I tested the top Factory AI alternatives: My honest review for 2025

You can’t scroll through tech news these days without hearing about AI software development agents. Tools like Factory AI are making huge waves, promising to automate the whole engineering lifecycle. It sounds like a dream, right? An AI teammate that can plan, code, and squash bugs for you.

But when you start digging into what people are actually saying, a different story comes out.

The vision is incredible, but for a lot of teams, the reality is still pretty messy. That’s exactly what sent me on a mission to find the best Factory AI alternatives available right now.

This article is the result of that deep dive. I’m breaking down the top five alternatives I’ve personally tested. We’ll look at everything from full-on AI developers to specialized knowledge tools, helping you find the right fit for your team without getting stuck with something that’s all hype.

What is Factory AI and why look for alternatives?

So, what’s the deal with Factory AI? They call it an "agentic development environment." The big idea is that instead of just getting a code autocompleter, you get a crew of specialized AI agents, or "Droids," to handle different jobs. There’s a Droid for research, one for coding, another for product planning, you get the picture. It plugs into your tools like GitHub, Slack, and Jira, and tries to understand your entire codebase to make changes.

On paper, it sounds amazing. The problem is, early adopters are hitting some snags. A lot of users are saying the Droids burn through tokens like crazy, and you often have to keep re-prompting and holding their hand to get the code right. Some people have even had trouble with basic features. The ambition is definitely there, but it feels like a tool that’s still working out the kinks. That’s why checking out more mature or focused alternatives is a good call right now.

What I looked for in the best Factory AI alternatives

This isn’t just some random list I copied from a marketing page. I judged these tools based on what I think actually matters when you’re trying to bring an AI agent into your team’s workflow.

• Does it actually work? I wanted to know how well it does its main job. Whether it’s writing code, finding an answer in your docs, or fixing a bug, it needs to be reliable.

• How easy is it to get started? How quickly can you get it up and running? I prioritized tools that don’t demand a week of a developer’s time and three sales calls just to see if they’re a good fit.

• Does it fit with how we already work? A great AI agent should feel like a natural part of your workflow, not another separate platform you have to juggle.

• Is the pricing clear and predictable? I’m not a fan of volatile, consumption-based pricing that can leave you with a shocking bill at the end of the month. I much prefer transparent, subscription models.

• What is it really best for? No tool is perfect for every single thing. I focused on figuring out the one thing each alternative is genuinely great at, whether it’s a general-purpose tool or a specialist.

The 5 best Factory AI alternatives in 2025

Alright, let’s get into the nitty-gritty. Each of these tools has a unique angle on AI-assisted development, and the best one for you really hinges on the problem you’re trying to solve.

1. eesel AI

Instead of trying to build a whole AI developer from scratch, eesel AI focuses on fixing one of the most painful parts of any engineering workflow: getting quick, correct answers from your internal docs. Think of it as the perfect replacement for Factory AI’s "Knowledge Droid," but designed as a practical, easy-to-use tool that provides value almost immediately. It’s for teams who are just plain tired of digging through messy docs and want a single source of truth.

Why it’s a great alternative:

• You can actually set it up yourself, in minutes. Forget about complicated onboarding. You can connect your knowledge sources to eesel AI and have a powerful internal chat assistant up and running in a few minutes. It’s completely self-serve, which means you don’t have to talk to a salesperson just to try it out.

• It brings all your knowledge together. This is its superpower. It connects to over 100 sources, including developer favorites like Confluence, Google Docs, and even old support tickets. It pulls everything into one place to give your team a reliable spot to ask questions.

• Business Plan: $639 per month (billed annually), includes up to 3,000 interactions, training on past tickets, and AI actions.

• Custom Plan: For larger teams who need unlimited interactions.

2. Devin AI

Devin is the tool that most closely mirrors Factory AI’s big vision of a fully autonomous AI software engineer. It’s designed to take a high-level prompt, like "build me a personal website," and manage the entire project from planning to deployment.

Why it’s a great alternative:

If you’re truly looking for a "fire and forget" agent to handle complex, end-to-end coding tasks, Devin is the most impressive option out there. The demos are wild, showing it planning its work, using common dev tools, and even fixing its own mistakes.

Pros & Cons:

• Pros: Seems to have a very high level of autonomy, can manage complex multi-step jobs, and has strong benchmark performance.

• Cons: It’s still in a limited early access beta, so you have to apply and wait. The pricing is also usage-based, which can be unpredictable, and it might be overkill if all you need is a bit of coding help.

Pricing:

Devin AI uses a consumption-based model with "Agent Compute Units" (ACUs).

• Core Plan: Pay-as-you-go starting at $20, with ACUs priced at $2.25 each.

• Team Plan: $500 per month, which includes 250 ACUs (comes out to $2.00 per ACU).

• Enterprise Plan: Custom pricing for bigger needs.

3. Augment Code

Augment Code is another direct Factory AI competitor, but it’s tailored specifically for large enterprise environments. It’s designed to be an AI coding partner that gets the security, compliance, and workflow needs of big companies.

Why it’s a great alternative:

If your main concerns are security and generating clean, maintainable code that fits your company’s standards, Augment is built for you. It puts a lot of effort into its context engine to really understand your entire codebase.

Pros & Cons:

• Pros: Strong enterprise focus, aims for high-quality and secure code, and users say it has a deep understanding of their codebase.

• Cons: Like a lot of enterprise software, you can’t just sign up and go; you have to talk to their sales team. Some users have also mentioned they wish it offered more choice in the underlying AI models.

Pricing:

Augment Code’s pricing is based on the number of "user messages" per month.

• Indie Plan: $20 per month for 125 messages.

• Developer Plan: $50 per month for 600 messages.

• Pro Plan: $100 per month for 1,500 messages.

• Max Plan: $250 per month for 4,500 messages.

• Enterprise Plan: Custom pricing and message limits.

4. GitHub Copilot Workspace

Instead of being a whole separate platform, GitHub Copilot Workspace builds agent-like features directly into the place where developers already spend most of their time. It’s less of a standalone "droid" and more like a powerful upgrade to the Copilot assistant you probably already use.

Why it’s a great alternative:

For any team that runs on GitHub, this is the easiest path forward. There’s no new tool to learn or set up. The AI is baked right into your pull requests and issues, which makes it feel incredibly natural to use.

Pros & Cons:

• Pros: Perfect integration with GitHub, builds on the familiar Copilot experience, and is very intuitive for existing users.

• Cons: It’s not platform-agnostic, so it’s not much help if your team isn’t all-in on GitHub. It might also be less capable for tasks outside the core coding and review cycle.

Pricing:

Copilot Workspace features are included with GitHub Copilot subscriptions.

• Free Plan: Includes a limited number of completions and chat requests.

• Pro Plan: $10 per month for individuals, with unlimited completions and more advanced models.

• Business Plan: $19 per user per month.

5. Cursor

Cursor takes a totally different path by creating an AI-native code editor from the ground up. It’s a fork of VSCode that’s been re-engineered for AI-assisted development. This one is for developers who want AI to be a core part of their IDE, not just a plugin.

Why it’s a great alternative:

If you’re constantly flipping between your editor and a separate ChatGPT window, Cursor merges those two worlds into one smooth experience. It gives you codebase-aware chat, code generation, and debugging inside a familiar environment.

This video provides an overview of an AI tool that serves as a strong competitor to Cursor for building applications quickly.

Pros & Cons:

• Pros: Fantastic AI integration in a familiar VSCode-style interface, and the free tier is surprisingly generous.

• Cons: It does require you to switch to a different code editor, which can be a tough sell for some dev teams with long-established workflows.

Pricing:

Cursor has plans for individuals and teams.

• Hobby Plan: Free with limited use of the Agent and Tab completion features.

• Pro Plan: $20 per month for unlimited Tab completions and higher Agent limits.

• Teams Plan: $40 per user per month, which adds centralized billing and admin features.

How to choose the right Factory AI alternative for your team

The right tool really boils down to the job you need it to do. Here’s a quick way to think about it.

Figure out what problem you’re actually solving

First, be honest about what you’re trying to fix. Are you hoping to automate massive, complex coding projects from a single sentence? Or are you just trying to stop your team from wasting 30 minutes a day looking for that one API doc in Confluence? The first goal might lead you to something like Devin, while the second is a problem that a tool like eesel AI is built to solve.

Think about your team’s habits

The best tools are the ones that cause the least amount of friction. If your team practically lives in GitHub, Copilot Workspace is a no-brainer. If your biggest headache is knowledge scattered across a dozen different apps, you need a tool that brings it all together without making everyone change how they work. That’s where a solution like eesel AI really helps, by connecting to your existing tools and bringing answers to you.

How much setup time do you have?

Do you have the time and people for sales demos, custom onboarding, and a long setup? Or do you need something you can try out this afternoon? Tools like eesel AI and Cursor are built for you to sign up on your own, letting you get started right away and see if it works for you in minutes.

Watch out for the pricing model

Be careful with consumption-based pricing if your usage is likely to be high or all over the place. A flat monthly fee gives you a predictable budget and lets your team use the tool without constantly worrying about how much each question is costing.

Moving from hype to practical Factory AI alternatives

The world of AI agents is moving at lightning speed, but it’s important to look past the hype. While all-in-one AI developers like Factory AI and Devin are giving us a cool glimpse of the future, the best Factory AI alternatives today are often the ones that solve one specific problem really, really well.

Specialized tools are usually more practical and can deliver a return on your investment way faster. For a task as critical as managing and accessing internal knowledge, a purpose-built platform is always going to be more efficient and reliable than a general coding agent that treats knowledge as an afterthought.

If your team is struggling to find answers in a sea of documentation spread across Confluence, Google Docs, and Slack, give eesel AI a try. You can connect your sources and set up a knowledge assistant for free in under five minutes to see the difference for yourself.
