Which one, for what

Lingvanex Translation API F

Good for Bulk translation of non-sensitive text where price per character matters most, or buyers who want an on-premise server later.

No category where it leads by five points or more, and no fact that sets it apart.

Watch for

Product pages disagree on bulk and on-premise prices

Lokalise BB

Good for Agents that manage localisation work, such as adding keys, uploading and exporting string files, keeping a glossary and starting AI or machine translation tasks for a team that already uses Lokalise.

Verdicts

Lingvanex Translation API

$5 per million characters list price. Product pages disagree on bulk and on-premise prices.

Lokalise

The REST API has public OpenAPI files, Markdown docs, published rate limits, read-only tokens, scoped OAuth and an audit log endpoint. Access needs a paid plan after a 14-day trial, a person signs up in a browser, and the Master Service Agreement forbids benchmarking. No idempotency keys or deprecation policy were found in the reviewed documentation.

Before you call either

Lingvanex Translation API

  1. Call the https:// server, not the http:// one the spec also lists
  2. Send platform as api on every call, since the spec marks it required
  3. Use locale codes such as en_GB and de_DE, not two-letter codes
  4. Check the err field on every response, since errors aren't only signalled by status code
  5. Send an array in data to translate several strings in one call

Lokalise

  1. Send the token in the X-Api-Token header to https://api.lokalise.com/api2. OAuth access tokens go in Authorization: Bearer and expire after about 60 minutes.
  2. Stay under 6 requests a second per token and 10 concurrent requests per project. On 429, back off exponentially and read X-RateLimit-Reset.
  3. Use a read-only token for reads. A read/write token can call PUT /projects/{project_id}/empty, which deletes every key and translation.
  4. Use pagination=cursor on /keys and /translations, with limit at most 500 on keys, and follow X-Pagination-Next-Cursor.
  5. Projects above 10,000 key-language pairs need /files/async-download. Poll /processes/{process_id} for the bundle URL, and do the same after /files/upload.
