Simple Kanban boards,
yours to keep.

The tracking tool your agile team actually opens on Mondays. No layers. No noise.

Onion is a Kanban board built for teams that document as they move, not after. You sign in, create a board, start using it. No onboarding module, no tour, no PM pushing a Slack integration on you.

OUR PHILOSOPHY

Complexity is easy. The hard part is knowing what not to build.

Anyone can add features. The hard part, the part almost nobody does, is having the courage not to build them, even when a user asks.

Project management tools start simple and grow until they weigh more than the work they're meant to help with. Tabs, integrations, automations, AI, views, modules, dashboards, permissions. All beautiful in the demo. All exhausting on Monday morning.

Onion works the other way. Layer by layer, we remove what isn't needed. If after a year a feature still isn't essential, we cut it. If a decision simplifies the product at the cost of an edge case, we take it.

A product for everyone is a product for no one. This one's for you.

WHO IT'S FOR

For teams that work, not for teams that configure tools.

If you do standups, sprints, or just need to see where things stand without navigating five menus, this is for you.

Agile teams with daily tracking

Standups, planning, retros. Onion shows you the real state of the sprint without having to "open the reports module" or build a custom view. The Doing column is the report.

Squads that document as they build

Each card is a mini-document: long description, custom attributes, links, context. Enough so information doesn't get lost. Not so much that nobody maintains it.

People tired of Jira

Onion doesn't replace a PMO. It replaces the Jira board nobody on the team wants to update. If you've ever stared at a 4-second loading screen just to move a card, you know what we mean.

WHAT IT DOES

A few things. Done well.

Boards that load fast

No endless onboarding, no tour, no welcome modal. Login with Google, create a board, start.

Custom attributes, without building a parallel Airtable

Add the fields your team actually uses, priority, estimate, owner, client tag, directly on cards. Zero code.

Genuinely private

Your boards are yours. We don't sell data, we don't train models on your cards, there are no third-party trackers running in the app. If you want to leave, you export everything in one click.

Built with care, not translated on autopilot

Made in Buenos Aires, designed for teams that want an honest tool. Every line of copy was written by a human who actually uses the product.

Public boards shareable via link

Share a board with a client, a freelancer, or a quarterly OKR without inviting them to an "organization" or giving them a paid seat.

JUST AS IMPORTANT AS WHAT IT IS

What Onion is not (and why we're not embarrassed).

Some decisions define a product by what it rejects, not what it accepts. These are ours. If any of these is a dealbreaker, better to know now.

Not a full project management suite.

Asana and Jira already exist. Competing on features is losing. Competing on simplicity is winning.

Not a real-time collaboration tool.

Live cursors mean high technical complexity and low real differentiation. If your team needs serious synchronous collaboration, Onion isn't the choice. If it needs to see updated status, yes.

Not an app with generative AI.

AI adds layers: suggestions, autocomplete, "smart" dashboards. Onion removes layers. They're opposing forces, and we chose a side.

Not a product for everyone.

A product for everyone is a product for no one. The focus on LATAM and Spanish isn't a limitation, it's the point. There are companies better equipped to serve the entire world. We don't want to be one of them.

Not a Trello clone with more features.

Trello started simple and lost its direction as it grew. Onion exists precisely to not repeat that path. If what you need is Trello-with-more-things, there are already options.

Not enterprise-ready.

SSO, granular roles, audit logs, SOC2 compliance. All of that carries a complexity cost that deforms the product. We won't add it to close a contract.

THREE STEPS

Three steps. There is no fourth.

Create a board.

Add columns and cards.

Your flow, not ours. If you want To do / Doing / Done, great. If you want Idea / Validation / Building / In production / Broken, also great.

Come back tomorrow.

The card is still where you left it. No email notifications, no forced newsletter, no "we miss you" after three days.

FAQ

What you're probably wondering.

Can I use Onion with a large team?

You can. But we'll be honest: if you need fine-grained roles, audit logs, or SSO, we're not your tool. Onion is designed for small and medium teams that want to see their work, not manage it from an admin console.

What happens to my data?

It's yours. You can export it whenever you want, in an open format. We don't share it with third parties, we don't use it to train AI, we don't sell it to brokers. If we ever shut down, you'll have a month to get everything out.

Is there a mobile app?

The web works on mobile and is what most teams use. A native app isn't a priority right now. If enough people ask, we'll revisit it.

Are there integrations with Slack, Notion, or GitHub?

No. See the What Onion is not section.

Who's behind the project?

One person. Indie. From Buenos Aires. Which matters because it means the roadmap isn't decided by a committee, it's decided by you when you use it and tell us what's missing.
