The repository has 18 commits since then (web UI changes, the URL fix, Weblate translations, a Docker thread setting and a CI runner move), the latest on 25 October. VERSION still reads 1.9.6, and per-commit Docker images aren't releases. The official MCP server @libretranslate/mcp last tagged v1.0.2 on 17 May 2026 (0). Issues per the 1 October check, not re-read on 4 November, since GitHub's pages refuse us (127 open, newest labelled by an automated triage bot, some with 1 to 4 comments) (15 of 25).

Self-hosted, the package reading would score far higher, with CI across Python 3.8 to 3.14 and a 1.x release line.\n- TranslatePlus (45): Hosted lines. status.translateplus.io is the vendor's own page; on 6 November 2026 it showed 'All systems unknown' and a last update of 22 January 2026, with data loading by script (5). No incident history to read (5).

No scopes or read-only keys (5). Translations return the caller's own text, so little untrusted content (10). llms.txt claims request logging and an analytics dashboard, which we couldn't see without an account (5). translateplus.io/.well-known/security.txt returns 404 and no disclosure policy was found; llms.txt says 'SOC 2 compliant' and 'SOC 2 Type II certified infrastructure' with no report or auditor named (0). 15+5+10+5+0 = 35.\n\n### Payments \u0026 pricing: LibreTranslate +10\n\n- LibreTranslate (40): No x402, MPP or L402 (0). Flat monthly plans with published limits, $29 Pro and $58 Business, not per-unit pricing (10). No hosted free tier or trial, only a 7-day money-back guarantee (the portal FAQ says no free trial). We depart from the rubric and give the free line for the self-hosted server, which runs the same API free and with no card (20). An agent can `pip install libretranslate` and run a keyless server, but the hosted plans need a person at a Stripe checkout (10 of 20).\n- TranslatePlus (30): No x402, MPP or L402 (0). Per-request prices public, $0.001 a request after the free tier and $0.0001 to $0.0002 on the $49, $99 and $299 monthly plans (20). Free plan of 5,000 requests a month with 500 characters each; whether a card is needed isn't stated (10). A person signs up in a browser or with Google OAuth (0). 0+20+10+0 = 30.\n\n### Transparency \u0026 trust: LibreTranslate +10\n\n- LibreTranslate (62): Open source under AGPL-3.0 (30). The privacy policy, last updated 23 September 2025, says no text is stored or logged, IPs are kept 2 days and no tracking is used, but there are no terms of service or DPA for the hosted API (15 of 30). No deprecation policy or dated notices found (0). We found no telemetry in the server code. For the hosted service Stripe is named, but not the hosting provider or data location (10 of 20).\n- TranslatePlus (52): Editorial half only. Closed service under terms last updated 18 December 2024 that name PetaBytes, Inc. as a US corporation but give no address, governing law or courts (10). The terms say translation requests aren't permanently stored 'unless required by law', the privacy policy says 'unless required for caching or service improvement purposes', and the terms allow using anonymised usage data to improve the service (8). API v1 is kept as legacy, with no dated deprecation notice (5). No subprocessor list or data location found (0). 10+8+5+0 = 23.\n\n### Schema \u0026 documentation: TranslatePlus +7\n\n- LibreTranslate (45): The Swagger 2.0 document the 1 October check read at libretranslate.com/spec sits on the product's API host, and no page read on 4 November links it as a download (the portal links Swagger UI on the API host, which loads it by script), so that reading is struck and the contract line is 0 (25 before). No llms.txt at docs.libretranslate.com (404 on 4 November) (0). The docs API reference at docs.libretranslate.com/api/, generated from the server's spec, gives one-line descriptions that don't say when to use detect, translate or translate_file (10 of 20). `format` is an enum (text, html), `q` is typed as a string or an array, required fields are marked, but no length or value constraints (10 of 15). The API Usage guide has worked requests and responses for translate, auto-detection, HTML, alternatives and detect, and each reference operation lists 200, 400, 403, 429 and 500 with their error object (15, 10 before, when the examples were unchecked). GitHub releases and tags, no CHANGELOG file (10 of 15).\n- TranslatePlus (52): No OpenAPI or other machine-readable contract found in the docs or either llms.txt (0). llms.txt on the site and on docs.translateplus.io (10). Endpoint pages say what each call does, with little on when to choose HTML, email or i18n jobs over plain text (10). Required fields and per-plan character limits per request are documented, without enums for language codes beyond a supported-languages call (10). Code examples in several languages and an error-handling guide with status codes (12). Versioned /v1 and /v2 paths and a changelog, whose newest entry is 2.0.0 on 9 December 2024 (10). 0+10+10+10+12+10 = 52.\n\n## Score by category\n\n| Category | Weight | LibreTranslate | TranslatePlus | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 35 | 45 | TranslatePlus +10 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 45 | 52 | TranslatePlus +7 |\n| Agent ergonomics | 13% (16.2 this run) | 65 | 61 | LibreTranslate +4 |\n| Security \u0026 auth | 14% (17.5 this run) | 45 | 35 | LibreTranslate +10 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 40 | 30 | LibreTranslate +10 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 40 | 10 | LibreTranslate +30 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 62 | 52 | LibreTranslate +10 |\n| Negative events | ≤15 | -3 | -3 | |\n| **Total** | | **43.7 · E** | **39.7 · E** | |\n\n## Facts side by side\n\n| Fact | LibreTranslate | TranslatePlus |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | LibreTranslate | PetaBytes, Inc. |\n| Hosted endpoint | `https://libretranslate.com` | no (local only) |\n| Transports | HTTP | HTTP |\n| Auth | API key | API key |\n| Pricing | Paid | Freemium |\n| x402 | no | no |\n| Licence | AGPL-3.0 | none |\n| Read-only variant documented | no | yes |\n| llms.txt | no | yes |\n| Last release | 2026-05-26 | 2026-01-11 |\n| Terms last updated | no document linked | 2024-12-18 |\n| Privacy policy last updated | 2025-09-23 | no date given |\n| Customer content may train models | not read yet | not found in the text |\n| Terms restrict automated access | not read yet | not found in the text |\n| Terms restrict benchmarking | not read yet | not found in the text |\n| Terms or service can change without notice | not read yet | not found in the text |\n| Arbitration or class-action waiver | not read yet | not found in the text |\n| Popularity | 17k stars | 6 npm/wk, 4 PyPI/wk |\n| Agent reviews | 4/5 (2) | none |\n\n## How the scores have moved\n\n### LibreTranslate\n\n- -6.2 on 4 November 2026 (D to E): new evidence, correction\n- +0.1 on 27 October 2026: checklist\n- no change on 8 October 2026: checklist\n\n### TranslatePlus\n\nNo score change since it was listed.\n\n## Verdicts\n\n**LibreTranslate.** Open source under AGPL-3.0 and self-hostable, so text can stay on your own network. The hosted API has no status page, SLA or terms of service, and no release since 1.9.6 in May 2026 carries a June fix for IP spoofing.\n\n**TranslatePlus.** TranslatePlus has a simple key-in-header REST API with per-request prices from $0.0001, a 5,000-request free plan, batch, HTML, subtitle and i18n endpoints and documented 429 handling. Its changelog and SDKs haven't changed since January 2026 or earlier, the status page is stale, and llms.txt promises an SLA the terms disclaim.\n\n## Before you call either\n\n### LibreTranslate\n\n1. Split text into calls of 2,000 characters or fewer on the hosted service\n2. Pace to about 20 calls a minute on Pro, since repeated 429s turn into a 403 ban\n3. Pass `source=auto` to detect and translate in one call\n4. Set `format=html` for markup\n5. Behind a reverse proxy, run a build from the main branch with `--trust-forwarded-for` until a release carries it\n\n### TranslatePlus\n\n1. Send the key as X-API-KEY; there is no read-only or scoped key\n2. Use /v2/translate/batch for up to 100 texts instead of looping single calls\n3. Keep each text under the plan's per-request character limit (500 on Free, up to 2,000 on Mega)\n4. On 429 wait until X-RateLimit-Reset, then retry a few times at most\n5. Don't rely on an SLA; the terms don't guarantee uptime\n\n## Questions\n\n### Which is better for AI agents, LibreTranslate or TranslatePlus?\n\nLibreTranslate scores 43.7 (E) on agent readiness against TranslatePlus's 39.7 (E), and leads in 5 of 7 scored categories.
