Building an Enterprise Agent Platform Without Buying Everything
Lists of must-have agent repositories circulate faster than anyone can check them. They mix frameworks, SDKs, workflow tools, memory systems and coding agents as if they were interchangeable, and they rarely say what any of them leaves undone. This four-part series follows Sneeuberg Insurance, a fictional South African short-term insurer, as its platform team builds a dated matrix of twenty real repositories across five capability families. It then separates orchestration from the tool protocol, defines framework, SDK, workflow tool and agent platform by the responsibility each one takes, and records the current status of five named frameworks. The series closes by choosing the smallest stack that meets an agent's autonomy tier, and by naming who patches, supports and eventually retires every component, including the free ones. Research claims were checked on 7 November 2026.

- Part 1Twenty agent repositories, five capability familiesLists of must-have agent repositories mix frameworks, SDKs, workflow tools, memory systems and coding agents as if they were interchangeable. Part 1 of Building an Enterprise Agent Platform Without Buying Everything sorts twenty real repositories into five capability families, records what each one owns and does not own, and dates every entry.12 min read
- Part 2LangGraph and MCP solve different problemsArchitecture reviews keep asking whether a team should use LangGraph or MCP, as if the two were alternatives. Part 2 of Building an Enterprise Agent Platform Without Buying Everything separates orchestration from the tool protocol, follows one insurance claim through both, and shows the controls that neither of them supplies.9 min read
- Part 3Framework, SDK, workflow tool or agent platform?Agent products describe themselves with overlapping words, so teams compare an SDK with a hosted platform and wonder why the comparison feels wrong. Part 3 of Building an Enterprise Agent Platform Without Buying Everything defines four categories by responsibility, records the status of five named frameworks as checked on 7 November 2026, and gives scenario-based guidance instead of a ranking.10 min read
- Part 4Choose the smallest agent stack that can survive productionThe cheapest agent platform is the one with the fewest components that still meets its autonomy tier, and open-source components still need an owner who patches, supports and eventually retires them. Part 4 of Building an Enterprise Agent Platform Without Buying Everything sets minimum stacks by autonomy tier, sorts each component into build, buy, reuse or avoid, and plans the exit before the entry.9 min read
Working through any of this in your own organisation?
These articles come out of delivery work rather than theory. If the problems in this series look familiar, a short scoping conversation is usually the quickest way to work out what is worth doing first.
