Every partner, system and message on one governed pipeline.
Bitween is the self-hosted integration platform for teams that can't afford to lose a message. Receive from APIs, brokers, databases and files; validate, map and deliver; and keep a searchable, replayable record of every exchange, inside your own infrastructure.

The platform
One pipeline for every way data enters and leaves your business.
Point-to-point scripts hide failures until a customer finds them. Bitween replaces them with one consistent pipeline that validates, transforms, delivers, retries and records, whatever the protocol.
Product tour
Built for the people who keep integrations running.
Operators, integration developers and support teams share one browser-based workspace, with permissions that show each person exactly what they need.
Dashboard
Know what needs attention before anyone asks.
- Failures still to act on
- Retry chains that keep failing
- Unhealthy and busiest subscriptions

How it works
Follow one message through Bitween.
Every exchange, whether it comes from a partner API call, a queue or a scheduled pull, runs through the same stages and leaves the same evidence behind.
Step 1 · Arrive
Many ways in, one pipeline.
A partner calls an API gateway, a message lands on a bus gateway, or a scheduled job pulls from S3, SFTP, a mailbox or a database. Every entry point leads into the same pipeline.

Visual mapping
JSON in, XML out. No document ever sent with gaps.
Build rules from real samples: paths, fixed values, partner and global values, transforms, lookups and list filters. Every rule is attempted, and if one fails the exchange fails with the reason.
- Decimal-exact numbers: 100 × 1.16 is exactly 116
- Ambiguous dates refused, never guessed
- XML namespaces, attributes and repeated elements
- Server-side preview through the pipeline’s own code

Reliability
Retry what's safe. Block what isn't. Alert once.
Retry policies decide per failure: transient network errors wait and try again within a budget, validation errors never repeat, and when a shared budget runs out one alert reaches the right team.

Solutions
Proven integration patterns for your industry.
The same pipeline, applied to the flows each industry depends on, described in terms of what Bitween does today.
Deployment & trust
Your infrastructure. Your compliance scope.
Bitween runs where your data already lives. No vendor cloud in the path, no per-message metering, and nothing to phone home to.
Scale out with replicas
Add replicas behind a load balancer and tune prefetch per work group.
Choose your stack
PostgreSQL, SQL Server or MySQL; S3, Azure Blob or Oracle Cloud storage.
Enterprise sign-in
Microsoft Entra ID sign-in and Azure managed identity for databases.
Bitween AI is coming, with the guardrails integration already has.
AI that drafts, explains and acts should be permissioned, previewed and audited like everything else in your integration layer. That's what we're building.
AI-assisted mapping
Draft mapping rules from a source and target sample, then review them in the live preview.
Failure explanations
Plain-language summaries of why a retry chain keeps failing, and what to change.
MCP server for agents
Let AI agents work with Bitween through tools that respect roles and land in the audit trail.

FAQ
Questions architects ask us.
Can't find your answer? The documentation is written straight from the source code, or ask an architect directly.
Is Bitween really free?
Yes. Bitween is open source under the MIT License, with every feature, unlimited integrations, partners and users. Simplify9 offers optional support packages and integration services for teams that want expert help.
Where does my data live?
In your infrastructure. Bitween runs as a container in your cloud account or data centre, stores configuration, exchanges and the audit trail in your database, and writes payloads to your object storage. No Simplify9-operated service sits in the data path.
What do I need to run it?
A container runtime or Kubernetes, a PostgreSQL, SQL Server or MySQL 8 database, RabbitMQ, and S3-compatible, Azure Blob or Oracle Cloud object storage. A Helm chart and a Docker image are provided.
Can we build our own connectors?
Yes. A custom adapter is a small program that implements a simple contract for receiving, validating, mapping or delivering. Bitween runs it out of process, either per call or as a long-lived resident process that keeps connections open.
What happens when a partner endpoint is down?
The exchange fails with its reason and your retry policy decides: which errors are retried, how long to wait, how many attempts per message and how many in total. When a shared budget is spent, retries stop and one alert is sent. Every attempt is kept in a retry chain you can follow and retry by hand.
Does Bitween handle EDI or HL7?
Bitween maps JSON and XML natively, in either direction, including XML namespaces. Flat and delimited formats such as X12, EDIFACT or HL7 v2 are handled by a custom adapter that translates them before or after mapping.
How does Bitween compare with MuleSoft or Boomi?
Those are broad, cloud-first platforms with large connector catalogues and matching price tags. Bitween is focused on reliable message exchange with partners, brokers, databases and files, runs entirely in your environment, and costs nothing to license. Our comparison page walks through the differences.
When is Bitween AI available?
Bitween AI is in development. We share progress with early-access teams first. Tell us about your use case and we will keep you in the loop.
