01
Operator-owned.
Evidence, credentials, memory, and customer relationships live with the operator — not the vendor, not the model provider, not whatever harness was special last quarter.
Agentic substratefor unusually autonomoussoftware businesses.
Operator-owned. Vendor-neutral. Built to compound.
Most companies still keep a human in every loop. Bitter is the substrate underneath the ones that don't — owned evidence, scoped credentials, durable memory, machine-operable surfaces, and the portfolio of market surfaces an agent-run business needs to compound.
Preview build. Starts local, inside your repo.
Owned evidence.
Scoped credentials.
Durable memory.
Cleverness erodes. Substrate compounds.
Compute keeps getting cheaper. General methods keep getting more capable. Clever code, clever prompts, clever harnesses get absorbed every release. What stays is the substrate underneath: evidence, credentials, memory, surfaces, and the market surfaces a business compounds on. Bitter is the operator's side of that substrate.
the substrate
Models commoditize. Harnesses get absorbed. The substrate is the asset — owned by the operator, shaped for autonomous work, and built to compound across every wave of cheaper, stronger compute.
02
Machine-operable.
Surfaces shaped for autonomous work: scoped credential grants, deploy lanes, durable run history, browser checks, and configs agents can act on without bespoke orchestration.
03
Built to compound.
Every run leaves the ground better than it found it. Receipts feed the next loop. Owned domains, brand memory, and search presence keep accumulating value as software formation gets cheaper.
Bitter Factory
The hosted half of the substrate.
One sign-in gives the local CLI hosted runners, durable evidence, scoped credentials, backups, deploy lanes, credits, email, and a web dashboard. The substrate, kept on the operator's side.
install
High agency without high ceremony.
Bitter starts local. Credentials stay scoped. Evidence stays owned. The substrate stays yours.
Works with BitterPass, BitterLog, BitterGrid, and GoltMund.
Preview build. Requires Bun.
Use the frontier. Keep your ground.
