InvisibleAPI is a unified social publishing and insights API for developers and AI agents. Instead of maintaining separate integrations for every platform, you send one request. InvisibleAPI handles OAuth token lifecycles, media processing, rate limits, and retries. Built by EmbedSocial on 15+...

InvisibleAPI's answer
InvisibleAPI is built as developer infrastructure rather than a bloated social media management dashboard. Key differentiators include:
ReleasePad's answer:
Most changelog tools assume you'll write the release notes. ReleasePad assumes you won't. It connects to your GitHub repo, drafts release notes from merged PRs and commits using AI, and waits for one click of approval before publishing. From there it distributes to three places at once: a 4.3kb in-app widget, a public hosted SEO page, and a machine-readable Markdown URL that ChatGPT, Claude, and any other model can read. That third channel is the part nobody else ships, when a user asks an AI assistant "what changed in this API?", ReleasePad makes sure the assistant has the real answer instead of guessing.
InvisibleAPI's answer
Most social API wrappers merely forward requests and forward provider failures. When third-party platform APIs break or change without notice, downstream products break.
InvisibleAPI acts as true infrastructure. It absorbs platform-specific quirks, rate limits, token lifecycles, and delivery tracking behind a single, consistent API. You get:
ReleasePad's answer:
Pricing and effort. Beamer starts at $49/mo and scales with monthly active users; Canny's Pro plan starts at $79/mo and scales with tracked users. ReleasePad is $35/mo flat per product, same price for a team of 1 or 200, no per seat fees, no usage cliff as you grow. And the DIY route (Notion, a blog, a Confluence page) is only free until you count the hours: you still write every entry by hand, still maintain the page, and still get no in-app surface or analytics. ReleasePad takes 30 seconds and one line of code to install, drafts the writing for you, and tells you which updates people actually opened.
InvisibleAPI's answer
The primary audience is developers and engineering teams building social publishing features directly into their own applications.
InvisibleAPI is built specifically for:
Product teams: SaaS founders and engineering teams shipping in-app social publishing without building custom platform integrations.
AI agent developers: Builders using Claude, Cursor, or autonomous agent frameworks who need an MCP-native tool to publish and read social data.
Agencies: Teams managing multiple client social accounts across isolated multi-tenant organizations with role-based access.
ReleasePad's answer:
SaaS teams that ship faster than they communicate, indie hackers, solo founders, and small-to-mid product and engineering teams who merge PRs weekly but have no dedicated marketing or docs person. Typical buyer is a founder, head of product, or engineering lead at a product-led company where releases are constant and invisible. 153+ teams use it today, with 15,793+ release notes published..
InvisibleAPI's answer
The team behind invisibleAPI has operated social media infrastructure in production for over 15 years. Over that time, product teams repeatedly asked the same question: "We love what your platform does, but we need the capability inside our own application."
Every team that tried building it internally hit the identical wall: juggling multiple platform OAuth flows, silent token expirations, sudden breaking changes, and conflicting rate limits.
We had already solved these operational problems in production. We created InvisibleAPI to expose that battle-tested plumbing as a clean, unified API so developers and AI agents never have to rebuild it from scratch.
ReleasePad's answer:
I've worked in technology companies all my life. I've kept watching teams merge twenty PRs a month while their end users, and their prospects, assumed the product had stalled. The changelog was always the last thing anyone wrote and the first thing that fell off. ReleasePad's premise is that if it isn't announced, it didn't happen: buyers check your pulse before they pay, and now AI assistants answer questions about your product whether or not you've given them anything accurate to read. The June 2026 launch of machine-readable Markdown output made that second audience explicit, your changelog now has human readers and agent readers, and both should get the same source of truth.
