Changelog

Release notes for FlowFn. Each version links to its own page with the full list of changes. Newest releases appear at the top.

Versions

• v4.5.0 — 2026-07-12 — MCP servers open up, and knowledge files get bulk tools. The MCP tool picker now shows your whole platform-tool catalog by default — a searchable, logo'd picker instead of a short pre-cleared list — with FlowFn holding back only a curated high-impact set (payments, cloud, raw databases, custom API/MCP connectors, bulk-send). Agent Knowledge files now upload several at once and support multi-select + bulk delete. The agent editor adds a live slug-availability check as you type, always shows your app's branded public URL (or explains when the app has no domain yet), and agent public links resolve on your own subdomain/custom domain.
• v4.4.0 — 2026-07-12 — Search visibility for every public page. Agents, forms and visualizers gain the same Enable SEO control playgrounds have — plus SEO title, description and keywords overrides — and their public pages now emit proper titles and robots directives (no more URL-as-tab-title on shared links). On your own subdomain or custom domain, robots.txt now honors whichever kind of page your domain points at. Public pages on flowfn.com stay unindexed; your branded domain is the canonical home.
• v4.3.0 — 2026-07-12 — Meet Fen, and a dashboard-wide polish pass. FlowFn's assistant now has a name and a face — Fen appears in the AI chat, on empty states, error pages and celebrations, on the marketing site and social cards. Alongside: a ⌘K command palette, a first-run getting-started checklist, a proper mobile experience (back navigation, card layouts, adapted filters), stacking notifications in the bottom-right corner, real 404/error screens that keep you in the dashboard, and hundreds of consistency fixes across buttons, colors and light/dark parity.
• v4.2.0 — 2026-07-11 — AI builds everything, and your dashboard finally counts everything. The AI assistant's "What do you want to build?" now covers all eight artifact kinds — new Data sheet (typed columns + sample rows) and MCP server (attaches your existing workflows, agents and sheets as tools) join workflows, playgrounds, forms, visualizers, agents and streams. Analytics gains cards for agents, playgrounds, data sheets and MCP servers, and the Home page shows a compact all-features count strip. Plus: MCP servers render as a card grid with an explicit Edit action, client config is tabbed per provider, and every detail page carries a copyable dev-info footer (ID + created/updated).
• v4.1.1 — 2026-07-10 — Platform Access polish. The account's API access section is now Platform Access, with REST/MCP cheat-sheet tabs. Every record you drive over the API — apps, agents, streams, data sheets, playgrounds, forms, workflows, visualizers and teams — gains a one-click Copy ID (grab a team_id for X-Team-Id, or a record id for PATCH …/:id). The hosted-MCP connect screen adds per-client config cards (Claude, Cursor, VS Code, Gemini CLI, ChatGPT and more) with the token rendered as {token} (Copy still pastes the real one), and duplicating an MCP server now asks for confirmation.
• v4.1.0 — 2026-07-10 — Build FlowFn from anywhere. A new Platform API lets you create, update and list apps, agents, streams, data sheets, playgrounds, forms, workflows and visualizers programmatically — over a REST API (for Postman and your own apps, with an importable OpenAPI spec) and a management MCP server (connect Claude.ai, ChatGPT or Cursor and ask them to build for you). One rotatable Personal Access Token in your account Security settings authenticates both.
• v4.0.0 — 2026-07-04 — Host your own MCP server. Create an MCP, attach platform tools, data sheets, workflows and agents, and connect external AI clients (Claude Desktop, Cursor) to a token-authed endpoint that exposes exactly what you chose. Rotate the token any time; a copy-ready client config makes connecting copy-and-go.
• v3.11.0 — 2026-07-03 — Call your playground server functions from outside FlowFn — a new authenticated API (app code + secret) with per-function codes, real HTTP verbs, and ctx.method / ctx.query.
• v3.10.0 — 2026-07-03 — Know which page you're on. The playground client SDK gains flowfn.currentPage — the current page's slug ('' on the home page) — for active-nav highlighting and page-conditional logic in shared site JS.
• v3.9.0 — 2026-06-28 — Fixes for sites on your own domain. End-user sign-in now works on custom domains and subdomains (no more bouncing back to the login page); white-label sites no longer show FlowFn's cookie banner, analytics, or branding (browser tab, social previews and error page included); saving a data sheet that has secured (password) columns no longer fails; and a playground's End-user auth settings now keep their fields disabled until you enable sign-in.
• v3.8.0 — 2026-06-28 — Your own API key isn't limited by your plan. When AI runs on a team or personal API key (BYOK), plan AI restrictions no longer apply — you can use any available model or provider, because you're paying for it. Plan AI limits now cover only AI that runs on FlowFn's key. Admins can also exclude specific system AI providers (e.g. Gemini) from a plan's FlowFn-funded key.
• v3.7.0 — 2026-06-28 — One-call end-user auth. New ctx.auth.login / signup / changePassword / requestPasswordReset / resetPassword / logout compose signup & login & OTP password-reset flows for you (rate-limited, generic failures, password hashing + sessions handled). End-user auth settings gain a user-type column (separate admin / customer with one user table), a reset page, and OTP columns for password reset.
• v3.6.0 — 2026-06-28 — Call workflows & agents from stream code. A stream's Tools tab can now list the workflows and streaming agents its code may invoke with ctx.workflows.run(...) / ctx.agents.run(...) (only listed ones can run). The Code tab gains a cheat sheet of the full ctx API, and Tools shows copyable code snippets for AI, data sheets, workflows and agents.
• v3.5.0 — 2026-06-26 — Per-playground subdomains. On an app with a custom domain, your root playground stays at the domain root and any other playground can take a subdomain of it — give it a label and it serves at shop.yourdomain.com (point one CNAME; HTTPS issued automatically). Each subdomain site is independently search-indexable.
• v3.4.0 — 2026-06-23 — AI in streams. Bind a channel to Call AI and your team's AI model answers players in the room with no code, or call ctx.ai.call(...) from a stream function. Both billed to your team's AI credits.
• v3.3.0 — 2026-06-22 — Public usage limits. Every public surface (playgrounds, forms, visualizers, agents, streams, webhooks) now has per-plan daily limits so third-party traffic can’t run up surprise costs, with a new Public usage limits card on Billing. On the free tier, public AI runs on your own API key (BYOK), and playgrounds get a Refresh cache button.
• v3.2.0 — 2026-06-21 — Custom domains. Point your own domain (e.g. app.yourbrand.com) at a FlowFn app with automatic HTTPS — add the domain, set one CNAME, and we issue & renew the certificate. Public hosting shows it go provisioning → active.
• v3.1.0 — 2026-06-20 — Read & write data sheets from stream and workflow code. ctx.sheets(databaseId) is now available in stream Code functions and workflow Code tasks (the same SDK as playground server code) — insertRow / updateRow / query / deleteRow, naming the database per call and ownership-checked against your team. Agents could already read/write sheets via a read-write sheet tool.
• v3.0.0 — 2026-06-20 — Reuse & teams. Duplicate any asset (forms, visualizers, agents, streams, playgrounds, and data sheets), templates & the AI builder now cover agents and streams with a typed gallery filter for every kind, and agents can push results into a visualizer. For teams: new Billing and Viewer roles with scoped access, transfer an app or item to another team, more integrations as playground fetches, and recoverable data-sheet rows.
• v2.0.2 — 2026-05-12 — Fixes. A playground's Data tab keeps its linked database on refresh, and the data grid no longer shows placeholder values in empty cells.
• v2.0.1 — 2026-04-25 — Fixes. Moving between pages of a multi-page playground no longer flashes a loading screen, in-site links and redirects stay in-page, and password-protected playgrounds work on custom domains.
• v2.0.0 — 2026-04-05 — Playgrounds, data sheets & realtime. Build full multi-page sites with reusable components, server-side code (ctx.http + server data queries), AI that edits your whole site with preview-and-approve changes, and data-binding templates. New standalone Data Sheets with rich column types, server queries, and per-row owner actions. Plus Streams (realtime rooms for games & live apps), per-app subdomains, white-label publishing, and safer recoverable deletes.
• v1.0.1 — 2026-02-18 — Fixes. Interrupted agent and workflow runs recover automatically instead of hanging as "running", and you can retry a failed run in one click.
• v1.0.0 — 2026-01-15 — First production release. Visual & AI workflow builder with 60+ AI models and 100+ integrations, Forms with spam protection, shareable visualizers, AI Assistance for building faster, and Agents — autonomous AI workers you run interactively, on a schedule, or by webhook, with skills, approvals, and an embeddable chat widget. Content moderation and plan-based data retention across every surface.
