--- title: Trello canonical: https://saasranked.com/software/trello/ category: Project Management Software points: 74 rank: 8 of 11 facts_checked: 2026-10-08 --- # Trello Card-and-board task tool with a free plan for up to 10 collaborators and paid plans from $5 per user. 74 points out of 100. #8 of 11 project management tools. Vendor: Atlassian. Website: https://trello.com/ - Standard costs $5 per user a month billed yearly, so five people pay $25 a month [1]. - The free plan allows up to 10 collaborators per Workspace and 10 boards [1]. - Timeline, calendar and dashboard views need Premium at $10 per user [1]. - Trello's help centre says it has no built-in task dependencies [2]. - Apps are listed for Windows, macOS, iOS and Android [3]. Verdict: Trello suits small teams that want boards, custom fields and automation at a low price: five people pay $25 a month on Standard [1]. The free plan covers up to 10 collaborators [1]. The catch is planning depth: Trello says it has no built-in task dependencies, and its pages show no workload view, time tracking or forms [1][2]. In 2024 an API was abused to link emails to about 15 million profiles [4]. Best for: Small teams that want a simple board at a low price. ## Points | Criterion | Line | Value | Points | Note | |---|---|---|---|---| | Price | Cheapest paid plan for 5 people | $25/mo | 12/12 | Standard, $5 per user a month billed yearly, times 5 users [1]. | | Price | Free plan | Yes | 6/6 | Free plan with unlimited cards and up to 10 boards per Workspace [1]. | | Price | People on the free plan | 10 | 4/4 | The pricing page says free for up to 10 collaborators per Workspace [1]. | | Views | Board view | Yes | 3/3 | Boards are on every plan; Free allows up to 10 boards per Workspace [1]. | | Views | Timeline or Gantt view | Yes | 7/7 | Premium lists a Timeline view; the page does not use the word Gantt [1][7]. | | Views | Calendar view | Yes | 2/2 | Premium lists a Calendar view and a Workspace Calendar view [1]. | | Planning | Task dependencies | No | 0/7 | Trello's help article says it has no built-in task dependency management [2]. | | Planning | Workload view | Not published | 0/6 | Not published on the vendor's pricing page or the Timeline view article [1][7]. | | Planning | Built-in time tracking | Not published | 0/5 | Not published on the vendor's pricing page [1]. | | Planning | Custom fields | Yes | 5/5 | Standard lists Custom Fields [1]. | | Planning | No-code automation rules | Yes | 6/6 | Pricing page says no-code automation is built into every board; free plan has 250 command runs a month [1]. | | Teamwork | Guest access for clients | Yes | 5/5 | Standard lists single-board guests; Enterprise lists multi-board guests [1]. | | Teamwork | Request forms | Not published | 0/3 | Not published on the vendor's pricing page [1]. | | Teamwork | Reports and dashboards | Not published | 0/5 | Premium Dashboard view charts one board's cards; no cross-project report is described [1][6]. | | Security | SOC 2 Type II or ISO 27001 | Yes | 7/7 | Atlassian's ISO/IEC 27001:2022 page lists Trello under relevant products; scope is not spelled out [8]. | | Security | SAML single sign-on | Yes | 4/4 | Enterprise lists free SSO with Atlassian Guard; the Enterprise page describes setting up SAML SSO [1][9]. | | Security | Two-step sign-in | Yes | 3/3 | The Free plan feature list includes 2-factor authentication [1]. | | Apps and API | Apps | Windows, macOS, iOS, Android | 8/8 | Platforms page links a Microsoft Store listing, a Mac App Store listing, an iOS App Store listing and Google Play [3]. | | Apps and API | Public API | Yes | 2/2 | Atlassian's developer site documents the Trello REST API, including card endpoints [5]. | ## Plans | Plan | Price | Per month (USD) | |---|---|---| | Free | Free [1] | $0 | | Standard | $5/user/month [1] | $5 | | Premium | $10/user/month [1] | $10 | | Enterprise | $17.50/user/month [1] | $17.50 | Prices are per user a month billed yearly; billed monthly, Standard is $6 and Premium $12.50 [1]. ## Strengths - Five people pay $25 a month on Standard, billed yearly [1]. - The free plan lets up to 10 collaborators per Workspace use boards, with two-factor sign-in included [1]. - Standard adds custom fields and single-board guests; automation is built into every board [1]. - Official apps for Windows, macOS, iOS and Android, and a documented REST API [3][5]. ## Limits - Trello says it has no built-in task dependency management [2]. - Timeline, calendar and dashboard views need Premium [1]. - The Dashboard view is opened from one board's menu; no cross-project report is described [6]. - The free plan allows up to 10 boards per Workspace and 250 command runs a month [1]. - In January 2024 a threat actor used a Trello API to link email addresses to about 15 million profiles [4]. ## Concerns - BleepingComputer reported on 23 January 2024 that a threat actor used a public Trello API to match email addresses to profile data for about 15 million accounts; Trello then restricted lookups by email for unauthenticated users [4]. ## Sources 1.
