What is Flame?

Self-hosted dashboard that finished its feature arc and stopped shipping in 2023.

Flame is a self-hosted startpage for homelab services — app tiles, bookmarks, weather, and a search bar. The feature set it set out to build was finished across 2021 and 2022: custom app descriptions, Docker secrets support, a secondary search provider, and a custom theme editor. The most recent release in this feed is v2.3.1 from July 2023, and it is entirely bug fixes.

What is Slack?

Slack now hosts any A2A agent without Slack-specific code.

Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.

Flame vs Slack: editorial side-by-side

0.0

Self-hosted dashboard that finished its feature arc and stopped shipping in 2023.

◆ Current state

Flame is a self-hosted startpage for homelab services — app tiles, bookmarks, weather, and a search bar. The feature set it set out to build was finished across 2021 and 2022: custom app descriptions, Docker secrets support, a secondary search provider, and a custom theme editor. The most recent release in this feed is v2.3.1 from July 2023, and it is entirely bug fixes.

◆ Where it's heading

The arc reads as a project reaching completion rather than one under active development. Later releases shifted from adding capability to correcting the edges of what already existed — search-provider interactions, iOS input rendering, theme editor field sizes, label wording. There has been nothing since.

◆ Prediction

Nothing in these entries suggests further releases; anyone deploying Flame should treat the current version as the final one unless the project resumes.

Slack now hosts any A2A agent without Slack-specific code.

◆ Current state

Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.

◆ Where it's heading

Slack is lowering the cost of putting outside agents in front of its users: first skills as code, then MCP pointers for coding agents, now a standard protocol in place of the Slack app model for agents. The platform is positioning itself as the place where agents built anywhere meet the people who use them.

◆ Prediction

Expect more A2A follow-ups, such as agents appearing in Slackbot or skills surfaces and richer Agent Card features, given how fast the agent releases have stacked up since October.
