## Which one, for what

### Localazy (C)

Good for: App and game teams that keep source strings in a TMS and want agents to push keys, pull translations or run AI translation with a glossary.

Ahead on:
- Reliability, 68 against 45
- Payments & pricing, 35 against 30
- Maintenance & community, 75 against 10
- Transparency & trust, 57 against 52

Also in its favour:
- Free to start without a card
- No incidents deducted, where TranslatePlus loses 3 points for them

Watch for: No OpenAPI spec, and llms.txt only lists top-level pages

### TranslatePlus (E)

Good for: Low-cost per-request translation of short strings, HTML, emails, subtitles and i18n files for small projects.

Watch for: llms.txt claims a 99.9% uptime SLA and SOC 2 Type II, while the terms disclaim any uptime guarantee and no audit is named


## Why the edge

### Maintenance & community: Localazy +65

- Localazy (75): @localazy/api-client 2.3.2 on 26 October 2026 (30). Releases 2.3.0 (12 August), 2.3.1 (29 September) and 2.3.2 (26 October) in the last 90 days (20). Support by email, blog release updates, and public GitHub repositories, but we didn't read issue reply times (7). The TypeScript client and the CLI (2.0.12 on 31 July 2026) are current (13). The client repository shows coverage badges; we didn't confirm CI runs (5). 30+20+7+13+5 = 75.
- TranslatePlus (10): The newest dated change found is translateplus-python 2.0.7 and translateplus-js 2.0.1 on 11 January 2026, about ten months before this check, and the API changelog stops at 9 December 2024 (0). No release or dated change in the last 90 days (0). Support by email and a support portal; the status page hasn't updated since January (3). SDKs exist for four languages but haven't changed since January (5). Weekly downloads of 4 (PyPI) and 6 (npm) (2). 0+0+3+5+2 = 10.

### Reliability: Localazy +23

- Localazy (68): Hosted lines, for the REST API at api.localazy.com. Better Stack status page with Web, API, Public API, Payments and Connect API components and 30, 60 and 90-day uptime (20). The incidents page reports none for September, October or November 2026, but the Public API shows 99.805% uptime in one 30-day bucket, roughly an hour and a half of downtime with no incident posted, so the line is held below clean (25). Limits per plan of 100 requests a minute and 10 a second, plus daily import and fetch caps per project (15). No 429 or retry guidance found in the API docs (0). No SLA found on the pricing page or in the terms (0). The core API is GA; the AI Translation endpoint is marked beta (8). 20+25+15+0+0+8 = 68.
- 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). The rate-limits guide gives 100,000 requests a minute and 100,000,000 an hour per key, while llms.txt gives 50 requests a second on the Free plan, so limits are published but inconsistent (10). 429 returns a JSON detail message, responses carry X-RateLimit-Limit, -Remaining and -Reset, and the guide shows waiting for the reset with capped retries (15). No SLA. The terms say TranslatePlus strives for 99.9% uptime 'but do not guarantee uninterrupted service' (0). API v2 is the current, non-beta version (10). 5+5+10+15+0+10 = 45.

### Payments & pricing: Localazy +5

- Localazy (35): No x402, MPP or L402 (0). Plan prices are public ($34, $78 and $175 a month billed annually) and credits are $1 each, with Localazy AI at about $0.005 a word on average, so partial per-unit credit (15). A free plan for small projects and a 14-day Business trial with no credit card (20). A person signs up in a browser and mints tokens in the developer settings (0). 0+15+20+0 = 35.
- 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.

### Transparency & trust: Localazy +5

- Localazy (57): Editorial half only. Closed service under terms that name Localazy s.r.o. of Brno and Czech law; the CLI is BSD-3-Clause and the API client MIT (15). The privacy policy keeps data while the service is used and 24 months after, and includes a DPA, but says nothing on whether content sent to Localazy AI is used for training (15). No deprecation policy or dated notices found (0). The DPA links a list of suppliers and subprocessors on an external knowledge base we didn't read (10). 15+15+0+10 = 40.
- 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.

## Verdicts

**Localazy.** Localazy is a localisation platform whose REST API, CLI and AI Translation endpoint use project-scoped bearer tokens, with published limits, a free plan and a no-card trial. There's no OpenAPI spec, no 429 guidance, no security.txt or disclosure policy, and project tokens carry full read and write access.

**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.

## Before you call either

### Localazy

1. Ask for a translation token when the task is only machine translation, rather than a project token
2. Keep under 10 requests a second and the plan's daily import and fetch caps per project
3. Use the Localazy CDN, not the API, to fetch translations in a live app
4. Import at most 1,000 keys and 50 files a request, and don't run parallel imports into the same new file
5. Check the account's credit balance before bulk AI translation, since each word uses credits

### TranslatePlus

1. Send the key as X-API-KEY; there is no read-only or scoped key
2. Use /v2/translate/batch for up to 100 texts instead of looping single calls
3. Keep each text under the plan's per-request character limit (500 on Free, up to 2,000 on Mega)
4. On 429 wait until X-RateLimit-Reset, then retry a few times at most
5. Don't rely on an SLA; the terms don't guarantee uptime
