Abyssale vs DynaPictures

Abyssale 85

API version v2026-10-29, eight days before this check (30). Fifteen dated API versions between 21 August and 29 October, MCP server releases 1.0.0 (1 September) to 1.2.0 (7 October), and SDK releases in October (20). Closed service with a changelog and RSS feed, help@abyssale.com and in-app chat, which we didn't test (12 of 15). com.abyssale/mcp is in the official MCP registry under a domain-verified namespace, and the Node.js (1.9.0) and Python (1.7.0) SDKs were both released on 21 October 2026 (15). Both SDKs are current; their repositories weren't read (8 of 10). 30 + 20 + 12 + 15 + 8 = 85.

DynaPictures 4

No changelog, release notes or dated API change was found, and the MCP server card gives version 1.0.0 with no date (0). No dated changes since 8 August (0). Support by email and contact form, not tested (4 of 15). Not in the official MCP registry and no API SDKs (0). No public package or repository (0). 0 + 0 + 4 + 0 + 0 = 4.

Abyssale 85

20 MCP tools (15 for 11 to 30), plus 5 because OAuth scopes per tool group let a client be approved for reads only (20 of 25). Design listings search by words in any order, filter by project, orientation, size, format and dates, sort and order, and say honestly when a page is past the end; listing tools refuse unsupported options rather than ignore them, per MCP 1.2.0 (19 of 20). One envelope with an id to branch on, and error docs that say which errors a retry never fixes (19 of 20). The permissions page marks each tool read-only, mutating or destructive, but MCP annotations couldn't be confirmed on the closed server, and generation has no idempotency key (12 of 20). Official Node.js and Python SDKs with retry behaviour and polling helpers (15). 20 + 19 + 19 + 12 + 15 = 85.

DynaPictures 45

The MCP tool definitions weren't read (listing them needs a session), and llms.txt describes groups that include layer-by-layer design authoring, so the count is unknown. REST responses are small objects with image URLs (12 of 25). Template and generated-image listings, with no field selection documented (10 of 20). Errors are JSON with a message and documented statuses, without codes (12 of 20). Requests aren't idempotent, by the vendor's own note, though identical image URLs are served from cache without a credit (6 of 20). An Editor SDK for embedding the editor, and no API client SDKs (5 of 15). 12 + 10 + 12 + 6 + 5 = 45.

The MCP server uses OAuth through Auth0 with scopes per tool group (read:design, write:design, delete:design, import:design, generate:banner, read:credits and others), enforced alongside the user's workspace role, and approval is per client connection. The REST API uses a workspace x-api-key with no scopes documented (28 of 30). A client can be approved for reads only, and deleting needs its own scope, but nothing on the server asks for confirmation; the docs leave that to the client per the MCP spec (17 of 20). Tools return the workspace's own designs and fonts; image layers can point at outside URLs (10 of 15). No audit log or per-call record was found (0). No security.txt, disclosure policy, bug bounty or certification found (0). 28 + 17 + 10 + 0 + 0 = 55.

DynaPictures 26

One API key per user with the user's full access, not limited to workspaces or actions; a new key is requested by email to support, with no rotation in the account (10 of 30). No read-only mode, and the MCP server can author and change designs (3 of 20). Tools return the account's own templates and renders; image layers accept outside URLs (10 of 15). A list of generated images, with no audit log documented (3 of 15). No security.txt, disclosure policy, bug bounty or certification found (0). 10 + 3 + 10 + 3 + 0 = 26.

Abyssale 98

A 424 KB OpenAPI file at developers.abyssale.com/api.yaml with 34 operations, from which the reference pages are generated (25). A detailed llms.txt that states the base URL, auth, rate limits, error envelope and webhook signing up front (10). Pages say what each endpoint is for and when to use another, such as synchronous versus asynchronous generation and designs versus workspace templates, and the MCP permissions page says what each tool can break (19 of 20). Typed parameters with enums, ranges and required fields across layers and formats (14 of 15). One error envelope everywhere, an error catalogue with machine-readable ids and what to do for each, and worked examples (15). Date-based versions named in every response and a dated changelog in Keep a Changelog form with a Breaking section first; the MCP server has its own semver changelog (15). 25 + 10 + 19 + 14 + 15 + 15 = 98.

DynaPictures 82

OpenAPI 3.1 at dynapictures.com/openapi.json with 20 paths (25). llms.txt, auth.md and an agent skill in Markdown (10). llms.txt says when to use the product and when it's a poor fit, and the skill gives call order for each job (17 of 20). Enums for formats and options, with layer overrides keyed by layer name (12 of 15). Request examples throughout and a status table in the skill, but the API reference's Errors section is unedited Slate template text about kittens (9 of 15). No URL version, additive changes, removals announced six months ahead with Deprecation and Sunset headers, and no changelog (9 of 15). 25 + 10 + 17 + 12 + 9 + 9 = 82.

Abyssale 71

Closed service under terms of service version 3 of 21 July 2026, from a Paris SAS with its register number (15). The privacy policy and terms agree on EU hosting on AWS Ireland, deletion timelines and breach notice within 72 hours, but AI model training on anonymised customer content is on by default with a workspace opt-out, and anonymised data may be kept indefinitely (20 of 30). The changelog has Deprecated and Removed sections and refers to a deprecation policy that covers stable endpoints but not alpha ones; the policy's notice period wasn't found (14 of 20). Subprocessors named with locations, among them AWS Ireland, Auth0, Brevo, Intercom and AI providers including OpenAI, Anthropic, Black Forest Labs and Google, some outside the EEA (20). 15 + 20 + 14 + 20 = 69.

DynaPictures 63

Closed service under terms (revision 2/2026) from DynaPictures GmbH in Freiburg, for business customers (15). The privacy policy names the controller, keeps generated images as long as needed or until deleted, gives plan image retention (3 months on Lite), and says the named AI providers don't train on API inputs under their API terms; other periods follow bookkeeping law (20 of 30). The OpenAPI file commits to six months' notice before removing an endpoint or field, with Deprecation and Sunset headers (16 of 20). AI sub-processors named with addresses (OpenAI, Google, Black Forest Labs, Replicate) and FastSpring for payments, while hosting providers aren't named (12 of 20). 15 + 20 + 16 + 12 = 63.

Abyssale 35

No x402, MPP or L402 (0). Seat prices are public and the credit cost of every output is published to the format, with worked examples, but a credit's price outside the plan wasn't found (15 of 20). 14-day free trial with no card (20). A person signs up in the browser; the MCP OAuth flow needs a human login (0). 0 + 15 + 20 + 0 = 35.

DynaPictures 30

No x402, MPP or L402 (0). Image allowances per plan and AI credit packs ($20 for 1,000 credits) are public, but plan prices are filled in by the FastSpring script and weren't readable (10 of 20). Free plan and a 14-day trial with 30 API credits, no card (20). auth.md says a person has to copy the key; there is no OAuth or programmatic key (0). 0 + 10 + 20 + 0 = 30.
