Features and specs

What each product offers, as listed by its team.

Mastodon 5 features
Sourcey 5 features
  • 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.
  • Startup offers with sources
    Company and program records attach the original vendor evidence, terms, and eligibility caveats; unknown eligibility stays unknown.
  • Agent Readiness report cards
    Task-level findings show what was tested, observed blockers, evidence, and conditions that remain unverified.
  • Public API and MCP
    People and agents can read the public record through the website, HTTP API, change feed, and MCP.
  • Versioned evidence
    Signed releases preserve the provenance and history behind published findings.
  • Focused public datasets
    Startup-credit and Agent Readiness JSON datasets expose the same records for downstream analysis.

Questions & Answers

As answered by people managing Mastodon and Sourcey.

What makes your product unique?

Sourcey's answer:

Sourcey ties startup offers and Agent Readiness findings to source evidence and versioned releases. A report card describes one agent task, its observed result, blockers, and unknowns. Offer records keep the vendor’s terms and eligibility caveats visible. The public record is free to read through the website, JSON, API, and MCP.

How would you describe the primary audience of your product?

Sourcey's answer:

Founders comparing startup offers, developers evaluating whether an agent can complete a specific task with a service, and agents that consume the public record through HTTP or MCP.

Why should a person choose your product over its competitors?

Sourcey's answer:

Choose Sourcey when you need the original source behind an offer or a task-level account of what an agent could actually do. It shows uncertainty and release history alongside the finding. Sourcey does not apply for offers or redeem credits on a founder’s behalf.
