OpenParser
Best alternatives to OpenParser in 2026
Extracting usable text and structure out of a scanned PDF or an image of a document is a problem nearly every data pipeline hits eventually, and most solutions to it are proprietary APIs with per-page pricing. OpenParser takes the alternative route: an open-source, self-controllable document parser you can run as part of your own stack rather than sending documents to a third party. OpenParser is Apache-2.0 licensed and parses PDFs and images using OCR (PaddleOCR-VL-1.6) alongside layout and structured-data extraction, exposed through TypeScript and Python SDKs plus a CLI built for terminal and CI/CD use. It handles runtime validation and schema generation, converts provider responses through adapters, and includes synchronous parsing operations behind a web-based authentication system. The project is genuinely early — around 5 commits at the time of research — and is distributed as several packages (@openparser/sdk, openparser-sdk, @openparser/cli, @openparser/schema, @openparser/adapters), built using the Bun package manager.

#1
- ✓ Déploie sans transfert de données dans le compte AWS du client
- ✓ 250+ vérifications automatisées en continu
#2
One of the most widely used API gateways — the layer that sits in front of a company's APIs to route, secure, rate-limit and monitor traffic — now expanding into managing AI model traffic and token costs the same way.
konghq.com
- ✓ Free, battle-tested open-source Gateway tier
- ✓ Now covers AI/LLM traffic with token optimization and semantic caching
#3
Gives platform teams a self-service portal where developers can spin up infrastructure themselves through simple forms, instead of filing a ticket and waiting on the ops team.
cycloid.io
- ✓ Ready-to-use self-service portal, no need to build on Backstage yourself
- ✓ GitOps-first with Infrastructure-as-Code baked in
#4
A centralized hub where a company's engineering team can catalog every API they run, publish interactive documentation for each one, and control who inside or outside the company gets access.
api-portal.io
- ✓ Supports OpenAPI, Swagger, AsyncAPI, GraphQL and RAML in one catalog
- ✓ Interactive try-it-out documentation in the browser
#5
An open-source 'engineering memory' tool that pulls together GitHub, CI logs, Kubernetes, and Sentry into one place, so a team investigating an incident isn't stuck re-piecing together the same story from five different dashboards every time.
github.com
- ✓ Open-source (Apache-2.0), self-hostable and auditable
- ✓ Lightweight Rust CLI, one-command install
#6
A free, open-source Python testing tool that snapshot-tests AI agents — recording every LLM and tool call so you can catch when a prompt tweak or model swap silently breaks your agent's behavior.
github.com
- ✓ Free and open-source (MIT)
- ✓ Three-tier regression detection (structural/argument/semantic)
#7
A cloud hosting platform where your app runs in its own tiny virtual computer that can be instantly copied — so testing a risky change or spinning up a preview for a teammate takes seconds, not a whole new deployment.
kedge.dev
- ✓ Fork instantané d'une VM en cours d'exécution
- ✓ Base SQLite globale incluse
#8
Open-source tooling for creating fully isolated virtual Kubernetes clusters inside a single real cluster — each tenant gets what feels like their own Kubernetes, without the cost and overhead of actually running separate clusters.
vcluster.com
- ✓ Free and open-source core product
- ✓ Free tier covers meaningful usage (64 CPUs/32 GPUs)
#9
An AI agent named Aiden that handles the parts of the DevOps job that usually eat up an SRE's night — incident response, generating infrastructure-as-code, observability, and CI/CD tuning — across multi-cloud setups.
stackgen.com
- ✓ Single AI agent (Aiden) covers incident response, IaC, observability, and CI/CD
- ✓ Aimed at reducing SRE toil across the whole DevOps lifecycle
#10
A cloud management tool that watches how your applications actually behave and adjusts resources — scaling, costs, availability — on its own using reinforcement learning, instead of an engineer setting static rules that go stale.
sedai.io
- ✓ Reinforcement learning adapts continuously vs. static scaling rules
- ✓ Covers AWS, Azure, and Google Cloud in one platform
#11
A FinOps tool that automatically buys and manages the cloud discount commitments (Reserved Instances, Savings Plans) that most teams either skip entirely or manage badly by hand, and breaks down cloud spend hour by hour instead of one confusing monthly bi
nops.io
- ✓ Automates Reserved Instance / Savings Plan / CUD management continuously
- ✓ Hour-by-hour cost allocation instead of one monthly lump sum
#12
An open-source toolkit that lets a platform team build a self-service capability once — say, "spin up a database" — and hand it out to developers, automation scripts, and now AI agents through a consistent API, CLI, or portal.
kratix.io
- ✓ Free, open-source (Apache 2.0) core — no cost to start
- ✓ MCP support lets AI agents request infrastructure like human developers do
