TurboOCR
Self-hosted GPU document parser: PP-OCRv6 on TensorRT, up to 559 img/s on one RTX 5090.
TurboOCR is the fastest self-hosted OCR server we have seen benchmarked, hitting up to 559 img/s on receipts and ~520 img/s on forms on a single RTX 5090, with full structured parsing (layout + tables + formulas) at ~20 pages/s against roughly 1 page/s for VLM parsers like PaddleOCR-VL on the vendor's OmniDocBench subset. If you already own an NVIDIA GPU and need low-latency extraction for receipts, invoices, forms or PDFs, the C++/TensorRT pipeline is hard to beat on throughput, and MIT licensing plus a one-line Docker deploy keeps the lock-in low. Compare it against a Python PaddleOCR stack (same PP-OCRv6 weights, far slower runtime) and against managed APIs such as Google Document AI or

Skip TurboOCR if your bottleneck is extraction quality on genuinely messy documents rather than speed or data locality — its own docs put it at 0.90 Overall on a 125-doc OmniDocBench subset against 0.95 for PaddleOCR-VL, and you would be trading accuracy for throughput you may not need.
Running the documented ~20 pages/s of full structured parsing means the layout, table and formula stages all execute, so a small GPU that flies on text-only OCR can become the bottleneck once you enable ?tables=1 and
TurboOCR ships under an MIT licence as source plus a Docker image, so the software cost comparison is against other free, self-hosted OCR runtimes (a Python PaddleOCR stack uses the same PP-OCRv6 weights) rather than against per-page managed APIs like Google Document AI or AWS Textract. Your real budget line is the GPU: one RTX 5090 class card carries the published 559 img/s figure, and smaller or older Turing cards will land well below it.
In short
TurboOCR — Self-hosted GPU document parser: PP-OCRv6 on TensorRT, up to 559 img/s on one RTX 5090. Best for High-volume pipelines processing millions of pages, DevOps teams needing self-hosted, low-latency extraction, Organizations with data-residency requirements. Free to use.
What is TurboOCR?
TurboOCR — Self-hosted GPU document parser: PP-OCRv6 on TensorRT, up to 559 img/s on one RTX 5090. Best for High-volume pipelines processing millions of pages, DevOps teams needing self-hosted, low-latency extraction, Organizations with data-residency requirements. Free to use.
TurboOCR is a self-hosted GPU document parser rather than a plain OCR endpoint. It runs PP-OCRv6 text detection and recognition together with layout, table, formula and reading-order stages in one native C++/CUDA/TensorRT pipeline, and it exposes both HTTP and gRPC from a single binary. You POST an image or PDF and get structured JSON back with line text, confidence scores, four-point bounding polygons, and optional layout regions, tables and formulas. Version 3.2 added layout-aware OCR, native PDF support and TensorRT acceleration; the PDF path renders pages through a PDFium worker pool into the same GPU pipeline, with optional page-image export and auto-rotation. Throughput is documented at up to 559 images/sec on receipts and roughly 520 img/s on forms on a single RTX 5090, with full structured parsing (layout + tables + formulas) at about 20 pages/sec — the docs contrast that with VLM document parsers such as PaddleOCR-VL at roughly 1 page/sec. Accuracy is quoted as 92% word-F1 on FUNSD and 93% on CORD on the medium PP-OCRv6 tier, which is English/Latin-script; the default tier is tiny for maximum speed and you switch with OCR_MODEL. Layout detection uses PP-DocLayoutV3 (RT-DETR-L, 25 region classes) on by default via ?layout=1; tables convert to HTML with SLANet-Plus (TABLE_BACKEND=slanext + ?tables=1); formulas render to LaTeX with in-process PP-FormulaNet-S (FORMULA_BACKEND=ppformulanet_s + ?formulas=1). POST /ocr/markdown returns faithful Markdown with tables and formulas inline. Deployment is a one-line Docker run from ghcr.io/aiptimizer/turboocr; TensorRT engines build on first start and cache to a named volume. GET /capabilities reports which stages are loaded and /metrics exposes Prometheus request counters, latency histograms and VRAM usage. It is MIT licensed and open source. It fits developers and teams running high-throughput, latency-sensitive document pipelines where no data may leave the network — you need Linux, an NVIDIA Turing-or-newer GPU and some Docker comfort.

Models under the hood
as of 2026-10-22
Limitations
- TurboOCR is self-hosted and GPU-bound: you need Linux plus an NVIDIA Turing-or-newer GPU, and deployment assumes some Docker comfort.
- Throughput is hardware-specific — up to 559 img/s on receipts and ~520 img/s on forms on one RTX 5090, with full structured parsing (layout + tables + formulas) at ~20 pages/s.
- The default PP-OCRv6 tier is tiny and chosen for maximum throughput; the 92% FUNSD / 93% CORD word-F1 figures apply to the medium tier and to English/Latin-script documents.
- On the vendor's own 125-document OmniDocBench subset TurboOCR scores 0.90 Overall versus 0.95 for PaddleOCR-VL at ~1 page/s, so on hard pages a VLM parser may extract more than the speed advantage is worth.
- PP-OCRv6 covers Latin plus Chinese and Japanese; Arabic, Cyrillic, Korean, Thai and Greek rely on retained PP-OCRv5 recognizers.
- There is no handwriting recognition.

Where the pricing makes sense
The company stage and team size where TurboOCR's pricing actually pencils out — and where peers do it cheaper.
TurboOCR ships under an MIT licence as source plus a Docker image, so the software cost comparison is against other free, self-hosted OCR runtimes (a Python PaddleOCR stack uses the same PP-OCRv6 weights) rather than against per-page managed APIs like Google Document AI or AWS Textract. Your real budget line is the GPU: one RTX 5090 class card carries the published 559 img/s figure, and smaller or older Turing cards will land well below it.
Has TurboOCR's pricing changed?
No plan price for TurboOCR has moved since we began logging in Aug 2026; the pricing page is re-read on every verification pass.
Who should pick TurboOCR?
Pick TurboOCR if you are High-volume pipelines processing millions of pages, DevOps teams needing self-hosted, low-latency extraction, Organizations with data-residency requirements, Developers integrating OCR via HTTP/gRPC.
Look elsewhere if you are Non-technical users wanting a no-code web UI, Teams without an NVIDIA Turing-or-newer GPU, Projects requiring handwriting recognition, Teams wanting a fully managed service with zero infrastructure.
Skip it if Skip TurboOCR if your bottleneck is extraction quality on genuinely messy documents rather than speed or data locality — its own docs put it at 0.90 Overall on a 125-doc OmniDocBench subset against 0.95 for PaddleOCR-VL, and you would be trading accuracy for throughput you may not need.
GeneratedReal-world workflow fit
Concrete scenarios for the personas TurboOCR actually fits — and what changes day-one when you adopt it.
You pull ghcr.io/aiptimizer/turboocr, run it with Docker on a Linux box with an RTX 5090, wait for the TensorRT engines to build on first start, then POST receipt images to /ocr/raw and read back line text, confidence and four-point bounding polygons over HTTP.
Outcome: Your backlog that took roughly a page per second on a VLM parser now runs at up to 559 img/s, and the same service answers gRPC calls from your existing pipeline without a second deployment.
You POST PDFs into the same endpoint, letting the PDFium worker pool render pages into the GPU pipeline with auto-rotation, and enable ?layout=1, TABLE_BACKEND=slanext with ?tables=1, and FORMULA_BACKEND=ppformulanet_s with ?formulas=1 for the pages that need it.
Outcome: Each request returns layout regions, tables as HTML and formulas as LaTeX alongside the text, and POST /ocr/markdown gives you faithful Markdown with the tables and formulas inline for downstream ingestion.
You check GET /capabilities on boot to confirm which stages loaded, wire /metrics into Prometheus for request counters, latency histograms and VRAM usage, and keep the container inside the private network with no outbound calls.
Outcome: You can prove no document leaves the network, alert on VRAM headroom before throughput degrades, and size additional replicas against measured latency rather than guesswork.
Use cases
- OCR high volumes of scanned receipts and forms in real time
- Extract text, layout regions, tables and formulas from a single request
- Build a custom document processing API over HTTP or gRPC
- Run on-premises document parsing so no data leaves your network
- Replace a Python-based PaddleOCR pipeline with a faster C++/TensorRT runtime
- Monitor OCR throughput, latency and VRAM in production with Prometheus
- Convert PDF pages into structured JSON or Markdown with tables inline
- Process mixed Latin, Chinese and Japanese documents with one model
Setup time & first value
How long it actually takes to get something useful out of TurboOCR — broken out by persona, not the marketing-page minute.
For a developer who already runs Docker on a Linux host with an NVIDIA Turing-or-newer GPU: minutes to the first successful POST, plus the TensorRT engine build on first container start, which then caches to a named volume. Budget longer — realistically an afternoon — if you are still installing CUDA drivers or deciding between the tiny, small and medium OCR_MODEL tiers for your accuracy target.
Switching to or from TurboOCR
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a Python PaddleOCR pipeline: the docs position TurboOCR as the same PP-OCRv6 weights in a C++/TensorRT runtime, so you keep your model expectations and swap the serving path.
- →From a managed OCR API: route POSTs to your own TurboOCR container instead, and accept that you now own the GPU host, driver upgrades and capacity planning.
- →From a VLM document parser such as PaddleOCR-VL: move only the high-volume, latency-sensitive document types across first, since the vendor's own OmniDocBench comparison still favours the VLM on overall extraction
- →From another self-hosted OCR server: reuse your existing HTTP client and point it at TurboOCR if gRPC is not already in your stack.
- ↗To a managed API such as Google Document AI or AWS Textract: swap the HTTP endpoint, and accept the per-request fee, data egress and network dependency you were avoiding.
- ↗To PaddleOCR in Python: run the same PP-OCRv6 weights without the TensorRT serving layer, trading throughput for a simpler, GPU-optional deployment.
- ↗To a VLM document parser like PaddleOCR-VL: keep TurboOCR alongside it and route the documents where quality matters more than pages per second.
- ↗To a commercial IDP platform: replace the HTTP/gRPC calls with the vendor's SDK and let them own the document schema end to end.
