coding agents struggle with large migrations.
slow, unreliable, costly. they need a lot of babysitting.
if you’re a platform/principal eng you’ve felt this pain 😅

so we gave them a new superpower

npx codemod ai 🎉

everything your AI coding agent needs for fast, reliable code migrations

free, open source, local-first, no login

and it gets better over time as models improve + community contributes to the registry

try it. break it. tell us what sucks

link + debarrel case study in replies 👇🏼

Despite all the great coding agents out there, @zapier turned to @codemod to make i18n basically invisible for their devs.

@codemod is becoming the Mission Control for coding agents with on-demand specialized agents, compiler-aware tech, semantic analysis, and code graphs that turn complex migrations into background workflows. It works with any coding agent and gives them a modern and secure foundation to do their best work.

check out the story👇🏼and ping me if you want a live demo. Happy to help with any codebase maintenance or remediation project.

New in Codemod jssg: deny-by-default security model! No file system, network, or subprocess access unless explicitly allowed in `codemod.yaml`

🚨 jssg codemods just got safer! 🔐

[Codemod @codemod]

We’re excited to share that jssg, our open-source, multi-language codemod toolkit and jscodeshift alternative, is now production-ready! Whether you're refactoring codebases, upgrading frameworks, or applying best practices across your org, jssg has you covered.

huge thanks to @nodejs for teaming up with us this past year to make codemods easier to build, publish, and run for all framework/SDK maintainers.

and excited to officially kick off our @openjsf partnership, bringing @codemod to more OSS projects under their umbrella and beyond.

if you’re a framework maintainer, DM me! I can spin up a codemod repo like nodejs/userland-migrations in 30mins so your community (or folks in @codemod) can ship migrations as you ship new releases!

[OpenJS Foundation @openjsf]

OpenJS 🤝 Codemod

Node.js migrations just got way easier. We're partnering with @codemod to help developers update apps faster, safer, and with less manual hassle.

If you're looking to adopt Next 15.5's `typedRoutes` feature, the good folks at @codemod have a script to automate adding the type annotations to all of your files!

[Mohebifar @mohebifar]

we made a codemod for the next 15.5 new typedRoutes feature. upgrade your code instantly with one command!

ast-grep fine tuning / RL should be part of every lab’s post training regime if they are serious about coding agents.

Would be helpful to create evals for.

[Alex Bit @alex__bit]

node.js codemods!

open-source fans: we’ve teamed up with amazing Node.js maintainers (Jacob Smith, @_August1_, and more) to launch Userland Migrations, a community-led effort to help Node.js devs adopt new features faster and easier.

Wanna learn how to build codemods and help millions of devs? check out https://t.co/3fxXDXfL9s or ping me to get involved.

[Mohab Sameh @mohab__sameh]

@MaxProgramming1 @nodejs @_August1_ @codemod Thanks for the contributions! 🙌🏼

[Alex Bit @alex__bit]

Big update just landed on https://t.co/50h1aRpX1S!

Smarter AI. Multi-file, multi-step workflows. More powerful codemods (supports both JS ast-grep and YAML rules).

Early adopters! DM me if you're down to try it out and share some honest feedback. 🙏🏼❤️🍻

[Herrington Darkholme @hd_nvim]

you can create ast-grep rule using @codemod studio and it is quite amazing

[Mohab Sameh @mohab__sameh]

@devwithalex @Shopify Love it, Alex! If you plan to open source them, I'd love to support you in publishing them on https://t.co/wG4WYI2qv3. This way, thousands of devs can easily discover and use them.

[Mohab Sameh @mohab__sameh]

@lubieowoce @jarredsumner second this. building codemods that turn LLM-hallucinated calls into the real bun apis is a perfect balance between keeping api stability and convenience. @jarredsumner if the Bun community wants to make it happen, we (https://t.co/4v9t4Zu5Sv) would love to support you.

[Mohab Sameh @mohab__sameh]

@mohritaroh Awesome article. Thanks for sharing your codemod lessons! We have a community of codemod champs; we’d love for you to join us and talk about all things codemods!

back in the days of big corp, we had live dashboards of code health + migration progress across 70+ eng teams.

total game-changer.

we could see legacy APIs dying.
we could feel momentum.
we could celebrate burndown.

now at @codemod, we’re building a better version for everyone else: Codemod Insights 👇

eng leaders can say “i wish i could track X across the whole fleet…”

and either by using Codemod AI or teaming up with our experts—boom: codemods or ast-grep rules get built
and insights that never existed before just show up 🪄

zero distraction for your engineers.

real-time dashboards.
across all your repos.
from the same tools your team already uses to automate the chore.

if you’re in the middle of a migration, ping me.
i’ll build your dashboard live on a quick call!

30-sec teaser 🎥

pls X-post with folks who need this ❤️
