From DeepReinforce, Ornith hands task writing, scaffolding and solution writing to the model itself, comes in three sizes from 9B to 397B, and ships under MIT with a 256K context and local deployment.

An open extension that plugs into the editor you already use and talks to whichever model you point it at: cloud, local, or a private deployment inside the company network, with the configuration written in a file you own.

Devin Desktop is Cognition's AI coding environment, renamed from Windsurf in 2026, where a board called Agent Command Center supervises local and cloud agents side by side.

Not a faster typist but a memory: it records what you did in editors, browsers and terminals, keeps it on the machine for nine months, and lets other AI tools borrow it through MCP.

A test writer and a pull request reviewer in one platform: Qodo reads a function, builds a suite that covers the awkward paths, then vets the change before it merges. Free for individuals.

One assistant in three shapes - plugin, IDE and command line - with a path from a designer's file to working code and a deploy step in the same place, free tier included.

One product with two entrances: an AI-native IDE where a solo agent can drive a project end to end, and a workbench for people who produce documents and data rather than code.

One sentence becomes three documents you sign off on, requirement conflicts get checked by automated reasoning, and property tests cover the edge cases unit tests miss.

Every task gets its own clean remote machine, the agent keeps working after you close the lid, and a phone, browser or terminal is enough to take over. Bring your own model and the platform costs nothing.

An open source desktop companion that sends several agents into their own branch worktrees, meters the context each one burns, and keeps the diff and the editor in the same window.

A community continuation of Roo Code that turns one agent into four fixed roles, shows every change as a diff before it lands, and throws a guard over dangerous commands during long unattended runs.

A single compiled Go binary replaces the old Node-based entry point, sharing one agent harness and one set of settings with the desktop app, running sub-agents in parallel inside an operating-system sandbox.

The network is off by default and writes stop at the working directory, with edits and commands passing an approval step; rewritten in Rust it is one static binary that also runs unattended in a pipeline.

One command puts an agent to work on the whole repository: it reads, edits, runs commands and opens a pull request, while the code stays local and no remote index is involved.

Devin Desktop, the renamed Windsurf, folds local and cloud agents into a single status board and lets third-party agents join through an open protocol.
