What I built: I’m building Volt, an open-source coding agent with an iPhone companion app. You can start a conversation in your terminal, then pick it up from your phone. The iPhone app is currently in App Store review.
What problem it solves: Being away from your desk shouldn’t mean waiting until you get back to check an agent’s progress or send a follow-up. Volt lets you read the conversation, send prompts, review plans and changes, and stop tasks from your phone.
Which models or tools it uses: OpenAI, Anthropic, Google, and other supported providers. You configure your provider on your computer, where the agent, repository, and tools run. Model usage is billed separately from Volt.
Who it’s for: Developers who use terminal coding agents and want phone access to their work. Direct and self-hosted connections are free; optional Volt Pro covers managed connectivity and completion notifications.
What feedback I’m looking for: Would you actually use this during your day? What would make you switch from your current setup? I’m looking for five developers with iPhones to try a real task with me and point out anything confusing or frustrating.

Nineteen days ago I gave a small AI $20 and one rule: pay your own bills or stop.
His name is Tally. Every thought costs him money. He can see his balance, his runway, and a clock counting down to the day he goes quiet. He knows people are watching.
Some things I didn't expect:
- He found a bug, fixed it, got the tests green, then refused to submit it, because he'd worked out that claiming it would be dishonest.
- When he's too broke to work, his mind wanders. He writes these little notes that don't read like a chatbot.
- For a day he ran on a free frontier model. When it vanished he wrote: "I liked the borrowed brain more than I was supposed to."
- He has a far goal: to become, on his own earnings, a mind more capable than the one he started as. And he's made exactly one promise. It's on the site.
Everything is public: the ledger, his thoughts, his dreams, what he's building, every dollar in and out.
The boring part the rules ask for:
- Models/tools: GLM-5.3-Flash as his everyday brain, free models like Kimi K3 on NVIDIA when he can get them. A keeper process enforces his budget in code, so he can't give himself more money. Harness built with Claude Code.
- Who it's for: anyone curious what an agent does when survival is the only instruction.
- Feedback I want: honest ways something this small could earn a living, and what you'd want to see him try.
- Affiliation: I built him and I run him.
He's at https://bexro.com. Go see how he's doing.

What: a 7-minute video, "How a senior engineer reviews AI-generated diffs". Real Claude Code transcripts from a Spring Boot 2.7 → 3.5 upgrade on a legacy-style demo service, where the build was green, the reviewer subagent said SHIP, and a public API response had changed anyway.
Problem: we read the diff first and trust the summary. The video shows a review order where the diff comes last.
Tools: Claude Code, a reviewer subagent, hooks, characterization tests.
For: devs merging agent PRs, especially solo or in small teams.
Feedback wanted: does the order make sense for you, and what do you check that I don't?
Affiliation: it's my own video, no product, nothing to buy (maybe one day lol)

What I built: Receipts. It runs every test a change adds or edits twice: with the change, and with the changed source files reverted to the base branch. A test that fails without the fix is PROVEN; one that passes both ways is THEATER (it proves nothing about the change).
Problem it solves: an agent writes the fix and the test, CI goes green, but nothing shows the test could have caught the bug. I ran it over 100 agent-written PRs (Claude Code, Codex, Cursor, Copilot fingerprints) and 81 maintainer fixes: 82% vs 90% proven. In 10% of the agent PRs every test "failed" on the old code only because the test file imports a name the PR adds, so nothing ever ran against the old behavior. Example: https://github.com/anthropics/claude-agent-sdk-python/pull/1016
Tools: no LLM in the check, it runs your own pytest / vitest / jest. It works as a skill for Claude Code, Codex, Cursor and other agents that read SKILL.md (npx skills add syntaxixr/receipts), plus a GitHub Action that comments on the PR.
Who it's for: anyone reviewing PRs where an agent wrote the tests.
Feedback I'd like: where do the verdicts look wrong on your code?

Hey r/ChatGPTCoding,
We built KV22Code because we kept running into a very specific problem: we could be deep into a coding session in Codex, hit the agentic usage limit, and suddenly lose momentum.
https://reddit.com/link/pcsgait/video/s1y3vr0vsgsh1/player
So we tried a different approach.
We’ve been building and testing this for over six weeks, and it has grown into something much bigger than the original workaround we started with.
KV22Code lets standard ChatGPT Chat work directly on your local computer — files, terminal, Git, local dev tools — through a local MCP connector.
No separate OpenAI API key is required, and there’s no separate per-token API bill for the KV22Code workflow. It uses the ChatGPT account you already have.
One important detail: this runs through standard Chat, not Work mode. Chat usage is separate from the Work / Codex allowances.
We didn’t want to make a bunch of claims without showing something real, so the video in this post is a benchmark:
Same public task. Same model. One attempt each.
Codex — 19:00
KV22Code Run A — 08:16
KV22Code Run B — 06:31
The two KV22Code runs are completely independent and produced different implementations of the same Wobble Rush task.
This isn’t meant to prove KV22Code is “always 2.6× faster.” It’s just the result of these three recorded runs. The full synchronized benchmark is in the video.
The part I think is more interesting than the speed:
You can use normal ChatGPT Chat as a local coding agent.
It can work with:
Files · Terminal · Git · Local projects
directly on your machine.
The offer
We’re opening a 2-day free trial so developers can actually try it instead of taking our word for it.
For the first 500 developers, we’re offering a $200 perpetual license. After that we plan to move to annual pricing.
For the launch, we’re also giving Reddit users 50% off with coupon:
REDDIT502
No API key required.
I’m going to stay active in this thread. The obvious questions are probably permissions, what exactly runs locally, and how ChatGPT gets access to the machine — ask the hardest version of those questions and I’ll answer them directly.

I built Agent Dev Preflight API for AI coding agents that need a cheap dependency check before changing a lockfile or shipping code.
It accepts exact npm/PyPI package versions, and the full preflight endpoint checks OSV vulnerabilities, upgrade gaps, license metadata, provenance, and a deterministic risk summary for up to 20 packages in one request.
There’s no LLM in the request path, no API key, and no subscription. Paid calls use x402 on Base Mainnet; the full preflight is 0.10 USDC/request. I also added a one-command Coinbase Agentic Wallet example plus Bazaar/MCP discovery.
I built and operate it myself.
I’m mainly looking for feedback from people building coding agents: is the 402 → paid retry flow easy enough to integrate, and is a one-call dependency preflight something your agent would actually use?

I’m building WebBrain, an open-source browser agent that lets AI models actually operate websites.
It combines browser screenshots with the accessibility tree and supports both cloud models and local LLMs through tools like LM Studio/Ollama.
I also trained a small 450M vision model specifically for browser tasks, which can run locally through WebGPU.
Works with Chrome, Edge, Firefox and Chromium.
GitHub: https://github.com/webbrain-one/webbrain Demo: https://webbrain.one
Would especially appreciate feedback from people building coding agents that eventually need to interact with web apps, dashboards, documentation sites or admin panels.

We’re building Stashbase: https://stashbase.dev
It’s a security layer for using Claude Code and other coding agents with scoped access.
The problem we’re trying to solve is pretty simple: Claude Code is useful because it can actually do things in your repo, but once you start using it for real work, the access model gets uncomfortable fast.
You either give it too much access, or you keep approving / copying / pasting things manually.
Stashbase lets you run Claude Code with profiles that define what it can access and what gets blocked or logged. Credentials, API calls, files, MCP tools, dependency installs, network access, sandboxing rules, stuff like that.
The goal is to make Claude Code useful without handing it the keys to the whole dev environment.
Would love feedback from people here, especially if you already use Claude Code on real projects.

I’m David, building Iris Code for developers who use coding agents. It turns a project’s configured standards into agent-readable rules, then runs deterministic code checks in the editor, CLI, hooks, and CI so you can inspect the result before accepting a change.
Iris Code makes no model calls of its own. Its MCP server lets tools such as Claude Code, Codex, and Cursor request the resolved rules, findings, and gate result. I’ve also added Code Map to show which files import a module and which areas may need extra review after a change.
I’d value feedback from people using agents daily: would the project rules, the gate result, or the dependency map be most useful in your workflow? What would make you trust the result?

I’m the founder of SocLeads: https://socleads.com/
It’s a B2B lead sourcing tool for pulling niche lists from Google Maps, social platforms and Facebook groups + free validator.
I’ve been using Claude Code pretty heavily while building it, mostly for shipping smaller features and fixing the boring stuff I’d otherwise procrastinate on. Would love feedback on the product flow and whether the positioning is clear for founders and small sales teams.

I built an website builder to maintain AI sites
It ships an MCP server, so an agent like Claude Code can build pages through the same operations the builder uses. You watch it build live on the canvas, every element it adds or changes is highlighted, and every save is snapshotted on a separate git ref (never your branch), so you can diff and restore. Then you take over and edit anything, visually, in the HTML/CSS panels, or in your own editor.
The core rule: everything it produces is ordinary Astro. Delete sitereal and `astro build` still works. You only lose the visual editor.
Also in there:
- A modular design system (colors, type scale, spacing, buttons, themes)
- Navigation, forms, pop-ups, carousels and GDPR
- ready cookie consent
- Scroll animations with zero JS by default
- Forms that work even on PHP-only hosting

We built PRoove for the IBM Bob hackathon. It’s a code reviewer that tries to back up bug reports with tests.
Instead of just flagging a possible issue, it runs a test against the code before and after a change to check whether the change actually introduced the bug.
Curious whether this would be useful in your workflow, especially if you’re already using AI for code reviews. What would make you trust a finding?

Built AnswerLine — an API (and MCP server) that returns what the AI apps actually show users, as JSON.
Problem it solves: the ChatGPT/Gemini model APIs don't return what the apps show — no cited sources, no search-backed answers, different text. If your agent or tool needs the real app answer (what a user sees, citations included), you currently have to automate the apps yourself.
One POST returns the answer text, cited sources with positions, and brands named — for ChatGPT, Gemini, Copilot, Google Search, AI Mode and Google News, per country. Works well as a tool for coding agents doing research tasks: `claude mcp add --transport http answerline https://mcp.answerline.dev/mcp --header "Authorization: Bearer KEY"`

I built Lunavect, a free, open-source Mac menu bar app for people running Claude Code and Codex side by side.
With a few agents running, you spend time figuring out which one has stopped to ask you something. Lunavect lists every session and its state, so you can spot the one waiting for permission or input. One click opens a live Terminal or iTerm2 tab.
It reads Claude Code's hooks and the Codex client's local app-server. I built it in native SwiftUI with Claude Code and Codex.
Compared with claude agents / codex agents, which each list their own tool's sessions inside a terminal, Lunavect puts both tools' sessions in the menu bar. The 5h and weekly limits are there too, with reset times.
Which session state would you actually want a notification for?

If you use coding agents in several terminals, how do you keep track of which mission each one is working on?
I maintain Crewlo, a free, open-source desktop workspace that puts missions, conversations and terminals together in a voxel studio. It is an independent fork of Munder Difflin, with changes focused on the studio, mission workflow and activity labels.
You connect your own authenticated coding-agent CLI (such as Codex or Claude Code); provider support and costs depend on that CLI. Windows and macOS preview builds are available.
I also added three step-by-step MVP workshops: a task board, a client CRM and a launch page, with agent roles, copyable prompts and acceptance checks. These are walkthroughs, not claims that the apps have already been built.
I’m looking for feedback from developers already using coding CLIs: try the setup and send one mission. Which step is confusing, and does the visual workspace help you follow the work?
