Osmo CLI vs Robolly

Osmo CLI 23

Local-package reading, since the owner runs the CLI. Installs from npm. The vendor's skill README (revised 15 October 2026) states Node 22 or later, Git 2.29 or later, FFmpeg, and Studio on Apple Silicon macOS and Linux x64 and arm64 (glibc), while the npm README read on 8 October said any OS; the current npm README couldn't be read, so 15 is kept as a partial (15). The source is private, so there is no public CI or test suite (0). No public issue tracker for the CLI. Support is an email address (5). Versions are semver-shaped with preview tags, but no changelog was found, and osmo share --video FILE in 0.1.17 became osmo share FILE by 0.1.19 without a published note (3). Version 0.1.19 on 8 October, not declared stable (0). 15 + 0 + 5 + 3 + 0 = 23.

Robolly 48

Hosted lines. The footer links an UptimeRobot status page, but it loads its figures from /api/, which stats.uptimerobot.com's robots.txt disallows, so the page showed no monitors or history (10 of 20 for a page that exists) and no history was read (5). A hard limit of 3 renders a second is published (15). The rate-limit error code and advice to send renders one at a time, and identical renders are cached for 45 days at no cost, which makes a retry safe; there's no Retry-After or backoff interval (8 of 15). No SLA found (0). The API isn't labelled beta (10). 10 + 5 + 15 + 8 + 0 + 10 = 48.

Osmo CLI 10

Graded on the paid hosted service the CLI depends on, by the published rubric. No x402, MPP or L402 in the OAuth metadata or the skill (0). osmo.inc/pricing, terms and privacy render only in the browser, and the 8 October prices were read from the site's script, which this method no longer reads, so no price is readable (0). The skill README says model runs use the account's plan, which includes a free monthly allowance, without saying whether a card is needed, so half (10). A person has to create an account and approve the device login in a browser (0). 0 + 0 + 10 + 0 = 10.

Robolly 35

No x402, MPP or L402 (0). Plan prices are public and a table gives the credit cost of each format and size (15 of 20). 7-day trial with no card (20). A person signs up, then copies the key or approves OAuth (0). 0 + 15 + 20 + 0 = 35.

Osmo CLI 34

API checklist adapted to a CLI. No OpenAPI or command schema is published on a docs page. The model input schemas recorded on 8 October came from the product's own catalogue API at studio.osmo.inc/api/resources, which this method no longer reads, so the contract line has nothing behind it (0). The skill's SKILL.md is Markdown written for agents, with a command table, and osmo.inc/llms.txt now links the CLI page; the package's README, SETUP.md and DEPLOY.md were read from the 0.1.19 tarball on 8 October (10). Help text in the 0.1.19 bundle states what each command is for and when to pick share over studio deploy, per the 8 October check (12). Typed inputs with enums and ranges were read only from the catalogue API, so none remain (0). An example per command and JSON output shapes in DEPLOY.md, and a command table in the skill, but no reference for the roughly 50 error codes (8). Semver versions with no changelog (4). 0 + 10 + 12 + 0 + 8 + 4 = 34.

Robolly 57

No OpenAPI or other machine-readable contract found for the REST API, and the MCP server is closed. The MCP page lists all nine tools and get_template_modifications returns each template's keys, constraints and examples at run time (8 of 25, on that partial evidence). llms.txt indexes the docs (10). The MCP page says what each tool does, which tools change templates or spend credits, and that there is no delete tool (14 of 20). Modification keys follow {element-name}.{modification-key} with constraints from the template rather than a fixed schema (7 of 15). Request examples throughout and an error code table with eight codes (13 of 15). /v1 paths with no changelog (5 of 15). 8 + 10 + 14 + 7 + 13 + 5 = 57.

Osmo CLI 33

Closed source. The skill README says the CLI, renderer and resource packages are proprietary, and the npm packages carried no licence field or LICENSE file on 8 October. The terms of service render only in the browser and were read on 8 October from the site's script bundle, which this method no longer reads, so no licence terms are readable (0, as for other listings whose terms were only ever read from a script bundle). The privacy policy and terms were read the same way, so no data-handling statement remains (0). No deprecation policy or dated notices (0). The CLI bundle read on 8 October contacts only studio.osmo.inc and contains no analytics hosts, though telemetry isn't documented either way; the AI providers named in the struck privacy policy no longer count. Partial kept (10). 0 + 0 + 0 + 10 = 10.

Robolly 49

Closed service under terms effective 8 April 2026 from Avantis Innovations LLC in Wyoming. The terms can change without notice (15). The privacy policy of the same date covers Google sign-in and Sheets data, says spreadsheet rows aren't kept beyond a render and account data is deleted with the account, and otherwise names no periods (10 of 30). No deprecation policy or notices (0). Hosting is described only as third-party vendors, with no processors or locations named, while the footer says Made in EU (2 of 20). 15 + 10 + 0 + 2 = 27.

Osmo CLI 70

Read from the 0.1.19 bundle and docs on 8 October and the skill re-read on 5 November, not from a run. The skill grew from 255 bytes to 9,686 bytes on 15 October, a compact guide with a command table, every command takes --json, and lists default to short pages (18). --limit and --cursor on lists, --type on resources and --open on comments (15). Errors are JSON with a code, a message, a next command and retryAfter where it applies, with exit code 2 for usage errors, though only one error is documented (14). osmo run sends an Idempotency-Key and retries network errors, repeating unshare is documented as safe, and a failed upload reports the share to retry against (16). Few required arguments, and no SDK in any language (7). 18 + 15 + 14 + 16 + 7 = 70.

Robolly 75

Nine MCP tools (25). The renders list pages with a cursor, and templates are found by name (14 of 20). Errors carry errorCode and developerMessage with eight documented codes (17 of 20). Identical renders are cached for 45 days, so repeats are free and safe, the MCP server has no delete tool, and annotations couldn't be read on the closed server (12 of 20). Renders return the file synchronously by default, but there's no SDK (7 of 15). 25 + 14 + 17 + 12 + 7 = 75.
