The machine cycle diagram that re-times itself — and your designs never leave your computer.

Short description — one paragraph, ready to paste
App for calculating and communicating your machine operations and cycle times. Cyclogram is a browser-based cycle-diagram editor for machine-design engineers. It models one repeating machine cycle: every actuator is a lane, every movement a bar with optional ramp-up and ramp-down. Bindings with signed offsets chain movements, so lengthening one re-times the bound chain that follows instead of forcing a redraw. Projects stay in the user's own browser.
Long description — three paragraphs
A machine's cycle usually lives in the designer's head and gets re-explained at every hand-off — to controls, on the assembly floor, in the customer meeting. The drawing that documents it, a cyclogram, is often assembled by hand or in a spreadsheet that knows nothing about the timing, so one changed movement means re-checking every number after it. Cyclogram is a browser editor built for that drawing: one repeating cycle, one lane per actuator, one bar per movement.
Each movement is drawn as the engineer times it — an optional ramp-up, a body, an optional ramp-down. Bindings pin one of a movement's four hooks to another movement or a timeline mark with a signed offset, so "the gripper opens 0.2 s after the slide is home" survives a change to the slide. Wrap folds the timeline into its repeating loop. It is a scheduling editor, not a simulator: no physics, no collision checking, no CAD.
Cyclogram runs at cyclogram.app in a current browser and installs from Chrome or Edge as an app; after the first sign-in it works offline, needing one online start a month to refresh the session. Projects, the library and the licence live only in the browser: no project reaches the server, which keeps an account e-mail and a password hash. The free edition keeps every editing feature within two actuators and six tasks; a Full licence lifts the caps, removes the watermark and adds Excel export, free during the beta.
Boilerplate — the "About" block for the foot of a release
Cyclogram is a browser-based cycle-diagram editor for machine-design engineers, and for any process built from timed, dependent steps. It is built local-first: projects stay on the user's own computer. In free public beta until 30 September 2026; the free edition stays free afterwards. cyclogram.app · [email protected]

Fact sheet
| Product | Cyclogram (the wordmark is set lowercase as "cyclogram" in the site header and logo) |
|---|---|
| Category | Browser-based cyclogram editor — also called a cycle diagram or motion diagram. A timing and scheduling editor; not a simulator, not CAD, not a Gantt or calendar tool |
| What it models | One repeating machine cycle. Each actuator is a horizontal lane; each movement is a bar with an optional ramp-up, a body and an optional ramp-down; bindings with signed offsets chain movements together |
| Core capabilities | Bindings on four hooks per movement (ramp-up start, body start, body end, ramp-down end), timeline marks and ruler, wrap view, reusable library, compare view, PDF and Excel export, 150-step undo per project |
| Who it is for | Machine-design engineers, and any process with timed, dependent steps — an embedded start-up sequence, a chemical batch procedure, a brew day |
| Website | cyclogram.app · editor at cyclogram.app/app/ · security and privacy at /security · guide for AI assistants at /ai |
| Availability | Live and in free public beta until 30 September 2026. Site and app carry © 2026 |
| Editions | Free (no licence file), Full (licence file), Enterprise (announced, in development — not shipped, and not to be described as available) |
| Free edition — caps | Every editing feature works within the caps of 2 actuators and 6 tasks. Larger projects still open, view and export, but editing them is locked until they fit the caps (or a licence is imported). Commercial use permitted, with no time limit |
| Free edition — watermark and exports | The on-screen timeline carries a tiled cyclogram.app watermark; the PDF export carries it by default and can be switched off in Preferences. Excel export is a Full-licence feature and is disabled in Free |
| Full edition | Unlimited actuators and tasks, Excel export, and watermark-free timeline and PDF. No per-feature tiering and no subscription |
| Licensing mechanism | A signed .mclic file imported once per browser, verified offline in the browser (ECDSA P-256 / SHA-256) with a local expiry check. No activation server and no phone-home. Issued to a person and tied to an account e-mail; either perpetual or valid until a date |
| Price during the beta | Every Full licence is free while the beta runs, requested through the in-app licence form or by e-mail to [email protected]. No price list is published anywhere; pricing after the beta is by e-mail |
| Account | Required to open the editor: an e-mail address and a password of at least 8 characters. Free, no card |
| Platforms | A website, nothing to install: any current Chrome, Edge, Firefox or Safari on Windows, macOS or Linux. Installs as a standalone app from Chrome or Edge, or via "Add to Home screen" on a phone |
| Offline use | Only the first sign-in needs a connection; the app then runs with no network. The cached session lasts 30 days and one online start refreshes it. Licence checks never contact a server |
| Time resolution | Snap grid of 0.1 s, 0.5 s, 1 s, 5 s, 10 s, 1 min, 10 min or 1 hour. Cycle time is derived from the last movement; the target cycle time is typed by the user |
| File formats | .mcyc project (plain indented JSON), .mclib single library entry, .mclibrary whole library with its folder tree, .mclic licence. Preferences export as plain .txt |
| Export formats | PDF: a single page rendered in the browser, page size computed from the content. Excel: an HTML table saved with an .xls extension, one cell per resolution unit. Both always print the full unwrapped cycle |
| Privacy posture | Projects, the library, preferences, the licence and the cached session live only in the user's browser (IndexedDB and localStorage) and are never uploaded. There is no server-side project storage and no cloud sync; clearing site data deletes them, so .mcyc files are the backup |
| What the server holds | An account e-mail address and a password hash (PBKDF2-SHA-256, 100,000 iterations, per-account salt), abuse counters stored as one-way hashes, and the contact details a user types into the optional in-app licence-request form. No machine designs |
| Cookies, analytics, trackers | No cookies (the session token lives in localStorage), no advertising, no tracking pixel, no third-party font, and therefore no cookie banner. Page views are counted by Cloudflare Web Analytics, which is cookie-free and stores no identifier; the single other third-party embed is Cloudflare Turnstile on the sign-up form |
| Hosting | Cloudflare: the site is deployed to Cloudflare Pages and account records live in a Cloudflare D1 database |
| Certifications | No SOC 2 report and no ISO 27001 certificate. GDPR compliance is self-assessed and the code audit is self-stated (most recently August 2026) |
| Interface languages | English, Deutsch and Slovenščina, selectable in Preferences. The ribbon, status bar and preferences translate; canvas popups and the library are English for now |
| Documentation | A 17-section manual built into the app, a 16-step interactive guided tour that runs on first launch and can be replayed, and 14 tips cards |
| Contact | [email protected] — the single address for pricing, licences, bug reports, feature suggestions, security reports and GDPR requests |
What Cyclogram is not — the errors we would most like to avoid
- Not a simulator. No physics, no collision checking. It flags two movements overlapping on the same actuator, which is a scheduling conflict, not a geometric one.
- Not CAD. No geometry, no models, no CAD import or export.
- Not a cloud tool. Projects never reach a server; there is no sync and no server-side copy of anyone's designs.
- Not a Gantt chart. One repeating cycle, times in plain seconds — not a schedule of dated tasks.
- Enterprise is announced, not shipped. Please do not describe multi-station projects, collaboration, version control or utilisation analysis as available.
