GSD Pi is built around an execution loop that keeps AI-assisted engineering honest: discuss messy intent into explicit scope, plan durable slices with the right context, execute work in clean contexts and worktrees, verify behavior with evidence, and ship with clean commits and trustworthy handoffs. From the shell, users can start guided or quick coding sessions, break work into milestones, slices, and tasks, and let auto mode plan, implement, verify, and advance the work. It stores requirements, decisions, runtime notes, generated plans, summaries, and validation evidence. -
15
MiMo Code
Xiaomi Technology
MiMo Code is a terminal-native AI coding assistant designed to live inside the developer’s computer, understand the project more deeply over time, and improve as it works. It can read and write code, run commands, manage Git, and keep a persistent project context across sessions through a built-in memory system. Instead of relying on the model to remember on its own, MiMo Code uses project memory, conversation checkpoints, scratch notes, task progress, and SQLite FTS5 full-text search to preserve rules, architecture decisions, session state, and ongoing work. When context nears the limit, it reconstructs the working state from the latest checkpoint, memory, task progress, and recent messages so the agent can continue rather than start from scratch. Multiple agents support different workflows, build for full-permission development, plan for read-only analysis, and compose for specs-driven development. -

InstaLILY
InstaLILY
The InstaLILY Platform is the foundation under every Lily solution, built around the idea that the work changes, but the foundation does not. Lily builds software around the way a business actually works, using one shared platform for contracts, connectors, access, testing, deployment, identity, audit, observability, and runtime. Instead of starting every solution from zero, Lily starts with the workflows, systems, data, decisions, approvals, and judgment already inside the business, then builds the agents and automations the work needs, from quotes, schedules, approvals, follow-ups, routing, service tickets, inventory checks, contract terms, and customer updates to other high-friction workflows that off-the-shelf tools do not cover. It keeps every solution on the same standard: typed and versioned contracts, scoped permissions, explicit schemas, runnable examples, legible errors, observable behavior, tests, conformance gates, and upgrade-safe release paths. -
18
Keelen
Keelen
Keelen is an autonomous coding loop. It turns free-form requests into a prioritized roadmap, breaks roadmap items into dev-ready tasks with acceptance criteria, implements each task in an isolated single-use VM using your own Claude, Codex, GLM, or Kimi credentials, and ships the result as a merged pull request, or holds it for review if that is how you configure it. Every change passes five verification gates before merge: a red-first test proof, an independent adversarial review of the diff by a model that shares no context with the run that wrote it, the project's own test suite on a clean checkout, a CI-green requirement, and a review window before gated auto-merge. The loop may never weaken a check to reach green. Each iteration runs in a single-use, non-root VM that is destroyed when the run ends, with deny-by-default network egress. Per-run GitHub tokens are scoped to one repository. Keelen is not an IDE copilot and not a chat agent.Starting Price: $29/month -
19
Favur
Awesoft Solutions
Favur is an autonomous software-building system that takes a written statement of work and turns it into a complete, tested repository without a human steering the run. A team of agents plans, builds, reviews, tests, and ships the project on its own, while scoring its own work, catching mistakes, and steering itself back on track. Every run follows the same lifecycle, architecture, sprints, review, and tests, whether the task is small or a serious project. It first reads the ask, commits to an architecture, and records its decisions before code is written. Then it breaks the work into sprints and writes pseudocode before building. One agent writes the code, a separate reviewer checks the diff against the plan, and a tester proves the result. Agents can run on different models within the same job, allowing teams to mix models for boilerplate, judgment calls, supervision, and other roles. -
20
Peezy
p0
Peezy for Mac is a native coding agent designed to help developers build anything locally or in the cloud. It runs directly on macOS with a privacy-first approach and gives users full control over their development environment while keeping AI assistance close to the projects they are working on. For larger workloads, cloud coding lets users offload heavier tasks and scale when needed instead of relying entirely on local resources. Peezy can plan builds, read project graphs, install dependencies, compile modules, run tests, optimize assets, generate types, bundle projects, and finalize clean builds as part of its coding workflow. It remembers projects, context, and preferences over time, creating continuity across sessions rather than forcing developers to repeatedly re-establish what they are working on. Powerful slash commands help speed up common development actions, while Peezy Voice lets users talk to the agent and build by voice while keeping their hands on the keyboard. -
21
Phoenix.vu
iBoson Innovations Private Limited
Phoenix.vu is an AI coding agent built natively for Xcode — not a generic tool adapted to fit. Describe a change in plain English, and Phoenix.vu reads your actual project structure, writes the Swift code, runs the real Xcode build, and iterates through compiler errors until it compiles clean. It's especially strong at build-error and failing-test fixes, bounded refactors across multiple files, and generating tests for existing code. Every change comes back as a reviewable diff inside Xcode — nothing applies without approval, and there's no copy-pasting between a chat window and your editor. It remembers project context across sessions, so you're not re-explaining your codebase each time. Privacy-first: source code and project history stay local on your Mac; only the minimal context a task needs is sent for inference, and nothing is retained afterward. Pricing is pay-as-you-go credits from $10, no subscription required.Starting Price: $10 -
22
Reason

ML.ai
Pixis.ai
Ml.ai is an AI coding agent that goes where your code goes. Use it inside VS Code and Cursor, in its own desktop app with no IDE required, from the terminal, or as a PR Reviewer that checks every pull request. Every surface runs on the same engine, with the same settings and the same memory of your repo. Most coding agents send every step to the same expensive frontier model. Ml.ai hands each step to a focused agent and picks the most cost-efficient model that meets your quality bar, which typically cuts model spend by 30 to 45% on the same work. Explore reads and explains the codebase. Architect and Plan map the files, order of work and trade-offs. Only General can change code, and every edit or command waits for you to Allow or Deny it. The PR Reviewer summarizes each pull request, leaves line-level comments, and runs builds and tests before it recommends approve or request changes. It never merges on its own. Also included: reusable skills, background runs, MCP server support. -
27
OpsAgents AutoPilot
OpsAgents AI
OpsAgents AutoPilot turns your backlog into pull requests. It takes the next ticket off your board, reads your repository, writes the change on its own branch and opens one pull request per ticket for your team to review - then stops.
