Standout Differences
Three unrelated job categories
3Cols is a niche developer utility for code snippets, Accelo is an enterprise-leaning agency operations platform, and Acunote is a small-team agile tracker. Buyers evaluating these against each other should recognize they're not interchangeable — pick based on the actual workflow you're trying to solve.
3Cols, Accelo, acunote.com
Pricing spans free to enterprise custom quotes
3Cols is entirely free, Acunote is free for up to 5 users with paid plans from $49/month, and Accelo requires a custom quote with a minimum team size, with third-party estimates putting entry pricing around $20 to $30 per user per month. This is a much wider spread than a typical head-to-head comparison.

Acunote flags its own low profile
Acunote's own description notes it is 'a small, lower-profile product with limited recent public activity.' That's worth weighing directly against Accelo, which is positioned as an actively marketed AI-powered platform, if long-term product momentum matters to your decision.

Accelo is the only one built around billing and client relationships
Accelo bundles sales pipeline, ticketing, retainer management, and billing into one system — a scope neither 3Cols nor Acunote attempts. If your need is running client-facing agency operations rather than tracking code or sprints, only Accelo is built for that.

Frequently Asked Questions
Are 3Cols, Accelo, and Acunote actually alternatives to each other?
No. They serve entirely different jobs — 3Cols is a free code snippet manager, Accelo is a professional services automation platform for agencies, and Acunote is a Scrum/agile project tracker. A buyer would rarely have all three as genuine options for the same need.
Which one should an agency choose to manage client billing and retainers?
Accelo, and it's not close — it's the only one of the three built around sales pipelines, tickets, retainers, and billing in one system. Neither 3Cols nor Acunote offers billing or client-relationship features based on their descriptions.
Which is best for a small dev team wanting free Scrum boards?
Acunote, which offers sprint boards, burndown charts, and wiki-based collaboration free for up to 5 users. 3Cols is free too, but it's a code snippet manager, not a Scrum or sprint-tracking tool, so it doesn't cover the same need.
Is 3Cols a project management tool?
No. 3Cols is described as a free cloud-based code snippet manager that lets developers store, organize, and share snippets in real-time collaborative three-column boards — it's a developer utility, not a project or task management system.
Is Acunote still actively maintained?
Its own product description characterizes it as 'a small, lower-profile product with limited recent public activity,' which is a meaningful signal to weigh if you need active development and support. Buyers prioritizing an actively developed platform may lean toward Accelo instead, though that comparison only applies if you actually need Accelo's agency-operations scope.
