AI Tools for Developers (2026)

12 tools tracked · 9 active · 3 dead or at risk · Updated August 3, 2026

A developer's AI stack now spans three layers: an in-editor assistant, one or more model APIs, and the platform where models and datasets live. Each layer has a different failure mode. Assistants get acquired, APIs deprecate model versions with short notice, and platforms change terms as they scale.

The most expensive dependency is rarely the assistant - it is the API. Hard-coding a specific model name into production is how teams end up doing an unplanned migration on a deprecation deadline.

Everything below is status-checked, including one shutdown and one acquisition in the assistant layer. Where a tool died, we link to what happened and where its users went.

Devin (Cognition)

🟢Active

Best-known autonomous coding agent

Cognition unveiled Devin in March 2024 as 'the first AI software engineer', capable of taking a Linear ticket and shipping a pull request end-to-end. Independent reviewers (notably Carl Brown's analysis) showed the launch demo was carefully edited and that real-world success rates were modest. Cognition kept iterating and acquired Windsurf in July 2025 to give Devin a real IDE surface. The company's valuation reached $4B+ in 2025 funding rounds.

Dead or At Risk

These have shut down, been abandoned, or been absorbed into another company. Check before you renew.

Windsurf

🟡Acquired / Merged

Acquired - plan for roadmap changes

Codeium rebranded its AI IDE as Windsurf in late 2024 and grew into one of the most-used Cursor alternatives. Google announced an unusual $2.4B licensing deal in July 2025 that took CEO Varun Mohan, co-founder Douglas Chen, and the core research team to DeepMind without buying the company. Two days later, Cognition (maker of Devin) acquired the remaining Windsurf product, IP, and employees for an undisclosed sum. Windsurf now operates as a Cognition brand.

MosaicML

🟡Acquired / Merged

Acquired - training platform folded into a data company

MosaicML built tools for training large language and diffusion models efficiently on commodity GPUs, releasing the MPT-7B and MPT-30B open-source models in 2023. Databricks acquired the company in July 2023 for roughly $1.3B, folding MosaicML's stack into the Databricks platform as the basis for what later became DBRX and the Mosaic AI training service. The standalone MosaicML brand was retired; the team and tech continue inside Databricks.

How to Choose

→Is the API versioned, with a published deprecation policy?
→Can you swap providers without rewriting your prompt layer?
→Does your code or data get retained for training by default?
→What is the real cost at production traffic, not at demo traffic?

Frequently Asked Questions

What AI tools should a developer use in 2026?

A capable in-editor assistant such as Copilot, Cursor, or Codeium; at least two model APIs so you are not single-sourced; and Hugging Face for open models and datasets.

Which developer AI tools have shut down or been acquired?

Kite shut down, Windsurf was acquired, and MosaicML was acquired and folded into a data platform. Each is listed with its verified status here.

How do I avoid lock-in to one model provider?

Keep prompts, tool definitions, and evaluation harnesses in your own codebase behind a thin provider interface, and run the same evaluation suite against a second provider regularly.
