Features and specs

What each product offers, as listed by its team.

Causr 8 features
Mastodon 5 features
  • Decision Tracking
    Capture project decisions, assign owners, due dates and rationale so important decisions never disappear into meeting notes.
  • Risk Management
    Record, prioritise and monitor project risks with ownership, severity and impact on delivery milestones.
  • Dependency Management
    Visualise how risks, blockers and decisions affect milestones and downstream deliverables.
  • Modern RAID Log
    A searchable, filterable alternative to spreadsheet RAID logs that stays active throughout the project lifecycle.
  • Stakeholder Management
    Instantly see every risk, blocker, decision and dependency owned by a specific stakeholder to improve accountability.
  • Milestone Management
    Connect every project item to the milestones it affects for clearer delivery oversight.
  • AI Meeting Capture
    Extract decisions, risks and blockers from meeting transcripts instead of manually updating project documentation.
  • Project Sessions
    Organise project updates by meeting or stand-up while keeping extracted items linked to the wider project.
  • Decentralization
    Mastodon is based on a federated network, meaning it's composed of multiple servers (or instances) that communicate with each other. This reduces the risk of a single point of failure and offers more control over data.
  • User Control
    Users can choose from various instances with different rules and themes, offering more control over the kind of community they want to be part of.
  • Ad-Free
    Mastodon does not rely on advertising for revenue, which means users can enjoy a social media experience without intrusive ads.
  • Open Source
    Mastodon is open-source software, allowing for greater transparency and the opportunity for the community to contribute to its development.
  • Privacy Features
    Mastodon offers comprehensive privacy features, including granular post visibility options and the ability to block and report users.

Possible disadvantages

  • User Base Fragmentation
    Because Mastodon is decentralized, users are spread out over many instances, leading to smaller, fragmented communities that might reduce the reach and variety of interactions.
  • Complexity
    New users might find the federated nature of Mastodon confusing, as they need to choose an instance and understand how different instances interact.
  • Scalability Issues
    Some instances may experience performance issues or downtime, especially smaller ones with limited resources, affecting reliability.
  • Content Moderation
    Each instance sets its own moderation policies, which could lead to inconsistencies in how harassment, spam, and inappropriate content are handled.
  • Feature Parity
    Mastodon might lack some features available on more mainstream social networks, such as advanced search capabilities or integrated multimedia tools.
