What is Buttondown?

A near-daily fix stream, with flexible monthly RSS scheduling the only real addition.

Buttondown publishes a dated entry almost every day, and the overwhelming majority are single bug fixes, several credited by name to the subscriber who reported them. The current window is nine-tenths repair work — stretched newsletter icons in the archive, a portal 403 for subscribers with many accounts, rejected WebP uploads, cursor placement between stacked tables. Two genuine features sit at the window's edges: filtered blocks on July 31 and flexible monthly RSS scheduling on August 1. Every entry is titled with its date alone, so the titles carry no signal until rewritten.

What is Gumloop?

Gumloop stops selling agent-building and starts shipping a finished agent

Gumloop ships weekly digests that bundle connector work, governance controls, and model adds in one post. The platform underneath now covers Company Brain syncing from any connector, MCP coverage spanning ads, SEO, social, and enterprise suites, per-role model and connector policy, and a skill library kept in sync with a GitHub repo. The two newest releases change the shape of the product: Gumball, a first-party personal agent with its own standing jobs, and managed tunnels that let agents reach MCP servers running inside a customer's own network.

5.0

A near-daily fix stream, with flexible monthly RSS scheduling the only real addition.

◆ Current state

Buttondown publishes a dated entry almost every day, and the overwhelming majority are single bug fixes, several credited by name to the subscriber who reported them. The current window is nine-tenths repair work — stretched newsletter icons in the archive, a portal 403 for subscribers with many accounts, rejected WebP uploads, cursor placement between stacked tables. Two genuine features sit at the window's edges: filtered blocks on July 31 and flexible monthly RSS scheduling on August 1. Every entry is titled with its date alone, so the titles carry no signal until rewritten.

◆ Where it's heading

The shape here is a maintained product rather than one under redirection: the fix stream is dense, specific and largely user-reported, which reads as a small team with an engaged base rather than as instability. The features that do land are narrow gap-fillers — letting a monthly send fall on the 29th, making one section of an email visible to a single audience type — each closing a limitation someone actually hit. Filtered blocks are the only recent change that adds a primitive instead of a setting, since audience-scoped sections are where segmentation inside a single send begins.

◆ Prediction

The likeliest next step is more surface built on filtered blocks, as audience-scoped content is the one recent addition with somewhere further to go. Otherwise the daily fix cadence should simply continue; nothing in this window points to a larger change.

Gumloop stops selling agent-building and starts shipping a finished agent

◆ Current state

Gumloop ships weekly digests that bundle connector work, governance controls, and model adds in one post. The platform underneath now covers Company Brain syncing from any connector, MCP coverage spanning ads, SEO, social, and enterprise suites, per-role model and connector policy, and a skill library kept in sync with a GitHub repo. The two newest releases change the shape of the product: Gumball, a first-party personal agent with its own standing jobs, and managed tunnels that let agents reach MCP servers running inside a customer's own network.

◆ Where it's heading

Two arcs run in parallel. The plumbing is being hardened for enterprise deployment — private-network MCP, key-pair Snowflake auth, permission-aware Brain sources, audit logs, role-scoped connector access — while the product moves up the stack from a canvas where customers assemble agents to a packaged agent that arrives already knowing what to do. Connector breadth is the moat they widen most consistently, at roughly two to three new MCPs per release.

◆ Prediction

Expect Gumball to accumulate more built-in jobs and exit beta, and the MCP catalog to keep expanding at its current two-to-three-per-release cadence.
