Morph Fast Apply
Morph
Morph FastApply is a specialized AI infrastructure tool designed to dramatically improve how AI coding agents edit and update source code. Instead of rewriting entire files or relying on fragile search-and-replace operations, FastApply merges AI-generated code changes directly into existing files using a semantic understanding of the code structure. It works by allowing an AI model to output only the relevant modifications to a file while marking unchanged sections with placeholders. The FastApply model then merges those changes server-side, reconstructing the complete updated file while preserving formatting, syntax, comments, and dependencies. This approach significantly reduces the number of tokens required and eliminates many of the errors caused by traditional diff-based or search-and-replace editing methods. It processes edits at speeds of over 10,500 tokens per second with approximately 98% accuracy.Starting Price: $20 per month -

CircuitHawk
BQR Reliability Engineering
Today’s electronic designs are becoming increasingly complex, making it harder to detect errors that generate high costs and hundreds of work hours. Detecting these errors in advance can be instrumental in preventing these damages. Unfortunately, in many cases, these errors are discovered only in the testing phase or at the customer’s site. BQR’s CircuitHawk is a powerful and unique (patent based) design error detection and stress analysis tool for electrical circuits. CircuitHawk detects design errors during the design phase, before layout and production. This way, no schematic, connectivity or stress errors are found in the qualification tests during final verification. CircuitHawk shortens design cycles and time to market, which in turn saves a lot of money and helps bolster corporate reputation. CircuitHawk is the only tool integrating design error detection with electrical stresses, thermal, MTBF and service life prediction at the schematic level, before PCB layout and production. -

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 -

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 -

Tonkotsu
Tonkotsu
Tonkotsu is a desktop application that lets developers manage a team of AI coding agents from a document-centric interface, enabling a structured plan, code, and verify workflow that scales software development by delegating multiple coding tasks in parallel while maintaining human oversight and control. From within a single doc, users set project direction and context, Tonkotsu analyzes codebases and drafts detailed plans, and then developers assign and manage dozens of autonomous tasks without micromanagement; once work is complete, teams review diffs, comment inline, and approve changes, with automatic build, lint, test, conflict resolution, and merges to streamline iteration, ensuring no commits are finalized without explicit approval. Built for professional developers on macOS and Windows, it supports planning across multiple repositories, symbol lookup for context continuity, task dependency specification to order work logically, and automatic verification to enhance accuracy. -

GSD Pi
Open GSD
GSD Pi is a local-first coding agent for planning, implementing, verifying, and tracking project work from the command line. It combines a terminal agent, project workflow tools, worktree-aware Git automation, local project memory, model routing, and optional UI integrations so a project can move from idea to reviewed implementation with less manual coordination. 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. -

CodeLazr
CodeLazr
CodeLazr is a web-based AI coding agent that edits your GitHub repos directly from the browser. No install, no cloning, no containers. Pick any OpenRouter model, including free ones, or bring your own API key. Every change is staged as a diff you review before it commits, auto-commits, or opens a pull request. CodeLazr is built to make cheap and free AI models reliable for real coding: automatic retries with a fallback chain of models, a second model that reviews each diff before commit, and detectors for the common ways weaker models fail. Includes built-in prompt templates for common tasks like fixing bugs, writing tests, refactoring, and writing docs. More than 1,400 test runs are published publicly on the CodeLazr stats page, failures included. Free plan with free models and no card required, Pro at $10 per month, or bring your own key to use it free forever.Starting Price: $10/month -

Reasonix
Reasonix
Reasonix is an open source coding agent designed for long autonomous sessions that remain readable, auditable, and reversible. One local engine powers four interfaces: terminal, desktop app, browser, and ACP-compatible editors, with sessions, permissions, skills, and MCP servers shared across them. Plan mode holds every write until the proposed steps are reviewed and approved, while reads, writes, and shell commands are separately gated and constrained by a workspace sandbox. Each turn creates a checkpoint outside Git, allowing users to rewind a long run without affecting commit history. MCP support over stdio, SSE, and streamable HTTP merges external tools into one registry, while Markdown skills and isolated subagents extend the agent without requiring a fork. Reasonix maps a codebase once and keeps that map throughout the session, letting users queue tasks, review diffs, and resume work without losing context.Starting Price: Free -
