat models only, Zero Data Retention does not apply, and Enterprise admins can disable BYOK.Source ↗
- +Opt out of training · YesPrivacy Mode is available on every plan, settable by the user or enforced by a team admin, and is on by default for Enterprise; it does not cover BYOK requests.Source ↗
Trade-offs against Devin
- −Open models · PartlyAll inference is hosted: the catalogue includes GLM 5.2 from Z.ai and Kimi K3 from Moonshot, but there is no path to point Cursor at open weights you run.Source ↗
- −Open source · NoThe Terms of Service forbid deriving or accessing the source; the /licenses page covers only third-party open source components used inside the IDE.Source ↗
- −MCP server · PartlyMCP is inbound only: Cursor is the client that connects to MCP servers. Another agent drives Cursor over ACP (agent acp) or the SDKs, not by querying an MCP endpoint Cursor exposes.Source ↗
What to watch for
- DevinIndependent real-world testing has found success rates around 15% on a 20-task sample, well below the roughly 45.8% Devin 2.0 reports on SWE-bench Verified, so performance varies significantly by task type and spec quality.
- FactoryNo free tier or trial — the cheapest plan is $20/month.
- OpenCodeThe web UI's server-URL-override feature and local HTTP server have a real, disclosed 2026 security history (two now-patched advisories), so running it on a shared or untrusted network needs care.
- Muse CodeThree observer agents (memory, skill, goal) run by default and add their own billed model calls on top of the main session, switchable in settings.json under runtime_capabilities.
- AiderUsage numbers like 44K GitHub stars, 6.8M installs, 15B tokens/week and the 88% 'Singularity' metric are self-reported on aider.chat; independent verification of these figures was not found.
- JunieCredit-based pricing shared across all JetBrains AI features makes the effective monthly cost of regular agentic use harder to predict than a flat subscription.
- Gemini Code AssistPrivate-repository customization is gated to the Enterprise tier, and agent mode is still in preview
- CursorNo first-class headless or CI mode. Cursor is an interactive editor with a CLI and background agents, not a scriptable terminal agent in the same mould as Claude Code or Codex CLI.
